It is all but impossible to get a Lynx with CMRB (BERP Blades) into retreating blade stall - it does 160 kts with ease (212kts max speed record) and shrugs off high G manoeuvering with barely a wobble (2.7 G max permitted for aerobatic manoeuvres but it takes 3 with no problems).

The stick feel/trim can be turned off and leaves you with a heavy, pendulous feeling cyclic (like waving a broomstick with a weight on the bottom)but you still have one of the worlds most responsive helicopters on the other end of it.

96% Nr is not enough to cause the hyds to stop producing enough power but it might trip the gennies off leaving you with no stab. 96% Nr is also not low enough to cause any handling problems in terms of RBS - the flyaway manouvre from the ODM recommends drooping the Nr to below that if memory serves. ISTR the critical Nr for Lynx was about 85%, below which it was very difficult to recover it in flight.

Ronnie - I think you need to check who has asked this question and what Lynx knowledge they have - it may be that they have used a generic helicopter aerodynamics question and applied it to the Lynx without really knowing what the aircraft can do.
