                        Overview

   Computer Aided Flight Planning (CAFP) is a program designed to assist the
pilot of single engine and light twin engine airplanes in many of the routine
but time-consuming tasks of flight planning.  It is not intended to replace
the  decision making role of the pilot in command but rather to  provide
assistance, much as a co-pilot might.  Specifically, the  program  provides
selection of routes; creation, storage, and retrieval of flight plans; weight
and balance computations; creation of flight logs; and communication with
weather services such as DUAT.  These items can be printed and taken
along in flight.   

     Users of CAFP are cautioned to regard the system displays and reports
as advisory and/or approximate, not as fact on which to rely.  As in all good
flight planning, the pilot should verify CAFP information by cross reference
to independent sources.  These sources include, but are not limited to, 
pre-flight  weather briefings, the Airman's Information Manual,  NOTAMS,
airport directories, and current charts and maps.  Additionally, users must
be aware of the specific requirements  and capabilities of their airplane
before utilizing any information provided by CAFP.


Quick Start

   The following information is for individuals who are familiar with
computer hardware and operating systems.  It is an abbreviated set of
instructions for quickly installing CAFP and initiating its execution.  If you
need more detailed guidance, please proceed to the next section.

    If your computer has a hard disk, then create a sub-directory named
\CAFP and copy all the files from the floppy disk to the sub-directory,
otherwise you may execute directly from a floppy.  Next, log to the sub-
directory or floppy and start the program with the command CAFP.  The
command line may optionally have three parameters;  LPT2 will cause
printed output to go to the second parallel port, BW will force the display
to monochrome, and L will cause printed versions of the flight log to include
latitude and longitude of all waypoints.

                     Preliminaries

       Making a working disk
     The  disk you have received is called the distribution disk.  You should
make a copy of this disk and work with the copy  (We'll call the  copy  the
working disk).  Then, if something should go wrong with the working disk, 
you can make another copy from the distribution disk.  So, let's begin by
making a working disk.  Start by  booting your computer.  The next steps
to use depend on the number and type of disk drives you have.  Select yours
from one of  the following three alternatives:

              I  Two floppy disk drives:
                 o  Put your DOS system disk in drive a:
                 o  Put a blank disk in drive b:
                 o  At the system prompt ( A:> ) enter
                    the following command:   format b:
                 o  Remove the DOS system disk from drive a:
                 o  Put the distribution disk in drive a:
                 o  Enter the following command:
                             copy a:*.*  b:
                 
              II One floppy disk drive:
                 o  Put your DOS system disk in drive a:
                 o  At the system prompt ( A:> ) enter the
                    following command:   format b:
                    (Follow the directions.  The disk for drive a: is the
                     DOS disk.  The disk for drive b: is a blank disk.)
                 o  Remove the DOS system disk from drive a:
                 o  Put the distribution disk in drive a:
                 o  Enter the following command:   copy a:*.*  b:
                    (Again follow the on-screen directions.  The
                     disk for drive a: is the distribution disk.
                     The disk for drive b: is the blank disk.
                     You will exchange disks several times.)
                 
              III One or more floppy disk drives and a hard disk (drive c:):
                 o  Put the distribution disk in drive a: (or b:)
                 o  Create a subdirectory on drive c: (or other drive
                    designation) with the following command:  md c:\cafp
                 o  Change to the new subdirectory:   c:\cafp
                 o  Copy all files from the distribution disk
                     to the subdirectory:    copy a:*.*  c:\cafp
                 

The files on your disk

    CAFP.EXE & CAFP.OVR - The main program files.

    CAFPCOMM.EXE - The communication program file.

    DATAFILE - This file contains data about VOR stations.  You may            
    alter the contents of this file by adding data on any additional facilities 
    (for example, airports).  You can also delete data from this file.         
    Procedures for altering the data are described in the section
    DATA MAINTENANCE.

    CONFIG.DAT - This file holds data about your airplane.  One of the
    first things you should do with CAFP (described in the next section)
    is to configure the system to your airplane(s).  As you supply data
    about your airplane the data is automatically added to this file.

    WEATHER.DAT - This file stores the winds aloft data.  In order to
    compute estimates for the time enroute and ground speed,  winds aloft
    data are needed.  CAFP has a simple procedure for entering the
    winds aloft data into this file.

    WTBAL.DAT - Similar to the CONFIG.DAT file.  The data on this
    file contains weight and balance data for your airplane.

