vmo
hello all
yes u r rite ..
the diff vmo was due wing bending effect and due zero fuel limitation..this was refered to as mode A or mode B ,with a mode a aircraft having a lower zfw lt and also faster.
it was a switch which changed the barber pole on the asi as per the zfw limitation.but whats important here is that some heavier 72s were only mode B but still could to 350 kias or 0.88m.
some 72s which were capable both mode A or B as per zfw ..set mode A or B before choks off and this remained applicable throughout the flight ;implying u cud not change in the air;
i have some time on a mode A plane and have flown it 375 kias in the descent and 350 in climb .. and if i recal correct the pole was sitting at approx 390 knots.
