Evacuate! or, not?
I had a recent sim session with an aborted T/O below V1 (engine fire) when the preferred scenario was, after doing the usual stuff, to wait ten seconds after hitting the firewall shutoff switch for the fire to go out, fire one bottle, wait 30 seconds for the fire to go out, fire the second bottle, wait ten seconds for the fire to go out, and then, and only then, to order an evacuation.
The scenario used to be to just hit the firewall shutoff switch, fire both bottles and evacuate with no particular attention paid to whether the fire had gone out or not.
What is the preferred scenario among other operators, please? I don't have a lot of big airplane experience, coming from a light aircraft, single-pilot background.
My intuition is to just get away from the aircraft and watch from a distance, along with the passengers and crew, of course, to see if it wants to either just sit there or else go up in flames. But, of course, I could be wrong.
