3.3 ABNORMAL FLIGHT TEGNIQUES
01 GO-AROUND
The go-around procedure has to be initiated when the approach has to be abandoned.
Make sure to select prop RPM before setting TO PWR
Go-Around requirements:
– Quick and correct power application.
– Stopping of sink rate by proper rotation.
– Speed at least 90-85 kts during the procedure.
If go-around is initiated:
Above 500 ft HAA select CLIMB power (32,5”MAP/2325 RPM)
Between 200-500 ft HAA select METO power (41” MAP/2550 RPM)
Below 200 ft HAA select T/O power (48” MAP/2700 RPM)
Go-around two engines:
PF PNF
• Call: 'GO-AROUND, SET
POWER’
• Rotate to nose up attitude.
• Command when positive rate:
“GEAR UP”
• Set power and
state: ‘POWER SET’
• Monitor procedure and
Rotation.
• Repeat, select confirm
Continue as for Normal Take-off, refer to Part B 2.3.3
Note: - When an engine fails during a go-around maintain a speed of 87 kts IAS min if
sufficient altitude exists accelerate spd 90 kts and climb
Proceed as for ‘engine failure/fire after V1’
02 WAVE-OFF
The wave-off procedure (rejected landing) is similar to the go-around procedure for two
engines except that the maneuver begins with the power levers near or at flight idle and at
altitudes below 50 ft. Continue as a normal Take off and accelerate 90 kts before climb.
Pay special attention to the following aspects:
– Initially rotate only to stop the descent.
– During power application devote full attention to pitch attitude control.
– Do not rotate to a climb attitude until the speed is a minimum of 9805 kts
– Touching of the main wheels on the runway must be expected as it takes
– A few seconds for the engines to deliver take-off power.
Notes: The trim change on applying take-off power is significant but the stick force can be
Held with one hand.
A rapid opening of the power levers create initially a tendency for the propellers to
Fine off with the associated drag
A wave-off during single engine operation is not possible.