    WX.DAT  - If you use the communication feature to capture weather
    data, the data is stored in this file.

    COMM.DAT - This file contains data used to establish
    communications with DUAT.

    *.BGI - Files ending in BGI are used for graphics displays.
    CGA.BGI for CGA graphics adapters;  EGAVGA.BGI for EGA and VGA
    adapters; HERC.BGI for Hercules adapters; ATT.BGI for AT&T
    systems; and PC3270 for IBM PC 3270 systems.  You may delete any
    unneeded BGI files, but no harm results from keeping them.
     As you use CAFP, the computer will create additional files.  The names
of these files will end with the letters RTE or PLN.  Any file whose name
ends in RTE is a route file.  Route files contain data about a sequence of 
VOR stations or other facilities that define a route from the origin to the
destination. The first eight letters of a route file name consists of the origin
identifier and the destination identifier.  For example, the route file name
for a route from the Memphis airport to the New Orleans Airport is:
                   MEMAMSYA.RTE
                     MEMA = Memphis airport
                     MSYA = New Orleans airport
                     RTE  = Route file

As you may have guessed from the above example, CAFP uses the three 
letter code for facility identification plus one additional letter chosen from 
the following:
                   A = Airport
                   V = VOR (low altitude and high altitude)
                   T = Terminal VOR

     The other file type mentioned above is PLN.  Any file whose name 
ends with PLN is a flight plan file.  Flight plan files contain the same
information you normally specify in creating a regular flight plan.  They  use
the same convention for the first eight letters that the RTE files use.


The keyboard

     In order to use CAFP there are several keys you should be familiar 
with. Locate on your keyboard a large key labeled with an arrow with an 
upward turning tail. It might be labeled with the word Enter or Return.  
This key (we'll call it the entry key) must be pressed after each entry  you 
make. Also, find the four keys located near each other with an arrow 
pointing  up, down, left and right.  These keys are the cursor movement keys
and are used to move around the various screens which will appear as you
use CAFP.  By the way, don't worry about typing errors.  You can't do any
damage by typing the wrong thing.  If you do make a mistake, just press the
entry key and type it again.  You can use the Del key to delete items and
the Backspace key to backup and re-enter items.


Starting CAFP

        If you are using a computer with no hard disk drive;
                Put the working disk in drive a: or b:
                Log to the drive containing the working disk
                 by entering a: or b:  
                Next enter the command:
                             cafp

        If you are using a hard disk;
                Enter the command:
                             cd \cafp
                Next enter the command:
                             cafp

     You will now see the opening screen.  Now press any key and this 
screen will disappear and the Main Menu should appear.

     If  these  screens look fuzzy or difficult to read then you  should  exit
from CAFP by pressing the Esc key. Now re-start CAFP by entering the
command:
                             cafp bw
The  letters bw force the display into black and white (monochrome mode). 
If you  have  a monochrome monitor and a graphics video controller you 
will use this bw form of the command to start CAFP.  If you want to force 
your video controller into color/graphics mode, then start with the
command:
                             cafp co

     If you have a printer attached, there is an optional parameter available
which will affect how your printer is used.  If you select any of the CAFP
options that cause printing to occur and you get no print-out, it may be
because your printer is connected to the second printer port.  In that  case
you should start CAFP with the command: cafp lpt2  You can combine both
features in one command as in: cafp bw lpt2

     The second screen is called the main menu.  From the main menu you 
may select any of the options by typing the number of your choice and
pressing the entry key, or by moving the highlight bar with the cursor
movement keys and pressing the entry key.  Here's a brief description of
each option.  Details will follow in the next sections.

Route
       This option is used to create a route.  A route is a sequence of VOR
stations (and other facilities) which define how you intend to fly from the
origin to the destination.  You can enter the sequence of facilities  yourself
or you can let CAFP suggest a sequence or you can use a combination of
computer suggestions and your own requirements.  This option is also used
to display maps of your route and weather radar data.

Weather
       The weather option is used to enter the winds aloft and connect to
DUAT.  After you have obtained winds aloft data it is important to enter
them with this option.  The computer will automatically store the winds aloft
data in a file for use in estimating ground speed and time enroute.

Flight Plan
       This option is used to create and store, or retrieve, a flight plan.

Flight Log
       Flight logs contain information about each leg.  Included are the
VOR frequencies, distance, course, estimates for time enroute, ground
speed, heading, wind correction angle, and other items.

