5.10 DESCENT
Due to position of fuel sensors, during descent fuel gauges in cockpit will indicate a
fuel quantity slightly higher than the real amount. Regaining level flight will immedi-
ately restore correct indications.
1. Mixture control: slowly full rich
2. Propeller lever: as required
3. Throttle: reduce as required
Shock cooling shortens engine life.
When reducing power, the change in cylinder head temperature should not exceed 50°F
per minute. In order to ensure best practice and avoid potential illumination of ALT FAIL
(due to low propeller speed), the following best practice should be observed:
- Reducing power to maintain a minimum descent speed of 84 KIAS (best glide) and /
or a blade angle to maintain 850 RPM;
- Opening the ALTER AIR command to full open (to avoid ice accretion).
CAUTION
The maximum permissible cylinder head temperature (500 °F) must never be exceeded.
The mixture control lever should always be moved slowly.
Before selecting a higher power setting the mixture control lever should, on each occa-
sion, be moved slowly to fully RICH.
Care should always be taken that the cylinders do not cool down too quickly. The cooling
rate should not exceed 50 °F per minute.
