First thing you would need to know is how often problems are found in these redundant checks. Then what sort of errors are made. I suspect that standardizing payload interfaces alone would fix most of the problems. Needless to say, NASA strongly opposes standard payload interfaces.

Yes, but you then have to know how to disable the burgler alarm timer that is set off by physical damage to the communications facilities. This is very hard unless your spies have sent you the necessary codes. In that case, they most likely have sent you the plans, so why not just destroy it? Doug McDonald ------------------------------ Date: Sat, 17 Nov 90 11:57:41 AST From: LANG <@BITNET.CC.CMU.EDU:LANG@unb.ca> Subject: Combined GPS and MLS System to be Developed To: CANSPACE@unb.ca, Space Digest Mayflower Communications Co., teamed with Bendix Communications Div., will develop a combined Microwave Landing System / Navstar Global Positioning System (MLS/GPS) unit to improve aircraft safety when pilots are flying curved approaches. It is possible to lose MLS contact at some time during a curved approach if the aircraft masks the signal. With the navigation accuracy of GPS and approach paths stored in an on-board computer, the MLS/GPS unit will allow the pilot to continue the approach until the MLS signal is reacquired or to fly to a safe departure route, according to John Brady, Mayflower program manager. The seven-month first phase is to produce the initial system design. During the second phase the companies are to prototype, fabricate, and test two systems. The field and flight tests of the prototype systems will be conducted at the Federal Aviation Agency's Technical Center, Atlantic City, N.J. Formal certification would follow if the FAA is pleased with the results, Triveni Upadhyay, Mayflower's president, said.
