(Disclaimer: I am not a pilot so my understanding of things may be really broken)
If a plane has lost engine power, has limited altitude to work with, and is upwind of a landing strip, and the pilot doesn't believe she has enough glide range to pass the appropriate runway and turn around for a landing into the wind on the full length of the runway, would it make more sense to
(a) land directly on the full length of the runway, accepting the tailwind
(b) pass part of the runway, turn 180, and land into the wind using only, let's say, half the runway length
Assume that an emergency has been declared, airspace and runway are all cleared, etc. In my particular scenario we're talking about a single-seat, single-engine fighter-type plane with generally poor glide ratio. I'm curious about any contributing factors.
