Parking and taxiing:
Check wheel brakes for freezing when parking outside and the temperature is below 0 ° C. Check the wheels are not
obstructed (push/pull the aircraft by hand to ensure free rotation of the wheels) prior to taxiing. Heat the brakes with
the hot air to remove ice. Do not try to remove the ice by braking during taxiing!
CAUTION
Do not try to remove the ice by braking during taxiing!
Coolant:
The water cooling system is originally filled with a coolant mixture protecting the cooling system against freezing up to
temperature -38

C. Check the condition of coolant mixture before winter operation to prevent the failure of the
radiator or cooling system due to ice.
If the outside temperature is below coolant mixture freezing point, the coolant mixture must be drained or renewed
using a pure coolant to gain a lower freezing point. If the entire system must be refilled, refer to the aircraft
maintenance manual. Use only coolant according to the specification stated on the placard in the engine
compartment.
WARNING
Do not replenish the coolant if the engine is hot! Always let the
engine cool down to ambient temperature!
CAUTION
Use only suitable coolant according to the specification stated
on the placard in the engine compartment! Never mix different
types of coolants!
NOTE
For complete coolant specifications see OPERATORS MANUAL FOR
ROTAX ENGINE TYPE 912 SERIES, Doc. No. OM-912 and Rotax