Weight and Balance
       This option can be used to calculate your weight and balance.  After you
enter the weight and arm data, the computer will calculate your gross weight
and center of gravity.

Configure
       Used to supply data about your airplane(s).  The data are stored on
file and are used in many of the other calculations which CAFP  performs.

Data Maintenance
       The DATAFILE contains data on VOR stations in North America. 
If you wish to add, change, or delete data on this file then this option can
be used.  A common use for the Data Maintenance option is for adding 
airport information.  You can also use Data Maintenance to delete  RTE
(route) and PLN (flight plan) files if your disk becomes full.

Select Aircraft
       You may use the Configure option to enter data about more than 
one airplane.  The Select Aircraft option allows you to choose which 
aircraft's data you wish to use for flight planning.

Quit
       This option terminates the CAFP program and returns you to DOS. 
You can also quit by pressing the Esc key.

About CAFP
       Selection of this option displays information about registering CAFP
and data update subscriptions.

     The  remaining sections describe the options in detail.  You should 
work through these in the order presented (not in the order on the Main
Menu) and see how things work.  After that, you will probably not need to
refer to this material very often, but you should keep it handy just in case.

                       Configure


    Select the Configure option from the Main Menu. Using the cursor
movement keys to move around the screen, enter values for your airplane. 
Remember to press the entry key after each item.  If you make a mistake,
press the entry key and type the item again.  If you want to remove or erase
a value, press the space bar then the entry key.

       The aircraft I.D. number is the N-number of your airplane.

       Type/special equipment should be entered as it appears on a
       flight plan.

       The Climb Performance data is vital to the proper functioning of
       CAFP.  There are two columns of values to enter in this area.
       You will need your airplane operating manual to get precise
       values for airspeed and climb rate at the various altitudes.
       It not necessary (or even possible for many airplanes) to enter
       values for all altitudes.  Just enter values up to the maximum
       altitude at which you would ever operate your airplane.  CAFP
       will reject any value for airspeed that is less than 20 knots and
       any value for rate that is less than 100 feet per minute.

       The pilot's name and phone number must be seperated with a "/".
       For example:John Doe/555 555 1234. (No balnks around the "/".)

       The base city and airport must contain the pilot's home address
       and must end with the id of the base airport, for example:
       123 Oak Street, Mytown, MO   STL.  There must be at least one
       blank before the base airport and no blanks following it.

       Color of aircraft should be entered as it apperas on a flight plan.

     When you have completed entering values press the key labeled Esc.  
If you later decide to change any of this data, just return to this screen 
and re-enter the values you want to change.  If you wish to configure more 
than one airplane, then enter a unique I.D. number for each. When you press 
the Esc key, the data will be saved.

At the bottom of this screen (and other screens) you will see "F1 = Help".
This indicates that by pressing the key with "F1" on it you will  receive
information on how to use the current screen.  When finished reading the 
Help information, press the Esc key.
                  Weight and Balance


     Selection of the Weight and Balance option will result in a screen which
is used to determine gross weight and center of gravity.  Using the cursor
movement keys to move around the screen, enter values for your airplane.
Remember to press the entry key after each item.  If you make a mistake,
press the entry key and type the item again.  If you want to remove or erase 
a value, press the space bar then the entry key.

     Refer to your airplane's weight and balance data to enter values on this
screen.  As you enter each value, CAFP will automatically update the
computations.  The value in the box at the bottom of the ARM column  is
the location of the center of gravity.  The value at the bottom  of  the 
WEIGHT column is the gross weight.  You must refer to your airplane's
loading data to determine if these values are within limits.

     The MOMENT column values are computed by multiplying the weight
times the arm.  Traditionally, moment values are recorded as moment
divided by 1000. However, the only reason for dividing by 1000 was to
simplify the arithmetic. Since the computer is doing the arithmetic, we don't
have to  simplify.  The full value is displayed.

     The gross weight is the sum of the values in the WEIGHT column.  
Note that you can enter negative numbers such as for fuel consumed in
Start, taxi and runup.  For entry of the weight of the fuel, if you type  the 
letter g after the number (for example, 80g), CAFP will interpret this to
mean gallons of fuel and will multiply the entered number by 6. For
example, entering 80g will result in a value of 480 (80 x 6) being recorded.

