PITOT ANO STATIC SYSTEMS
PITOT SYSTEM

tion of the airspeed indicator. The pitot mast is located on
the leading edge of the left wing.
PITOT HEA T (Optional)
The
pitot mast is provided with an electric heating ele-
ment which is turned on and off with a switch on the in-
strument panel. The switch should be ON when flying in
visible moisture. lt is not advisable to operate the pitot
heating element on the ground except for testing or tor
short intervals of time to remove ice or snow.
NORMAL STATIC AIR SYSTEM
The normal static system provides a source of static air to
the
flight instruments through a flush static fitting on each
side of
the airplane fuselage. Drain moisture accumula-
tions from the system (CD-814 thru CD- 1013) by opening
the access door on the side panel in the rear baggage
compartment and removing the section of rubber hose. On
later models (CD-1014 thru CD-1254), the rear baggage
compartment bulkhead must be removed to gain access to
the drain plug, tocated at the low point of the normal static
system. The closure bulkhead is held in place with Velcro
and may be removed by pulling forward. The system
should be drained every 100 hours and after exposure to
visible moisture, either in the air or on the ground.
