5. BATTERY DISCONNECT SWITCH. The Battery switch has two positions: ON and OFF. When
set to ON, battery power is supplied to the electrical system. When set to OFF, battery power is not
provided. The switch should be set to OFF when external power is used for starting, to conserve the
battery. Whenever the engine is running and external power is disconnected, the switch should be
set in the ON position.
6. GUN HEAT SWITCH. The Gun Heat switch is used to enable or disable power to the electrical
heaters installed on the cover plate of each gun. Gun Heat should remain on whenever flight
conditions necessitate.
7. PITOT HEAT SWITCH. The Pitot Heat switch is used to enable or disable power to the electrical
heater of the pitot tube. Pitot heat should remain on whenever flight conditions necessitate. Pitot
heat should be set to OFF on the ground, as not enough air flow is present to cool the heater and
prevent overheating.
8. POSITION LIGHTS. The Wing and Tail Position Lights switches control the position lights located
on the wing and tail of the aircraft. Each switch has three possible positions: OFF, DIM, and BRIGHT.
