Final answer:
A standard left-hand traffic circuit is typically flown at 1,000 ft AAE for non-jet aircraft, subject to local regulations.
Step-by-step explanation:
The question relates to the altitude at which a standard left-hand traffic circuit pattern is flown. In aviation, a standard left-hand traffic circuit is typically flown at 1,000 feet above aerodrome elevation (AAE) in the case of non-jet aircraft, unless otherwise specified by local airport regulations. It's important to check the specific airport's AIP (Aeronautical Information Publication) or consult with the local control tower to confirm the appropriate altitude for the circuit as it can vary.
