What format do the regional trophies take now? There used to be a spot landing competition with 3 pilots from each squadron, a LL navex with a recce task and a TOT at base, and an individual aeros competition. The aeros used to be done at low level, then it was bumped up to 5000ft, then it was replaced with a precision formation competition, then it came back again, but assessed by an instructor flying with you rather than from the ground.
They stopped, as far as I was aware, when the Tutor came in due to a lack of hours for it.
