In my test the examiner had me do a PFL and then as I was zooming away reduced the engine and said "OK now do another one" I was about 100 feet off the ground at the time!
This was of course a well known microlight pilot in a hotter country
Exactly the same thing happened to me whilst doing my PPL skills test! However I wasn't in a hotter country, I was about 10 miles NE of Blackpool in the middle of winter, windy, heavy rain, the examiner was a very old and experienced aerobatic pilot & instructor and a tad crazy - he was shouting at me, basically telling me we were going to die if I didn't get it in that field. A bit unorthodox, but definitely gave me the mental kick I needed! IMO the key method which has always worked for me:
>Trim best glide
>Wind direction - know it
>Pick a suitable field - Stick to it where possible! (Sheep fine, Cows not! Watch out for power lines etc......)
>Tell the instructor / examiner your intended field
>Position downwind ASAP
>"Why has it failed?" & Restart procedure (if 1500ft or above)
>Turn on to base, early if necessary! Better to be high & fast than low and slow or blown out.
>Setup final approach
>Add flap as required - don't be hasty though
>Fly steep S turns if too high
>'Warm' the engine if too low!
>Make sure you get it in that field - fly like your life really does depend on it!
Other advice... don't hesitate, if you change you mind, tell the instructor / examiner immediately. Whatever you do get it in that field!
