I'm flying VFR circuits at a towered aerodrome, and the circuit is quite busy. With traffic ahead of me to land, the tower calls on the radio and asks me to orbit on downwind. I know it's good airmanship to keep a neat orbit, centred over one point on the ground, but how tight should I make it?
A tight orbit takes up less space (I've known there to be three aircraft all orbiting on downwind at once), but at the same time, it seems like a waste of effort and fuel to be making tight turns the whole time when the point of orbiting is to kill time. A lazy orbit (at say rate 1) would kill time just as effectively while flying at a much more comfortable attitude - and more stable in windy conditions.
