4.2.13 Inadvertent spin
1. Rudder pedals
– FULLY AGAINST ROTATION.
2. Yoke (Stick)
– PUSH to stops.
3. Rotation stopped
– rudder pedals NEUTRAL.
4. Speed reached 100 km/h (62 mph, 54 kts)
– PULL YOKE (STICK) GENTLY to recover
from diving.
Do not 4g and 229 km/h (142 mph, 124 kts)!
WARNING: Intentional spinning in A-22LS is prohibited!
NOTE: In level flight and during turn stall warning is assured by the aerodynamic
characteristics of A-22LS
– gentle shaking of the airplane and yoke (stick) due to
the starting airflow separation.
4.2.14 Inadvertent icing encounter
1. Abandon icing build-up area.
2. Icing build-up not stopped
– FOLLOW PRECAUTIONARY LANDING procedure, see
4.2.15 Loss of primary instruments
4.2.15.1 ASI failure due to full pressure line blockage
Signs of the blockage
– airspeed indicator reading either:
- does not change with changing airspeed in level flight or,
- reduces during a steady descent or,
- increases during a steady climb.
1. Airspeed indicator readings
– IGNORE.
2. In level flight
– SET THROTTLE to 4000-4500 rpm.
3. Altitude
– MAINTAIN.
4. In descent
– SET THROTTLE to IDLE.
5. Sink rate
– SET to 3 m/s (600 ft/min).
6. Follow PRECAUTIONARY LANDING procedure, see section
4.2.15.2 Altimeter, VSI and ASI failure due to static pressure line blockage
Signs of the blockage:
- altimeter and vertical speed indicator readings do not change with changing altitude or,
- airspeed indicator reading increases during a steady descent or,
- airspeed indicator reading reduces during a steady climb.
1. IGNORE altimeter, VSI and ASI readings.
2. Airplane attitude
– CONTROL by the position of the horizon line with relation to the wings
and engine cowling.
3. Airspeed and vertical speed
– CONTROL using throttle.
