I also teach PFL's down to as low as I can.
I've also had to do a real one (in a PA28-140.. glide characteristics of a breeze block towing a parachute) and can personally attest to practising them as often as possible.(since I'm still here!)
If you can find an area where its safe to go right down to the flare.. all the better.
It seems that by making a fuss over the legality of PFL's and EFATO's the CAA are basically saying that they put the value of life beneath that of "technicalities".. which frankly stinks.
I'll keep teaching my students to fly PFL's properly, competently and safely, and if I ever get prosecuted at least i will be able to hold my head high knowing I've done the right thing.
Sad isnt it
