Islander Vx, Vy, Vxse, Vyse conundrum
I've always understood that Vx & Vy and Vxse & Vyse meet at the absolute ceiling for AEO or 1 inop, respectively. So how is it that a single, 65kts, figure is given for those four speeds even though the aircraft still has a large performance reserve?
Was it a quick & easy way through the certification maze? Something else? If a means of simplifying certification, what are the true figures for those speeds (ISA SL)?
Damned if I can figure it out.
