10.8.5 Low speed flight, recognizing the starting and ongoing stall and stall recovery
The aircraft has no adverse handling features at low speeds and at stall with any of flaps
settings. A light vibration of controls in roll may be noticed that warns about approaching to
the stalling speed. The stall occurs in form of airplane pitch angle decrease without a
noticeable change in bank angle. The airplane recovers from stall immediately if the flight
controls are returned to their neutral position. During a low speed flight with wings level
deflection of ailerons does not initiate stall. However during a turn at a low speed abrupt
aileron deflection may cause stall with noticeable increase in bank angle.
Stall recovery procedure is described in the section Error! Reference source not found..

10.8.6 High speed flight, recognizing and recovery from steep diving spiral
The aircraft has no peculiar handling features at high speeds. The control forces increase
with airspeed growing and that impedes the abrupt control inputs and exceeding the limit
loads due to that. During high speed flight the engine parameters must be monitored and
exceeding its operational limits must be prevented.
To recover from a steep spiral the engine RPM must be reduced first and then the airplane
must be brought to level flight by deflecting gently the ailerons and elevator.

10.8.7 Short field take-off and landing with overflying obstacles
Short field takeoff and landing procedures are described in the sections
. To
fly over the obstacles (if any) during the climb and approach it is recommended to set the
flaps to 2
nd
position and fly at the best climb angle speed V
X
= 90 km/h (56 mph, 49 kts).

10.8.8 Crosswind take-off and landing
It is recommended to use 1
st
flap setting during crosswind takeoff or landing.
In case of crosswind takeoff it is necessary to rotate the yoke by 1/3 of its full travel against
the wind direction to counter the downwind drift and control the heading using the rudder
pedals. Then the takeoff will occur with some bank angle. After the takeoff the wings shall
be set level, the downwind drift shall be countered with an appropriate change of heading
and climb shall be continued.
In case of crosswind landing it is recommended to keep the airplane aligned with the
runway using rudder pedals while countering the downwind drift with a bank angle against
the wind direction. The bank angle value shall be appropriate to the crosswind strength.
The bank shall be maintained until touchdown which will occur with one of the main wheels
touching the ground before the other. During the landing roll the nose wheel shall be kept
lifted as long as possible and the heading shall be maintained using the rudder pedals.
Immediately before the nose wheel is finally touching the ground the rudder pedals shall
be set neutral in order to prevent the side load on the nose leg.
