The quality of instructors and people who want to become instructors seems to be decaying rapidly IMHO. There seems to be loads of young men around my local airfield (in the south) who are either in the process of becoming instructors or are actually instructors themselves. They seem little bothered about teaching people to fly and seem to know very little themselves.. perhaps not anymore than those they are teaching.
All that these men have done is obtainined the right qualifications, and then due to not having any luck in the airline employment sector gone and got themselves instructor ratings- "as thats the next box to tick!"
It would transpire that most havent even thought what instructing entails. Seems very poor to me.
