use
a,n
obstacle
liftoff speed,
and allowanoe
should
be
made for

If liftoff

or
glassy

the
following
procedure
is recommended:

float out
of the
water' When
one float
leaves the water, appty sligbt elevator

Care
must be taken to stop the

rudders retracted
when the floatplane is on the step;
the

of the
takeoff is normal.
If
the floats are lifted
from the
