CARGO PACK
FLIGHT OPERATION WITH A CARGO PACK.
All flight characteristics for a cargo pack equipped airplane are iden-
tical to an airplane without a cargo pack. There is, however, a slight per-
formance reduction with the cargo pack installed. This is as follows:

The Cessna Economy Mixture Indicator is an exhaust gas temperature
(EGT) sensing device which visually aids the pilot in obtaining either an
efficient maximum power mixture or a desired cruise mixture. Exhaust
gas temperature varies with cylinder fuel-to-air ratio, power, and RPM.
OPERATING INSTRUCTIONS.
The reference EGT must be known before the EGT indicator can be
used for take-off and climb. Determine the reference EGT periodically
as follows:
(1) Establish 65% power in level flight at 2600 RPM and part throttle.
,
(2) Carefully lean to peak EGT. This is the reference EGT.
NOTE
Operation at peak EGT is not authorized for continuous
operation, except to establish peak EGT for reference
at 75% power or less. Operation on the lean side of
peak EGT or within 25
0
of peak EGT is not approved.
