Pardon the question, but why do the "authorities" believe that knowledge of flight test data is required for a pilot to know how to rotate at Vr and keep a minimum of V2 speed? Our takeoff data cards have two extra remarks: for a field elevation over about 4,000', we add one knot. For temps over about 37* we also add one knot to the airspeed indicator.
Do they actually believe that understanding data from test pilot schools (Edwards AFB/NAS Pax. River) will make us better pilots?
I've only flown transport category turbofans for years and years, and this truly baffles me.
