The correct answer is: C. More than the maximum structural landing weight.
The maximum gross takeoff weight of an aircraft is the maximum weight at which the aircraft is allowed to take off. It is determined by the aircraft’s structural strength and the available runway length. The maximum structural landing weight is the maximum weight at which the aircraft is allowed to land. It is determined by the aircraft’s structural strength and the available runway length.
The maximum gross takeoff weight is always greater than the maximum structural landing weight because the aircraft must be able to accelerate to take-off speed and climb to altitude with the additional weight of the fuel and passengers. The maximum structural landing weight is less than the maximum gross takeoff weight because the aircraft must be able to decelerate to landing speed and land safely with the additional weight of the fuel and passengers.
Option A is incorrect because the maximum gross takeoff weight is always greater than the maximum structural landing weight.
Option B is incorrect because the maximum gross takeoff weight is always greater than the maximum structural landing weight.
Option D is incorrect because the empty operating weight plus the payload is not necessarily equal to the maximum gross takeoff weight.
