I've never had one yet & not looking forward to it.
There are three scenarios here, a "flight idle" PFL, a "windmilling" fuel/carb ice stoppage & a stopped prop / siezure. I would think the usually taught idle PFL is the least like the real thing, in the first place you are taught to "warm" the engine every 500ft, very useful just when you need a bit of thrust! 2 you are reasonably sure it will go when you need it when you realise the field isn't big enough, 3 you "know!!" the exercise does not involve an actual landing, 4 you knew it was going to happen.
The windmilling prop must produce the most drag, think gyroplanes, how many helicopter pilots have been in autorotation going up? next is the stopped prop/plank, feathered blades may help but I don't have those.
Assured success seems to be more a case of location, location, location.
So, perhaps I should stay in the circuit & practice glide approaches.
Well done everyone who are still able to tell us about theirs.
