Cross wind take off
The Europa has quite a small, round, rear fuselage, a fairly small fin, and a
powerful rudder. It also has a very powerful all-flying tailplane, which
allows the design to be such that the tailwheel has a greater percentage of
the total weight than would be possible with many other tailwheel aircraft
which have fixed tailplanes and elevators.
Since the tailwheel is steered directly by the rudder pedals, this weight is of
benefit when carrying out cross wind take-offs. The benefit is obviously
reduced when the aircraft is loaded to a forward c of g, i.e. no baggage or
low fuel.
The cross wind limit of the aircraft is 15 kts. With the Rotax engine fitted,
which turns the propeller clockwise as viewed from the cockpit, the effect
of engine torque, the rotating prop wash and gyroscopic precession of the
propeller makes a cross-wind from the port side the worst case. If the wind
is at 90° to the runway, take off with the wind from the right.
Hold sufficient aft stick in the early part of the take-off run to keep the tail
wheel firmly on the ground to give positive directional control, and start
with full into wind aileron. Hold full into wind aileron until you are sure
you have full aileron authority.
In order to obtain the maximum benefit from the direct tailwheel steering,
you should delay lifting the tail until close to, or in very gusty conditions,
right up to, lift off speed.
A good rule of thumb is that once the ailerons have sufficient power to lift
the down wind wing up off its outrigger the tail can be lifted.
When you do lift the tail, be prepared to use full rudder to stop the aircraft
from weather cocking into wind.
