after a lot of flying at Bankstown, and all over NSW, i have decided to come up with a more relevant single engine fixed gear aircraft prelanding/downwind check.
1.. seatbelts secure.
2 radio frequency correct
3 correct radio calls made
4. correct runway in use.
5. feet off the brakes.
done.
If you have made it to the downwind/ end of flight phase of your flight, im pretty sure things like gear down and welded, switches on both etc, are pretty much where they should be for landing.
