Another consideration is the effect of bank on Vmca which is quite significant.
If the aircraft is at low speed, as it probably would be, then bank into the dead engine will result in an increase in realworld Vmca ... bank too far ..... Vmca increases substantially
Slightly confused by this, John.
From a regulatory point of view, Vmca is defined with a bank limit and presumably the assumption is non-turning flight, so it doesn't make sense to talk about it as a function of bank in a turn. But assuming we forget the bank limit and consider Vmca as simply the lowest speed at which we can retain control...
What's the limiting factor? Do we run out of aileron authority earlier if we turn into the dead engine? Presumably it's not rudder authority. How does bank angle affect it?
