I solo-ed this morning at 14 hrs 25 mins total hours, which included 8h 55 in a Grob G115 then the remainder in a C172.
Prior to this I too had been put through numerous EFATO scenarios, practice forced landings, glide and flapless approaches and a "what if the field closes while you're in the circuit?"
The spur for my instructor to send me for my checkride prior to the final was the first time I beat him to declaring a go-around!
I can't with the best will in the world see how all this and general handling too can be covered in less than 10 hours, although I do have age against me (>50)
