BK117
The BK117 variants, whilst being superb all-round helicopters have a couple of very nasty vices which can/have caused accidents or messed flightsuits (to say the least). In particular, the severe pitch-up at high DA/AUW/IAS combinations, and the inability to recover from a steep right roll at sub 40kt airspeeds. Can anyone shed some light on the causes of these and more importantly, are there any plans/mods to have these problems alleviated in later models (EC145)?
Cheers,
The Monkey.
