Section VII
OPTIONAL SYSTEMS
This section contains a description, operating procedures, and per-
formance data (when applicable) for some of the optional equipment which
may be installed in your Cessna. Owner's Manual Supplements are provided
to cover operation of other optional equipment systems when installed in your
airplane. Contact your Cessna Dealer for a complete list of available optional
equipment.
LONG RANGE FUEL TANKS
Special wings with long range fuel tanks are available to replace the
standard wings and fuel tanks for greater endurance and range. When these
tanks are installed, the total usable fuel for all flight conditions is 48 gallons.
COLD WEATHER EQUIPMENT
WINTERIZATION KIT.
For continuous operation in temperatures consistently below 20°F, the
Cessna winterization kit, available from your Cessna Dealer, should be
installed to improve engine operation. The kit consists of two baffles which
attach to the engine air intakes in the cowling, and insulation for the
crankcase breather line. Once installed, the crank-case breather insulation
is approved for permanent use in both cold and hot weather.
