Question 1:
Which of the following actions provide more drag during level flight? I mean, which of the following actions need more engine power to compensate the increased drag?
· Gear down
· Speed brakes
I think gear
You have to land and you need to burn fuel, because you are near the MLW. You are NOT in an emergency situation.
Assuming u done everything during crz to increase fuel burn eg, lower cruise level etc. Start early descend, if atc permits slow down and extend flaps. Depending how much fuel u need to burn, lower gear.
But if u are early and not tight on time...by all means just take up a hold.
I personally don't like the idea of speedbrakes to lose fuel. I only use it if i need to lose height and also
Most aircraft have some warning indication of flying with power against speedbrake
too.
