pprune eating Fan#1.5,
The point you so poorly make is that logging flight time is for pilots, and nothing else in the system matters. You are simply wrong.
The logged time becomes the measure of when to overhaul the aircraft, when to inspect it, when to change its expensive parts, how much you pay to insure it, when to tell the pilots to go home and when to scrap it. It is the single biggest measure of how much we spend to operate the machine.
If you change the way you measure flight time by adding the time not flying (stay with me here, this is getting complex) the amount of flight time measured will go up while you carry no more, and go no farther. (Are you still with me?) Time vs productivity is vastly changed.This means the entire system just got more expensive.
I once suggested to Sikorsky that we wire a squat switch on every gear, and log only the actual time in the air. In an experiment, we tracked 5% less flight time using this system. 5% makes or breaks whole markets, prunefan!
