I said play it by ear and I meant it. So, here you go. YOU takeoff in a twinjet and both an engine failure happens and you happened to forget to remove the gear pins and YOU CANNOT retract the gear.
Do you open up your emergency checklist and follow the ENGINE OUT GEAR UNABLE TO RETRACT PROCEDURE ...TAKEOFF
(lots of luck)
Or do you figure something out right away?
Beirut pilot. I have a feeling you think we keep the gear down to cool things off all the time. Like I mentioned, if you were in the pattern doing multiple landings, full stop with brakes as in a training situation, even DP Davies, the brilliant author of "HANDLING THE BIG JETS" indicates you might keep the gear down to cool it off in the traffic pattern.
But as others have indicated, you wouldn't leave the gate, or the ground if you knew the brakes were "TOO HOT"".
IF you had rejected a takeoff and the brakes were HOT, there is a brake cooling schedule provided to the pilot to allow the brakes to cool down PRIOR to another takeoff attempt. THE idea is that on the next takeoff attempt you might have to REJECT that takeoff too. And you need the brakes cool in order to achieve stopping distance. Some types of brakes are less in need of cooling, but that is each type of plane to consider and not a generality.
So, again, we rarely if ever do what you think we do. Training is the only situation you might consider to leave the gear down (mind you, if there is an overheat or fire in the wheel well you might need to lower the gear, but that is a different animal)>
good luck