     The center of gravity is calculated by dividing the total MOMENT by 
the gross weight.

     If you want a printed copy of the weight and balance computations, first
make sure the printer is on and ready, then press the key labeled F2.

     Pressing the Esc key will cause all the data on this screen to be saved on
a file (WTBAL.DAT) and you will return to the main menu.  The next time
you use the weight and balance option, all the numbers will re-appear.  To
accomplish a new weight and balance computation, just enter the new
values.
                        Weather

      Now select the Weather option from the main menu.  From the Weather
Menu select option 2 to review the communications settings.

     Option 2 from the Weather Menu takes you to a screen on which you 
may enter communication parameters. 
     1.  COM port
     The communications port value indicates where your modem is
     connected to your computer.  Acceptable values are 1 or 2. If nothing 
     happens when you begin communications (option  1), change this to 2.
     2.  Bits per second
     This is also know as "baud", it is the rate at which data are
     processed by your modem and the on-line system to which you are
     connected.  Your modem must be capable of processing data at the
     rate which you select.  Most modems can process data at 1200 bits
     per second.  If you aren't sure of the proper setting, use 1200.
     3.  Parity
     Parity is a scheme for checking the data to see if it was transmitted     
     without error.  The five allowable values correspond to five different    
     parity schemes known as None, Even, Odd, Space and Mark.  N is actually
     no parity checking.  You should use E unless your on-line system
     instructs you differently.
     4.  Data bits
     This is the number of bits which are used to represent 1 character.  
     It should be 7 for most applications.
     5.  Stop bits
     The number of bits which are used to signal the end of each
     character of data.  Should be 1 for most applications.
     6.  Dialing method
     Use T if you have Tone dialing, otherwise use P for Pulse dialing.
     7.  Telephone number
     The telephone number may be constructed from the digits 0 through 
     9, hyphen "-", parenthesis "(" and ")", and  commas ",".  The  comma
     will cause a pause of 2 seconds and is often used if you have to dial
     a 9 or other digit to get to an outside line and then pause before
     continuing with the dialing.  For example, to dial 9 then wait 4      
     seconds then dial 1 (800) 767-9989 you would enter the following:
                   9,,1 (800) 767-9989.
     8.  Modem Commands
     You may leave this item blank.  If you are familiar with the "AT" command 
     set for controlling modems, you may enter them in this area.  For example,
     to turn the speaker on until carrier detected, enter M1.
     9.  Access code
     You may leave this item blank.  If you want to be logged on to DUAT
     automatically without having to enter your access code, then enter it here.
     10.  Password
     You may leave this item blank.  If you want your password to be
     automatically entered when you log on to DUAT, then inter it here.  Note
     that the automatic entry of password must be used with the above,
     automatic entry of access code.

     After setting the communication values, you may select option 1 to
communicate with DUAT.  There is a five second delay as the program
resets your modem, then it will dial the number you have entered on the
previous screen.  Seven function keys are defined on this screen.  F1 is the 
standard help key.  F2 works as a switch to turn printing on and  off.  F3 is 
also a switch to stop or start saving the session to disk.  F4 may be pressed 
to pause the transmission of data. Press it again to resume transmission.  F5 
must be pressed to exit the on-line system.  It frees your phone line and 
returns you to the weather menu.  F6 is used to send a BREAK signal to the
on-line system.  F7 will prompt you to enter the name of a filght plan 
which will then be automatically retrieved and sent to DUAT.

     Option 3 from the Weather Menu will present a screen for entry of the
winds aloft data.  Winds aloft data are used by CAFP in computing 
estimated ground speed, wind correction angle, and time enroute. The
accuracy of winds aloft will directly affect the accuracy of these
computations.  It is important that you enter current winds aloft data when
flight planning.  Use the cursor movement keys to move around the screen.  
Enter values by typing numbers and the entry key.  If you make a mistake, 
press the entry key and type the item again.  If you want to remove or erase 
a value, press the delete key.

     You must enter two sets of winds aloft values.  The reporting stations
should be selected to be as near as possible to your departure point and
your destination.  The wind direction values are entered in the "from"
column.  Use the full number for wind direction, not the one or two digit 
abbreviation found in winds aloft forecasts.  CAFP will reject any direction 
value less than zero or greater than 360.  The wind velocity value is entered
in the "at" column.  It is not necessary to enter values for all altitudes. You
must enter values up to the first altitude that is greater than or equal to the
altitude you will be flying.  (Subject of course to reporting limitations.  Not
every station will report 3,000 or 6,000 feet winds.)  For example, if the 
highest altitude you would fly is 10,000, you should enter winds aloft for 3, 
6, 9, and 12 thousand.  

