PFL's
This thread is only confirming the problem that a low hour PPL has in dealing with a 'real' emergency.
Unlike the military that 'practice' this all the time the civil PPl has to be able to 'do his best' in the circumstances at the time.
His best insurance is BEING AWARE, and that although unlikely it is possible and therefore having a simple game plan 'tucked in his mind' will serve him well.
This has to be based on being at a relatively low altitude, and a possible low annual flying time.
The priority is maintaining control,and focussing on flying the machine down to the best approach. With the luxury of height there is the chance of a quick fuel appraisal before turning it off,but then the 'air restart' situation (probably never ever practiced) for a non aerobatic pilot will take time, and this is when you can start to loose control of the situation.
You have to decide on a system that suits YOU and make it as simple as possible.
