I am curious...
at non-towered airports the first turn must now be within 300 ft of circuit height
Is there a reference for this? I am aware of the AIP entry to be inserted
ENR 1.1 57.1.4 Pilots remaining in the circuit should climb to within 300FT of circuit height before turning crosswind
from SUP H51/05, but is SHOULD a requirement or a suggestion? Or is there a CAR reference I have missed?
