Back when I was still allowed to fly my PA18, a very very crafty instructor gave me my annual check ride. From 1,500 feet about 8 miles away, the engine performance began to falter - "What are you going to do about it?"
Well I still had PARTIAL POWER, and 1,500 feet, so I decided to continue toward the home field. and as we slowly lost altitude, and as the wind was light, I decided to do a straight in downwind approach and landing. Even though the instructor at this point pulled the throttle back completely, it worked very well. He said later he was sure I would have gone for a circuit to land into wind, so I passed the check ride.
How many instructors in the UK cover the danger of incorrect action when faced with a partial power problem? Is it part of the sylabus?
