auxiliary fuel cells as optional equipment. The fuel system on the PA-24-260 has two fuel cells as standard

operates the ailerons and stabilators, and pedals which operate the rudder. Duplicate controls are provided for
the copilot.
1-17. Radio. Provisions for radio installations consist of microphone and headset jacks and mounting
brackets, a loudspeaker, necessary wiring, and panel space for at least four radios.
1-18. Cabin Heater, Defroster, and Fresh Air System. Heater air for the cabin and defroster is obtained
directly from the exhaust system muffler shroud. On the PA-24-180 and PA-24-250 fresh air is obtained
through intakes at the engine cowl, and an air intake at the top of the fuselage providing air to the individual
seats through the air line type overhead vents. On the PA-24-260 and PA-24-400 fresh air is taken from the
leading edge of each wing to the forward portion of the cabin and through an intake located on the dorsal fin
directing air through overhead vents.
1-19. Instrument and AutoPilot Systems. Provisions for instrument installation include panels for engine
instruments and advance flight instruments, as well, as for an AutoPilot system which consists of four
principal parts: a modified directional gyro, a modified gyro horizon, a motor-driven actuator, ind an
amplifier.
