foz u said a bigger circuit means more people can get in but is that what u really want. 4 in a circuit is enough esp when you have solo students
i think we did 3 - 4 more circuits per detail with the ovals, so you ended up with more movements during a day. but the great thing was you knew were everyone was, same circuit points every time. when someone called final you knew where they were going to be. in a square circuit somone calling finals could still be finishing a cross country!
by the way there was no roll out on the raf oval circuitmain wheels down, full power, go.
the other great bonus was that you could even teach practice forced landings over the same pattern just higher!!! think about it.
the aim of a circuit originally was to stay in the atz, how many can say they are actually doing that with the monster square circuits they fly
