Hello,
I appreciate all your responses. I am only a PPL with limited hours so I still have much to learn. Forgive me if I don't see the obvious but here is the situation I am trying to understand:
Flying on a NAT when simply descending from a cruise at FL350 may not be an option I am curious about a strong head or tail wind that may significantly bleed off speed. If you are flying at M.84 in VNAV and you notice that you are moving down into the stall magin area and the N1 is at the maximum to compensate for the strong winds how do you manage to bring back the speed? I understand that you'd want to put the nose down but how much descent would you be allowed to deviate from your assigned altitude?
Could a strong tail wind be more troublesome than a strong head wind in the situation I've described?
Cheers!
