PS-POH-1-1-11 SECTION 4

NORMAL PROCEDURES

Date: 2012-07-03

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 2,000 to

2,200 rpm.
