Messiah. How do you define "thorough training?" Can you quantify the hours required to meet the standard of "thorough training". if a student has been trained to a competent standard then there is little more an instructor can do unless he is the type who is happy to keep on bashing up flying hours at extra cost to the hapless student.

CASA would be interested why your instructor sees fit to teach unusual attitude recoveries at night, particularly with lack of a horizon over water. I suggest that unusual attitude recovery training is best done in daylight VMC because your instructor is sure sticking your neck out doing it at night on instruments. Better still, do it on instruments in a synthetic trainer where extreme attitudes can be attained at no risk. It's cheaper, too!
