If the GPWS starts blaring at me, I'm expected to take action now, without thinking about it. Anyone who doesn't can expect to end up dead.
If the TCAS goes off, I'm expected to take action now, without thinking about it. Anyone who doesn't can expect to end up dead.
If ATC tell me " ABC123 Avoiding action, turn hard right NOW", I take action now, without thinking about it. Anyone who doesn't can expect to end up dead.
I've done this. A large turboprop, slung about 60 degrees of bank on and taken it 90 degrees to my previous heading.
Apologise to the pax and give them the explanation later. I am not going to argue the toss with the controller. I do not intend to take part in a large-scale reproduction of Brownian Motion.
Anyone on a Sim check who doesn't sort out a GWPS incident correctly can expect to fail the ride. Perhaps something like this should be done for avoiding action incidents?
