Any of the following could be a hint that your time as an instructor is nearly up:
1. Having cat naps on cross country flights of 3 hour duration.
2. Falling asleep for longer than than 30 mins on the similar flights
3. Getting cat naps in on downwind during circuits at a busy (6 A/C in CCT at a time)aerodrome.
But the real clincher is. . .
4. When the flying school shuts up shop you decide to do a Uni course rather than slog it out with other 'casual' pilots for the then substantial sum of $ 15.00AUD per hour of flight time.
That's when you will know.
