Navajo on one
is a joke.
2500 hrs on type, and several Cof A renewal flights, with demonstrated s/e climb.
Please do not expect a PA31 to climb on one engine, my procedure is, if slow, then close other engine to permit the crash to be carried out straight ahead.
If some airspeed, then the second engine permits the crash site to be determined, within a 1nm radius....
The C of A renewal, was always a cheat, and the climb performance adjusted to match the published performance. of a NEW aircraft.
DO NOT EXPECT A CLIMB.
