snowfalcon2, HarryMann;
instead of alarming when something is wrong it would report "good to go" if and only if all sensor inputs positively indicate so.
Again, for information only, the "good to go" design philosophy was incorporated into the Airbus A320/A340 series aircraft. Testing the "TOWS", called the "
T.O. CONFIG" is part of the Before Takeoff Check. This system checks the killer items plus a few others:
Slats/Flaps not in takeoff range - Red Warning
Pitch Trim not in takeoff range - Red Warning
Rudder Trim not in takeoff range, (A319, A321) - Red Warning
Speed Brake not retracted - Red Warning
Sidestick Fault - Red Warning
Brakes Hot - Amber warning
Doors - Amber warning
Park Brake ON - Red Warning
Flex Temp not set - Amber Warning
All warnings are accompanied by an auditory warning.
