ELECTRIC

FOOTWARMER HEAT

SYSTEM (COCKPIT)

The electric footwarmer heat system provides

electrical heat from heelplate assemblies in-

stalled on the flightdeck floorboard below

each rudder pedal (Figure 11-12). The elec-

trical assemblies provide heat to the pilot and

copilot rudder pedal areas whenever the flight

compartment temperature drops below 60° F

(15.6° C).

The electrical footwarmer heat system consists

of a circuit breaker, thermostat, and four

heelplate assemblies. Each heelplate consists

of three heater blankets, a heelplate, and as-

sociated wiring. The thermostat is mounted in

a bracket located behind the copilot’s aft kick-

panel. The circuit breaker is located on the

copilot’s circuit breaker panel.

Power is applied through the FOOT WARM

circuit breaker to the thermostat. If the ther-

mostat senses temperatures above 60° F (15.6°

C), the thermostat opens removing electrical

power from the heelplate. Once the thermostat

senses temperatures below 60° F (15.6° C), the

thermostat closes applying power to the

heelplate.
