Harrier PFLs
When Boscombe Down were testing the new engine of the GR9 Harrier they had to shut it down in flight and check for relight. Obviously they had to work round the assumption that the engine might not relight. They came to the Wittering simulator and evaluated the possibility of a PFL, to establish the 'key' points in the pattern. I recall that it was dead side at about 15K, turn at the upwind end of the runway and maintain a continuous turn round the pattern. Speed had to be kept up to make the engine windmill at a speed which maintained hydraulics and electrics. In general people could get to the runway but when they slowed in the last mile of the approach the hydraulics and electrics dropped off line and flight could not be maintained.
I recall practicing PFLs in the Gnat and they seemed to work but I don't recall anyone doing one for real and getting away with it. Beagle - any recollections? Glad the OP had a good day in the Hawk sim - it is a fine bit of kit!
