Sideslip
The sideslip is usually used during approach to landing with airspeed 120 IAS / 65 KIAS and flaps in position
FLAPS 2
.
During the sideslip maneuver the fuel in the fuel tanks shifts laterally. In the fuel tank that is lower during the sideslip,
the fuel shifts towards the wingtip and drains from the fuel outlet at the root rib (Fig. 4-2, A). In the case of prolonged
side slip, when the fuel selector is set to the lower fuel tank, there is a potential risk of fuel shortage. The fuel shortage
may cause the engine to stop. Therefore, the fuel tank, which is higher, must be always selected during the sideslip.
Fig. 4-2 Shifting of fuel in the fuel tanks during sideslip
WARNING
In a prolonged sideslip, the fuel in the lower wing tank will shift
towards the wingtip and may cause fuel shortage to the engine!
Even short-term fuel shortage may cause the engine to stop
immediately!
In a sideslip, always set the higher wing tank on the fuel selector!
(e.g. LEFT SLIP
1
=> RIGHT TANK, RIGHT SLIP
2
=> LEFT TANK)
1
left aileron, right rudder
2
right aileron, left rudder
Using engine power during slip / skid conditions may induce an oscillating regime known as Dutch roll. For recovery
from a Dutch roll the following procedure should be used:
a.
Rudder control
Slightly decrease rudder deflection
b.
Aileron control
Keep deflected
After the oscillations have stopped:
c.
Sideslip
Continue or recover normal flight
CAUTION
Using power setting other than IDLE at sideslip may cause
an oscillation known as a Dutch roll! It is prohibited to perform
sideslip with the power setting other than IDLE!
NOTE
If the Dutch roll has occurred, only slight decrease of rudder
deflection is required to recover. Sideslip may be continued
normally afterwards.
