At my university we used a flow check for all emergency items, and it would also be done as a before landing. HOwever, the actual before landing checklist would also be done on the downwind leg, using the GUMPS check on base and final legs ensure that everything was performed properly.
Floor to the door is what's used on emergency setups here...
Fuel - Both
Shutoff - ON
Mix- Rich
Aux Pump - ON
Master - On
Mags - Both
Engine - Crank
after its done, verify that things have been completed via the actual checklist (if you have time aka. altitude) then move on to your emergency landing.
