24 Carrot
Whilst doing my CPL a long while back, an ex military instructor showed me an 'Engine Failure' on finals. He raised the flap and did dive towards the ground to increase speed, which he then used to 'soar' in ground-effect.
Lo-and-behold we did touch down on the threshold.
For good order he then let me fly this, with the same outcome. I was impressed with myself.
Obviously this is non-standard, but might one day save your bacon!!!
