                           Preface

This is my second attempt at a realistic Flight Model,
having been inspired by the popularity of my DC9-31, and my
first attempt at designing with flight shop.  Using the
flight dynamics editor, I have made this aircraft behave as
described in the flight manual.  So you are aware, I am an
Engineer, and an Ex Pilot.   I have flown DC-9, 727, and one
of these days, the 747 simulators.

Thanks to the defunct airline, whose manual contributed all
the specs and operating procedures. The Eastern livery is in
its' memory, since the egomaniacs that ran the union and the
management could not see fit to keep a pioneer in the air.

I apologize for the paint job, but art is not my strongest
subject.

Feel free and drop me a line with your comments, questions
or criticisms.  I do read and respond to all mail.

Turbulent Air Penetration:
M.79 or 285KIAS, whichever is lower.  DO NOT CHASE THE
AIRSPEED.
Note: Below 10,000Ft at Max landing Weight or less, 250KIAS
is applicable.

Maximum Operating Altitude, 35,000Ft

Normal Operations, Description:

NOTE:  IF you have full tanks, you must burn off at least
1,000Lbs of fuel prior to takeoff.  The aircarft is not
certified for flight above gross weights of 121,000Lbs.

1.  TakeOff thrust must not exceed 5 minutes total time.

2.  Normal TakeOff, set flaps at 5deg or 25deg depending on
fuel/passenger load, length of runway.

3.  Apply thrust to accelerate, maintain below 70% N2.  When
airspeed exceeds 40 - 60 Kts, apply takeoff thrust.

4.  At Vr, rotate smoothly to takeoff attitude (5 - 10 deg
nose up).  Confirm positive rate of climb at takeoff.

5.  At 35Ft AFL (Above Field Level), speed should be at V2
to V2 + 10Kts, climb to 1000 AFL at V2 + 10Kts, 20Deg pitch,
raise gear.

6.  At 1000 AFL, reduce pitch attitude by not more than 1/2
(one half) the angle required for V2 + 10Kts to reach 1000
AFL.  Set climb thrust (normally 95% N2.  Maintain climb
gradient while accelerating.  Retract Flaps/Slats on
schedule.

7.  Continue acceleration to Vzf (Zero Flaps)speed.  If Vzf
is reached before 3000Ft, climb at Vzf to 3000Ft.

8.  3000Ft AFL, accelerate to 250Kts, maintain 500-1000
ft/mn rate of climb during acceleration. Climb at 250Kts to
10,000Ft.

9.  Accelerate to climb schedule (290KIAS) past 10,000Ft to
cruising altitude.  Maintain speed until cruise altitude is
reached.

Vzf Schedule:

Flaps Retract V2+25 (5Deg T.O. Flaps)
              V2+35 (15Deg T.O Flaps)

Cruise power is 85% N2 (FAN indicator)

Descent in Range (to landing)

1.   Start Descent at XXX DME.  Target descent rate is 500
Ft/mn to reach assigned level.  To determine XXX, use the
following formula (Altitude (in 1,000's) X 3 = DME distance
to start descent)

Example 1  Cruise altitude 31,000
           DME transmitter on field
                          31 (000)
                         X 3
                         ===
     Start Dexcent at     93 Miles DME

     Cruise Altitude 31,000
     Airport 10 Miles beyond DME transmitter
     From Example 1                 93 Miles DME
     Airport Beyond Transmitter    -10 Miles
                                   ========
     Start Descent at               83 Miles DME

2.  50 miles from the outer marker, level off at 10,000ft
and decelerate to 250KIAS.

3.  Descend at 250KIAS 40 miles from outer marker.

4.  Set 5 Deg Flaps on entering IAP (initial approach
point).  Speed set at 160KIAS.  Descend to MDA (minimum
Descent altitude)

5.  At localizer capture, drop gear, final check list.

6.  At Glideslope + 1 dot, set 25Deg Flap, Speed Vref +
50Kts

7.  At Glideslope capture, Full Flaps, follow glideslope.
Maintain Vref on final.

8.  Land.

9.  After landing, retract flaps, taxi to terminal.

                     Exclusion and legal

The author takes no responsibility for the operation of the
aircraft.  No warranty as to the fitness or merchantability
is expressed or implied.

                            Other

Model Limitations:

1. The DC9-51 has 3 tanks plus an Aux tank.  I took the aux
tank quantity and added it to the main tank.  Flight Sim
only supports 4 fuel tanks.

2.  Fuel consumption is not realistic.  Real jets consume
about 8,000Lbs/Hr per engine at takeoff, between 3,000lbs
and 5,500 Lbs/hr per engine at cruise.  This is a know bug
with Flight Shop.  By flying at 85% FAN, your fuel
consumption will be close to real.

3.  I wish BAO made the landing lights work

4.  The published manual list EPR settings for takeoff,
climb and cruise.  Since there are no EPR gauges in FS5, I
tried to convert to % RPM as best as possible.

5.  Flight sim only gives you 4 notches of Flaps, and no
slat only setting.  The airplane will display slats and
flaps at the same time.

                          Wish List

Any panel designer out there want to work with me on a
realistic panel?
