MJ,
My point is not about the magic of Perf A but the folly about a max 5 degree banked turn in the engine failure situation.
I hoped to get over the point that lowering the nose and aiming for the correct speed (for therein lies the magic) rather than farting around trying to avoid a critical speed is the far safer mindset. And having achieved Vyse, manouvering should not be a problem.
Having achieved Vyse one can assess the performance available and begin to examine your options. Before that time nothing else matters.
