It is being discussed as we speak in a parallel thread right here in the Rotorheads Forum:
AS350 Astar/Squirrel
I guess these are in itself serious limitations. At the same time, it seems quite possible for most normal missions to stay within the limited envelope and to never encounter the hydraulics problem. Clearly, Robinson is then not the only helicopter with design-related envelope limitations.
It is interesting to see that while here you say only Robinson had to limit the flight envelope, you are the main contributor to the AS350 limitations related discussion in the "AS350" thread. Both in one day.
I guess what we see here is actually quite normal. I could think of different, specific limitations applying to respective other types of helicopter.
Agree with you - And what about the Bell 407 that also had a number of fatalities and the speed was reduced?? Biased anti - robbie guys should rather open their own thread under the nursery school section....
