[P-51D Mustang]

AIRCRAFT OVERVIEW

The battery is just behind the pilot's armor plate in the radio compartment. The battery and

generator disconnect switches are located on the Electrical Control panel. The generator switch

should be left on at all times when the engine is running. The maximum normal charging rate of the

generator is 100 amperes.

The ammeter should be checked prior to takeoff. Takeoff should not be attempted if the

generator is charging over 50 amperes.

The electrical system controls the emergency fuel pumps, remote compass, pitot heater, gun heaters,

gunsight, radios, carburetor air temperature gauge, coolant temperature gauge, bomb release,

warning lights, circuit breakers, oil dilution system, and IFF destructor controls. The lights controlled

by the electrical system include cockpit lights, the landing light in the left wheel well, recognition

lights installed on the underside of the right wing, and standard navigation lights on the wingtips and

rudder.

Except for the booster coil, which is used only in starting, the ignition system is completely

independent of the electrical system and will continue to function normally in case of electrical

system failure. Ignition power is supplied by the magnetos, the switch for which is on the front

switch panel. The P-51D starter can easily overheat due to the large loads. The starter should not be

used for more than four 20-second attempts to start, with 15-second intervals, followed by a 5-

minute cooling period.

Oxygen System

The oxygen system of the P-51D is a low-pressure, demand-type system. A regulator automatically

provides the correct amount of oxygen required at any altitude. Controls and gauges for the oxygen

system are located in the right front section of the cockpit and include an automatic mixture

regulator, a pressure gauge, and a blinker indicator which opens when the pilot inhales and closes

when the pilot exhales.

The oxygen supply is carried in four tanks installed just aft of the fuselage fuel tank. Two D-2 and

two F-2 tanks are supplied for a total capacity of 3000 cubic in. Normal full pressure of the system is

400 PSI.

Oxygen is flammable! Take every precaution to keep oil, grease, and all such readily

combustible materials well away from any oxygen equipment, including the breathing

mask.
