"in a Wessex?" I presume you disagree with the CAA on this:
"
- This depends heavily on the yaw stiffness of the aircraft without TR thrust. For example, the Gazelle, Squirrel, Jetranger, Sea King and Wessex are relatively stable, whereas the Lynx and Puma are relatively unstable.
"
Maybe you are right and they are wrong?
"and got the throttles chopped smartly"
chopping the 'throttles' is
normally a really bad idea, lowering the lever does what you need, most of the time, unless you want to lose the RRPM too??
and the Wessex case was
not entirely without warning:
"However, the simulated yaw channel runaway manoeuvre involved the application of considerable sideforce, which with the resultant requirement for higher TR thrust, generated a high load on the tail structure. This caused increased bending forces in the tail boom, which tended to stretch the transmission train, and resulted in the minimal engagement of the disconnect coupling being lost. "
have a nice day.
