If we are including the effective teaching techniques..:
During SLMG training (it's a while back), we were climbing out when the CFI said "Engine failure now! Where are you going to go?"
Dithering, thinking too short, too bumpy, too many trees all round, too many solid sheep, too steep.....: "Errr.............................."
"OK then. Where are you going to $£&^!*% crash, then?"
Never forgotten.
