Lots of interesting things here to talk about
someone said the flaps would come off
if no one was flying, maybe they would not be down and less likely to come off?
about the ELT and switching it on as part of a checklist. How about also having the ELT on a timer, set before ENGINE START based on amount of fuel/estimated time to dry tanks at presumed fuel burn rate.
eg: 7 hours of fuel on board, set timer for 6 plus 45. And ELT will start transmitting with fifteen minutes of fuel left.
And the ELT timer would be reset to neutral/off during the after shutdown checklist.
In this way, "G" forces would not be the sole determining factor for transmission. Also remember that if the plane is still airborne, the ELT will transmit farther (ref terrestrial receivers)
