Interesting how many slight variations there seem to be!
The one I use is on the downwind leg and is:
Brakes - Off
Undercarriage - Down & Locked
Mixture - Set to rich
Prop. Pitch - Set (for cruise i.e. not fine - yet!)
Fuel - Sufficient
Instruments - Set & T's & P's in the green
Carb Heat - On
Hatches & Harnesses - secure
This is followed on finals by CRAPP checks:
Carb Heat - Off
Runway - Check clear
Approach - Good/Corrections required/Go arround!
Prop. Pitch - Set to fine
Permission - Received/Not required
Works for me!
