I introduce PFLS before letting my students go solo and then do two/three glide approaches from various parts of the circuit to various parts of the airfield. To my mind this achieves the following:
- Vital actions are carried out eg. fuel pump on, change carb heat setting, change tank all of which can be achieved easily by the average student whilst pitching for best glide speed - All of these may resolve the problem
- Breaks the link that I must land on the specified runway rather than the largest clear space I can reach.
Personally I think EFATO introduces more fear panic overload to students than PFLs. Certainly does on biennials
