Many years ago with only about 4hrs up my sleeve, I mentioned to my instructor that I had taken the family to Australia's Wonderland the previous day, but they didn't get me to go on the Bush Beast rollercoaster. He replied "I have a cure for that".
Later out in the training area, he got me to climb to 3500 feet, reduce airspeed, pull on first stage of flap and trim for straight and level flight.
The same procedure followed with carby-heat on another couple of times, until we were hanging in the air on full flap at a much reduced speed, and the bugger then threw the flap lever to the floor.
The PA28 dropped like brick with no sky in the windscreen and wings out of level. With a wicked grin on his face, he talked me through restoring it to normal flight, then said "now go and try that roller coaster you chicken". Not quite the lesson I was expecting, but I did learn how much lift the flaps provide.
