### Handling notes

#### Before taxi

Engine starting sequence is 3-4-2-1

#### Taxi

Normally two engines are used for taxiing. Throttle back, press E23 to select engines 2 and 3, and start taxiing.

Elevator trim 1.0 degrees up is useful, but not essential.
Landing lights: Extend and on.

#### Takeoff and initial climb(fully loaded)

Full throttle and RPM. Press F2 a few times to set engine torque to 815 PSI.
Rotate at 125 kts.
Retract undercarriage
At 150 KIAS, 500 ft AGL: Retract flaps.
Engine torque 780 PSI
Propeller RPM 920
Accelerate to 180 KIAS

#### En route climb

Climb speed around 180 KIAS.
Engine torque max. 780 PSI
Propeller RPM 850-920

#### Cruise

Max cruise: Engine torque 780 PSI, Propeller RPM 850-920.
Normal cruise at full load: 88% compressor rpm (ca 700 PSI), PRPM 850-920, altitude FL200-FL210.

Long range cruise: Reduce torque gradually to hold a pitch of 0 degrees (Watch the autopilot pitch knob or the elevator trim wheels), airspeed around 200-220 KIAS at altitude.

On long flights, use a step-climb technique. Increase altitude by 2000 ft. every two hours or so.

#### Descent

Vertical speed -1200 to -1500 fpm.

#### Holding

Reduce speed to less than 210 KIAS
Flaps 15 degress
Reduce speed to 160 KIAS

#### Approach and landing

Nearing glideslope: Extend undercarriage, flaps 30 degrees.
Reduce speed to 140 KIAS

Glideslope
Reduce speed to 130 KIAS.
At 1000 ft AGL: Full flaps (45 degrees).

After touchdown:
Propellers fully fine (CTRL+F4)
Apply brakes
Retract flaps
Reverse thrust can be used if the runway is short (press and hold F2)
