NOTE: On all issues of engine operation see Rotax engine Operator's Manual.
Follow its instructions to ensure safe and efficient operation of the engine.
2.7 Kinds of operation limits
This aircraft is approved for flying day and night, VFR, simple meteorological conditions.
Flight into icing conditions is prohibited.
2.8 Crosswind limitation
Maximum crosswind component for A-32 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.
