Jack Stall in FM
After I experienced one in a light B2 (but at 8000ft in a fairly steep level turn) I was unimpressed by the Flight Manual treatment of the issue. As I remember it it said something vague about reducing the severity of the manouvre and all would be well! Seems more serious of a problem than that.
The controls locked for about 3 seconds on me and I was high enough for it not to be a problem. Never had it since in 1200 hours of Squirrel time.
Just a thought, if you're only 3 or 4 seconds away from hitting the trees if the controls lock, you're probably in the wrong place to start with.
I love the B2 for filming work - terrific performance - but it would be nice if Eurocopter upped the hydraulic power and maybe put another rubber band on the drive.
