One of the folks around the hangar took his CFI practical last week. He
had his AGI so they threw out all of the Fundamentals of Instruction stuff
entirely during the oral.

A question the examiner asked him: "You're flying cross-country and trimmed
at 110 knots. You die, and the engine quits. At what airspeed will the
aircraft strike the ground?"

Another was, "You're turning final and you enter a cross-control stall. Is
it better to be in a slip, or a skid?"

I'm wondering what the significance of posting
this question is. Is it because everyone should
know the answer or because on some level it is
nonsensical?

Can't speak for gatt but the I take it for both. There are nonsensical
questions that need to be prepaered for after all its about passing a
test to get to the real learning.
