NORMAL PROCEDURES
Date: 2015-11-11
4-6
Rev. No.: 1
CAUTION
•
The starter should be activated for a maximum of 10 sec, followed by 2 min pause
for starter cooling.
•
As soon as engine runs, adjust throttle to achieve smooth running at approx.
2,500 rpm.
•
Check if oil pressure has risen within 10 sec. and monitor oil pressure. Increase
of engine speed is only permitted at steady oil pressure readings above 2 bar.
•
At an engine start with low oil temperature, continue to observe the oil pressure
as it could drop again due to the increased flow resistance in the suction line. The
number of revolutions may be only so far increased that the oil pressure remains
steady.
•
To prevent impact load, start the engine with throttle lever in idle position or
at the most up to 10 % open.
4.2.3 Engine warm up
Prior to engine check block the main wheels using chocks. Initially warm up
the engine to 2,000 rpm for approximately 2 min, then continue to 2,500 rpm
till oil temperature reaches 50 °C. The warm up period depends on ambient
air temperature. Check temperatures and pressures.
4.3 Taxiing
1. Flaps
- retracted (0°)
2. PARKING BRAKE
- release
3. Brakes
- function check at taxiing start
Apply power and brakes as needed. Apply brakes to control movement on
ground. Taxi carefully when wind velocity exceeds 20 knots. Hold the control
stick in neutral position.
NOTE
During the airplane waiting maintain the engine speed within the range from 2,100 to
2,300 rpm.
For hot temperature conditions:
•
Restrict engine running at ground to the shortest time only
•
Avoid or limit taxiing in downwind or
“
wind blowing from the right side
”
position if
possible
•
In case the CT is close to the limit, reduce the temperature by turning the airplane
in a head-wind or
“
wind from the left side
”
position and set rpm to 2,100-2,300