     On short flights it may not be feasible to obtain two sets of winds aloft
data.  In such a case enter the data in the Departure columns and copy it 
to the Destination columns.  The copying is done automatically if you press 
the key labeled F3.  In no case should you leave the Destination column
blank.  If you do, CAFP will assume that winds are calm at all altitudes at 
your destination.  This will cause errors in the estimates for wind correction
angle, ground speed, and time enroute, unless the winds truly are calm.

     If you want a printed copy of the winds aloft to take with you, press the
F2 key.  Make sure the printer is on and ready before pressing F2.  The F4
key is used to clear or erase the entire screen.  Pressing F5 will cause the
departure and destination data to be exchanged.  This is useful for planning
the return trip when you expect no significant change in winds aloft.

     After you have entered all the necessary winds aloft data, press the Esc
key.  This will cause the data to be saved on a file (WEATHER.DAT) and 
you will be returned to the main menu.  The next time you select the 
Weather option the same data will re-appear.

     Option 4 from the Weather Menu will cause the weather data file
(assuming you have saved data to your disk while you were on-line) to be 
scanned for winds aloft data.  If any data are found, you may select the data
and it will be automatically entered into CAFP as if you had manually
entered it.

     Option 5 of the Weather Menu can be used to look at the weather  data
file.  (Again, assuming you have saved data to your disk while on-line).  
You may use the PgUp and PgDn keys to move through the file a screen at 
a time.  You may use the up and down arrows to move through the file one
line at a time.  The Home key will return you to the beginning of the
weather data file.

     Option 6 of the Weather Menu is used to print the weather data file. 
(Assuming you have saved data to disk.)

     Finally, option 7 from the Weather Menu will return you to the Main Menu. 
You may also return to the Main Menu by pressing the Esc key.
                         Route

    A route consists of a sequence of facilities that includes at a minimum
a departure point and a destination point.  If you are navigating directly 
from the origin to the destination, then no more facilities are required to 
define the route.  A facility can be any of the approximately 1000 VOR
stations that are in the data file or any other point for which you know its 
latitude and longitude or its radial and distance from a VOR.  If you are 
not navigating directly, then you will want to include some facilities between
the origin and destination.  These are typically a sequence of VOR stations. 
There are three approaches that can be used:  You can let CAFP select the 
sequence automatically, you can specify the sequence yourself, or you can use 
a combination of the two.  To retrieve a previously created route enter its 
origin and destination, or press the Page Down key and a list of routes will
appear from which you may select one.


Automatic route selection

     Assume you wish to create a route from Memphis Airport to New 
Orleans.  Select the Route optioncfrom the main menu.  The route screen will
appear.  The identifier for Memphis Airport is MEM, so  enter it as MEMA. 
Id's can be entered in upper or lower case.  Enter MEMA and you will
receive a message that MEMA is not found.  To add it to the file answer yes 
to the question by typing a y and pressing the entry key.  You will then be 
asked for the elevation, magnetic variation, and either the latitude and 
longitude or its distance and radial from a VOR station.  When entering  
latitude and longitude, give degrees and minutes separated by a colon or 
semicolon or hyphen.  (The data for Memphis is:Elevation=332, Magnetic 
variation=-4.4, Latitude=35-12.1, Longitude=90-3.1)  The data will be added
to the data file. It will not have to be entered again.

     Move the block cursor to the area after the word DESTINATION and 
enter the id MSYA for Moisant Airport.  Answer y and enter the following:
Elevation=4, Magnetic variation=-6, Latitude=29-59.6,Longitude=90-15.4

     The  two  areas  labeled Include and Exclude are used to  enter  id's 
of facilities you want included in the route or that are not to be used in
constructing your route.  We won't use them for now.

     You now have a choice of which method is to be used for constructing 
the route.  Direct routing will cause the route to consist of the origin, any
facilities you specified in the Include area , and the destination.  Since you
didn't specify any id codes to include, if Direct routing is selected you would
have a route that consists of one leg from the origin to the destination. 
VOR routing will cause CAFP to search for a sequence  of  VOR's that will
take you to your destination.  Select VOR routing by pressing F3.  After
the sequence is determined the station id's and distance between them will
appear on the screen.  The sequence will also be stored in a file named
MEMAMSYA.RTE.


