180's
Re the " more than 180 degree"comment by SSD I believe its a good idea to deliberately climb out off runway heading ( to the downwind side) so as to only have 180 degrees to get round if the engine fails. Any crosswind component would then compress the turn.
I've tried tight 180's at a sensible height in a Jodel and lost less than 300 ft.
But a Jodel has a light wing loading !
