External load VNE
while doing recurrent training the discussion of external load VNE came up. the 350 has a VNE of 80 knots. up until yesterday i had always been under the impression that this was to keep the empty longline out of the tail rotor. a very exprienced training pilot stated that it would be very difficult to get the LL in the t/r at even higher speeds. he stated that in bell products with the semi-rigid rotor system, there is a limit due to "mast bending" which is hard on the m/r transmission (as one would guess, given the name).
any thoughts on why the 350 for example, has an external load VNE?
