4. Voltage high – REMOVE battery charge fuse and FOLLOW PRECAUTIONARY LANDING
procedure, see section 4.2.6 .
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
section 4.2.6 .
4.2.15 Loss of primary instruments
4.2.15.1ASI 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 4.2.6 .
4.2.15.2Altimeter, 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.
