Sec. 25.531 - Hull and main float takeoff
condition.
For the wing and its attachment to the
hull or main float --
(a) The aerodynamic wing lift is assumed
to be zero; and
(b) A downward inertia load,
corresponding to a load factor computed from the following formula, must
be applied:
where --
n=inertia load factor;
CTO=empirical seaplane operations
factor equal to 0.004;
VS1=seaplane stalling
speed (knots) at the design takeoff weight with the flaps extended in the
appropriate takeoff position;
β=angle of dead rise at the main step (degrees); and
W=design water takeoff weight in pounds.
