Section 4
Model GA8-TC 320 Normal Procedures
c. Return mixture control to full rich and adjust the RPM and manifold
pressure for desired performance cruise operation.
d. Lean out mixture until TIT is the value established in step (b).
This sets the mixture at best power.
Best Economy Cruise
Lean to peak TIT or 1650°F (899°C), whichever occurs rst
CAUTION
NEVER EXCEED 1650°F (899°C) TIT
Operation of the mixture control should be slow enough to allow for the slight lag in the TIT
gauge. Engine roughness may occur when operating at best economy. If this occurs, enrich the
mixture sufciently to obtain smooth engine operation. Any change in altitude, speed, MAP or
RPM setting requires the TIT to be rechecked and the mixture re-set. The cowl ap should be
set to maintain the CHT and oil temperature within limits, depending on the ight conditions. The
cooling effect of the ambient air decreases with increase in altitude and the cowl ap opening
may therefore need to be increased at high cruise altitudes.
4.4.8 Stalls
In any attitude or under any loading condition the stall is preceded by a slight aerodynamic
buffet. In addition an articial stall warning horn is set to activate 5 to 7 KIAS above the stall
speed in any conguration. All controls are effective up to and completely through the stall and
there is no noticeable tendency to enter a spin after the stall.
4.4.9 Descent
NOTE:
During let down ight the mixture may require adjustment to
obtain smooth engine operation. The mixture may require gradual
enrichment only sufcient to ensure smooth operation.
4.4.10 Approach and Landing
Landings are normally conducted with full aps (38°) and the propeller set to the full ne position.
The landing approach is conventional. Care must be taken to ensure airspeed is accurately
maintained during the nal landing approach. Timely and appropriate use of power should be
exercised to maintain the desired ight path and airspeed. Excessively high approach speeds
will result in prolonged oating and increased landing distance. Normally the throttle should be
fully closed during the ‘are’ to reduce the tendency to oat and prolong the touchdown. The
cowl ap should be opened as part of the nal approach checks to set up for a possible baulked
landing situation. Touchdown should occur on the main wheels initially, followed by the nose gear
which should be held clear of the ground during the initial ground roll. Positive braking may then
be applied depending on requirements and circumstances. For maximum braking effectiveness
the wing aps should be retracted and back pressure applied to the control column.
NOTE:
During descent from cruise altitude to circuit altitude it may be
necessary to adjust the mixture for smooth engine operation. When
landing at higher elevation airports the mixture may need to remain
leaned for smooth engine operation during circuit ight and landing.
Low elevation elds may require that the mixture be moved to “full rich”
in the “before landing check list”