Manual route selection

     If you would prefer to specify all the facilities to comprise a route, then
list them in the Include area.  Remember that terminal class VOR's end
with the letter "T".  Choose Direct routing by pressing the F4 key.  The
route will then be created using the facilities whose id's you have entered
and in the same order you entered them. 


Combining manual and automatic route selection

     The third method of defining a route is to combine the two previous
methods.  If there are some facilities you wish to fly over, specify them in
the  Include  area.  Then choose VOR routing (F3).  CAFP will use all of 
the facilities you have specified and will fill in any gaps with VOR's of its 
own choosing. 

     After a route is created you may create another by making any desired
changes to the origin, destination, include and exclude lists and  pressing
either the F3 or the F4 key. If you change a route you have  previously
created, then the new version of the route will replace the old version.

The F5 key is used to create more room for entry of id's in the Include and
Exclude lists.


Maps

     After creating a route, you may press the F7 key to create a graphic
display of your route.  This assumes you have a graphics monitor.  The
display will contain a map of state borders along with a depiction of the
route.  Weather radar data will be displayed (if you have previously saved
the data from a DUAT briefing) by pressing the "W" key.  Additional keys
and a guide to interpreting the radar data may be obtained by pressing the
F1 key. 


                      Flight Plan

   Selection of Flight Plan from the main menu will result in a screen like
the standard flight plan form used by the FAA.  The purpose of the Flight
Plan option is to allow you to create and store flight plans.  Then when you 
need to fly the same route again, the flight plan can be easily retrieved .  
Before creating a flight plan you must first create route of flight.  The Route
selection is used for this purpose.

     The cursor will initially be positioned on the area following the word
ROUTE.  If a route file has been used before selection of the Flight  Plan
option, then the name of that route file will appear here and the route  will
be displayed in the area following.  You may change the route file name by
typing a new name in this area.  If a route or flight plan has been previously
created under this new name, then it will be retrieved.  Flight plans can also
be retrieved by pressing the Page Down key.

     The flight plan form is filled in as completely as possible by CAFP using
data which has been stored on the configuration file, and a route file or a
flight plan file.  Items which are blank will need to be filled in to complete
the flight plan.

              1. Type - Enter an "x" in either the VFR or IFR box.  

              2.  Aircraft Ident. - Copied from the configuration file.

              3.  Type and Special Equipment - Copied from the
              configuration file.

              4.  True Airspeed - Enter the cruising true airspeed in knots.

              5. Depart. Point - Enter the id for your departure point.

              6.  Depart Time - You may enter the time in standard format 
              for universal coordinated time (zulu), or enter the local time 
              and follow it with letters corresponding to your time zone.  
              The second method will result in the time being automatically 
              converted to zulu.  For example,enter 1000cd (for 10 am 
              central daylight) and the resulting value is 1500.

              7.  Cruising Altitude - Enter the cruising altitude in feet.

              8.  Route of flight from - The route of flight will be selected 
              from a previously created route by entering the route name.  
              A route name consists of a four letter origin code and four 
              letter destination code.  For example, entering "memamsya" would 
              cause CAFP to look for a route file for a route from the 
              Memphis airport to the New Orleans airport.  If it doesn't 
              exist then your entry will be ignored. The route of flight can 
              also be selected from a previously stored flight plan.  In this 
              case all the flight plan data will appear on the screen.  Note 
              there is blank space between each facility listed in the route 
              area of the flight plan. If you are creating a flight plan for the 
              first time, then you will need to enter either airway names (for 
              example, V-9) or leave it blank if there is no airway and you are 
              flying direct between facilities.


              9.  Destination - Enter the four letter id code for the destination.

              10.  Est. Time Enroute - This value is automatically computed 
              and entered as soon as you have entered True Airspeed, Cruising 
              Altitude, and distance.

