A little memory aid that you can use any time you enter the runway for takeoff or exit after landing is "Lights, Camera, Action"
Lights: landing light and strobes
Camera: Transponder to Alt or standby
Action: Mixture, Fuel Pump, doors/windows.
I use ATPL when entering the runway for take off :-
A - Altimeter - double check the correct QNH/QFE is set on all the altimeters.
T- Transponder - alt.
P- Pitot heat - on.
L - Landing/stobe lights - on.
When airborne, landing light off once clear of the circuit.
On the way back in, landing light on entering the ATZ and off during the after landing checks once vacated which then becomes F(A)TPL.
F - Flaps - retract
(A) - miss this one out,
T - Transponder - stby
P - Pitot heat - off
L - Landing/strobe lights - off
Easy to remember too as thats what a lot of people are training for !!.
