On the P-51D, there is NO ARENS control to prevent accidental raising of gear on the ground.
check controls for freedome of movement.
Fasten safety belt and shoulder straps.
Set altimeter to correct barometric pressure.
Oil and coolant shutters to full OPEN position (switchs full forward) Set trim tabs. Rudder 5? Right, Elevator 2? to 3? Nose UP (with 25 gallons or less in fuselage tank). Elevator 1? to 3? Nose DOWN (fuselage tank full). Aileron 0? for Take-Off.

Fuel booster pump on and check for 8-12 pounds of fuel pressure.
See that prop is clear.
Lift guard on starter switch on pilot's switch panel and press switch to START. Caution in use of starter not to overheat.
As engine starts, move mixture control to AUTO RICH. If engine does not fire, after several turns, continue priming.

Warm engine at approximately 1300 RPM. Check for constant oil pressure. If no oil pressure or low pressure after 30 seconds, shut off engine.
Check all instruments for proper readings.
Check hydraulic system operation by lowering and raising flaps. Loading 800-850 pounds and unloading at 1050-1100 pounds.
Check communication equipment for proper operation.
