Pace, throttle is fully closed most of the time in his method. I think it is the glide method. If so, is this something I need to learn? I am a bit skeptical about it since although it minimizes the risk of not making the field if engine gives, it increases the guesswork (speed) in flare.
With students who have low experience in low powered draggy aircraft methods are taught like pitch for speed which are designed to keep you away from a high drag high AOA situation!
The glide approach does that although I do not agree with the arguments that you can make the field by being high.
More likely you will have a closed throttle and will
Not know that the engine has stopped until
You need it and fixate on landing on
The field .
There are dangers that you will
Be high and fast and land long etch.
The powered approach gives you a more precise landing point and more control
Over the glide approach which is steeper with a more abrupt flare
