Piper External Power - Piper CHEROKEE CRUISER PA-28-140 Information Manual

CHEROKEE CRUISER
Whenever the throttle is in the full throttle position, it actuates a micro switch which
disengages the compressor and retracts the scoop. This is done to obtain maximum power and
maximum rate of climb. The fan continues to operate and the air will remain cool for
approximately one minute. When the throttle is retarded approximately 114 inch, the clutch
will engage and the scoop will extend, again supplying cool, dry air.
PIPER EXTERNAL POWER*
An optional starting installation known as Piper External Power (PEP) is accessible through
a receptacle located on the right side of the fuselage aft of the wing. An external battery can be
connected to the socket, thus allowing the operator to crank the engine without having to gain
access to the airplane's battery. This installation is not available on the Flite Liner.
