Got a reference for his book Meikleour please.
Tugged in a Rally at a special french site..landing up slope down wind with lots of power (thermal shock engine shock protection and specific rpm as lycoming), full flaps and slats with variable additional drag using side slip to the flare.
F100 used fixed power with variable air brake.
The 17m Phoebus C had the airbrakes mounted too far back which led to either side slipping or a novel trick of varying the approach speed ten knots below recommended when they became more efficient but accelerating just before flare height.
Problem with the BEA procedure was in turbulence with a sluggish analogue auto throttle on the back side of the drag curve and a power pitch change albeit minor and not being able to feel the movement of the levers it led to an ugly helter skelter approach profile. No wonder we had to be fully stabilised (joke) from 3 grand..
