Taxi
Taxing technique does not dier from other taildragging aircrafts. Prior to taxiing it is essential to
check wheel brakes for proper braking action.
In case you expect taxiing to last, take engine warm-up time into account and begin taxiing imme-
diately after engine start-up. Warm-up the engine during taxiing not to cause engine overheating
because of prolonged ground operation.
Holding point
Make sure the temperatures at full power range within operational limits.
Make sure the safety harnesses are fastened and doors closed and secured at all three closing points.
Set aps to 2
nd
position (ap handle full up).
Power idle.
CAUTION! Should the engine start to overheat because of long taxi and holding, shut down
the engine and wait for the engine temperatures drop to reasonable values. If possible, point the
aircraft’s nose towards the wind. This will provide radiators with airow to cool down the engine
faster.
Take-o and initial climb
Before lining-up verify the following:
Spoilers: retracted and secured
Fuel valves: fully open
Fuel quantity: sucient
Safety harnesses: fastened
Cabin doors: closed securely
Trim handle: in neutral position or slightly forward
Flap handle: 2
nd
position (ap handle full up)
Propeller pitch: minimum - at setting (propeller pitch knob screwed to the left fully)
Runway: clear
Now release brakes, line up and add full power.
Verify engine for sucient RPM at full throttle (5300 - 5500 RPM).
CAUTION! Keep adding power gradually.
WARNING! Should engine RPM not reach 5300 - 5500 RPM when at full throttle, ABORT
TAKE-OFF IMMEDIATELY, come to a standstill and verify that the propeller is at minimum pitch
setting.
Start the takeo roll pushing elevator one third forward and lift the tail wheel of the ground as you
accelerate. Reaching V
R
(between 60 -70 km/h; 32-38 kts), gently pull on the stick to get the aircraft
airborne.
CAUTION! Crosswind (max 28 km/h (15 kts)) takeo should be performed with ailerons
deected opposite the direction of the wind. Special attention should be paid to maintaining
runway heading!