              11.  Remarks - Anything can be entered in this area.

              12.  Fuel on Board - Enter the hours and minutes of fuel on board.

              13.  Alternate Airport(s) - Enter one or two id's for alternates.

              14.  Pilot's Name etc. - Copied from the configuration file.

              15.  Number Aboard - Enter the number.

              16.  Color of Aircraft - Copied from the configuration file.

              CLOSE WITH - Enter the name of the station

     You can experiment with different altitudes to see the affect on time
enroute by simply entering different altitude values in the Cruising  Altitude
box.  Time enroute will be automatically recalculated.  Selection of a
cruising altitude will involve considerations other than time enroute.   CAFP
does not know the suitability of a particular altitude for conducting a flight.
You will have to incorporate your knowledge of terrain, weather, controlled
and restricted airspace, navaid availability, air traffic control procedures,
airplane performance and other considerations to select an altitude for
conducting your flight.

     Time enroute will also be automatically recalculated when you enter
different values for true airspeed.

     After you have completed the flight plan, press the Esc key.  CAFP will
examine the route of flight and perform a "compression" if necessary. 
Compression means the deletion of unnecessary legs on the flight  plan.  For
example if you had V-99 ABCV V-99 DEFV V-99 XYZV for  the route,
then compression  would result in V-99 XYZV.  Next, the flight plan will
be stored in a flight plan file whose name consists of the four  letter
departure point id, the four letter destination id, and the letters "PLN".

     In summary, to retrieve a previously saved flight plan, enter the name
in the area following the word ROUTE or press Page Down and select the name
from the list which appears. The list can be shortened by typing the first 
few letters of the name you wish to use.  The name of a flight plan consists
of the four letter origin id and the four letter destination id.  To create  a 
new flight plan enter a route file name after the word ROUTE or select the
name after pressing Page Down.  Then complete the entry of the remaining 
items on the flight plan.  When you press the Esc key the flight plan will 
be saved on a file and you will return to the main menu.
                      Flight Log

    A flight log is a report which lists each leg of a route and gives useful
information for flying the route.  Included in flight logs are the frequency
of navaids, elevation of airports, magnetic course, wind correction angle,
distance, and estimates of time and ground speed for each leg.  All flight 
logs are based on a route.  So, before you can use the Flight Log option, 
you must first create a route file with the Route option.

     When you select the Flight Log option, you should first enter the name
of the route.  If you have previously used a route name (in either the Route
option or the Flight Plan option) it will appear here automatically. If the
name is correct, you do not need to re-type it.  If the name is not  correct,
then enter the route name using the usual convention of the four letter
origin name followed by the four letter destination name.  You may also press
the Page Down key to receive a list of route names to select.

     In order for CAFP to complete the flight log, it must know your 
altitude and true airspeed.  As before, if you have already specified an 
altitude and/or true airspeed, these values will appear automatically.  If you
wish to change the values then enter a different value.  After entry of all 
three values, the flight log will be displayed.  Note that the total time may
not be exactly the same as the total of the individual leg times.  This is 
because the leg times are rounded to the nearest minute, but the total time
does not have this rounding error.  So don't be alarmed if the total is
different by a few minutes.

     You may, at your option, have latitude and longitude of all waypoints
printed on the flight log.  Start CAFP with the command:  cafp l
 
                    Select Aircraft

            The Configure option will allow you to enter data about  different
aircraft.  Each set of configuration data is stored in a file whose  name is
formed from the aircraft I.D. (N-number).  However, at any given time
CAFP is using only one set of data.  The Select Aircraft option will  allow
you to specify the I.D. or N-number of the aircraft you wish to use.  This
will cause CAFP to load the configuration data for that aircraft.  The Main
Menu will always display the I.D. or N-number of the aircraft that is 
currently selected.  The N-number also appears on the Flight Log screen.





                   Data Maintenance

            The Data Maintenance option allows you to make changes to the 
primary data file and to delete the files that are created when you create
routes and flight plans.  Selection of this option results in a menu. The first
three items allow you to display, delete , and add data to the primary  data 
file. Item 4 is used to delete route files and flight plan files.  Item 5 will
return you to the main menu, as will pressing the Esc key.

     The primary data file as it is delivered contains information about VOR
stations in North America.  You may display information about any of these
facilities or any others that you add to the file by selecting item 1.

     Selection of item 2 will allow you to delete data in the primary data file.
In addition to the over 1000 VOR stations, there is room in this file for
about 700 additional facilities.  If you have added data and you decide to
remove it, then you can use item 2.

     Item 3 is used to add data to the file.  To add a new facility you will
need to supply its name, frequency or elevation, latitude, longitude, and
magnetic variation.  Frequency should be specified for a navigation facility,
elevation for an airport.

     Item 4 allows you to delete route files and/or flight plan files.
