3.7 Kinds of operation limits
This aircraft is approved for flying day and night, VFR, simple meteorological conditions.
Flight into icing conditions is prohibited.
3.8 Crosswind limitation
Maximum crosswind component for A-22LS airplane is 7 m/s (14 kts).
It is highly recommended to choose upwind direction for takeoff and landing with the least
crosswind. It will significantly shorten takeoff and landing distances and increase degree of
safety.
