GUMPS
GUMPS is a landing checklist based on the KISS principle.
Gas -- On [fullest tank]
Undercarriage -- Down if not welded
Mixture -- Rich
Prop -- Fine [if controllable]
Seatbelts -- Check / remind passengers
I add:
Brakes -- Off
and pull Carb Heat just before reducing power turning base.
These days I start with a reminder to be strapped in to the pax / instructor and on turning downwind do a flow through according to the cockpit layout that covers all the above.
In the flow through I put my hand on each item and look at it while calling out where it should be.
In a Citabria and C-172/152, that ends up as:
Master -- On
Mags -- Both On
Mixture -- Rich
Fuel -- On [both]
Brakes -- Off
Best to say out loud even when solo.
