As the nose-wheel
raises off of the runway, the pilot should hold
aileron pressure into the wind. This may cause
the downwind wing to rise and the downwind main
wheel to lift off the runway first, with the
remainder of the takeoff roll being made on
that one main wheel. This is acceptable and
is preferable to side-skipping.
If a significant crosswind exists, the pilot
should hold the main wheels on the ground slightly
longer than in a normal takeoff so that a smooth
but very definite lift-off can be made. This
allows the airplane to leave the ground under
more positive control and helps it remain airborne
while the pilot establishes the proper amount
of wind correction. More importantly, this procedure
avoids imposing excessive side-loads on the
landing gear and prevents possible damage that
would result from the airplane settling back
to the runway while drifting.
As both main wheels leave the runway, the airplane
begins to drift sideways with the wind as ground
friction is no longer a factor in preventing
lateral movement. To minimize this lateral movement
and to keep the upwind wing from rising, the
pilot must establish and maintain the proper
amount of crosswind correction prior to lift-off
by applying aileron pressure into the wind.
The pilot must also apply rudder pressure, as
needed, to prevent weathervaning.
