Speedbrakes related to eng bleed fault
Hello to all, just checking my MEL ATA 35 "engine bleed air supply system", I check that the last condition to dispatch the aircraft is to have all speed brakes operative, I want to understand that is because just in case to loose the other bleed it may take us to perform an emergency descend, (not taking in count apu bleed)....but Im not 100% sure that this is the only reason about the speedbrakes operative in this MEL ITEM.
Any other opinion?
Cheers,
