Note: engine fuel return line ONLY dumps to the left tank which means
that while running on the right tank some fuel is transferred to left tank.
This is amount 5liter/h and will cause that the total time on the left tank is
higher than on the right tank.
An illumination of the low fuel caution light indicates that approx. 6liter
are left in the respective tank giving a 15min remaining flight time on the
respective tank.
2. Throttle
-
Set as desired
3. Prop control
-
Set engine speed maximum
5500 RPM
(min 5200 for MAP>29”Hg)
(min 4650 for MAP>27”Hg)
4. Fuel flow
-
Check
NOTE
The throttle and propeller control levers are located on the quadrant
between the seats. Their position is held by a friction system. Failure of
the friction system or creeping control setting warrants according
maintenance action.
Refer to Section 5, for recommended cruising regimes.
4.4.11 Descent
1. Throttle
-
Reduce (15...17
”Hg)
2. Prop control
-
Set engine speed maximum
5000 RPM
3. Airspeed
-
Set (90..100KIAS)
CAUTION
It is not advisable to reduce the engine throttle control lever to minimum
when descending from very high altitude. In such cases the engine
temperatures get too low and a loss of power may occur. Descent at
15..to 17inHg manifold pressure and airspeed of 90KIAS to 100KIAS
results in approximately 500ft/min descent
CAUTION
Descending for extended periods of time at higher RPM can lead to
exceeding EGT maximum limit. Reduce RPM accordingly.
