Sec. 25.523 - Design weights and center of gravity
(a) Design weights. The water
load requirements must be met at each operating weight up to the design
landing weight except that, for the takeoff condition prescribed in
§25.531, the design water takeoff weight (the maximum weight for water
taxi and takeoff run) must be used.
(b) Center of gravity positions.
The critical centers of gravity within the limits for which certification
is requested must be considered to reach maximum design loads for each
part of the seaplane structure.
