The correct answer is D. All of the above.
The minimum turning radius of an aircraft is the smallest radius around which it can turn without losing control. This radius is determined by the aircraft’s design and weight, and it is important to consider when designing and building an airport. The minimum turning radius of an aircraft will affect the size of the apron, which is the area where aircraft are parked and refueled, and the radius of the curves at taxi-ends, which are the areas where aircraft turn from the taxiway onto the runway.
The take-off and landing distances for an aircraft are the minimum distances that the aircraft needs to travel in order to take off and land safely. These distances are determined by the aircraft’s weight, engine power, and the runway conditions. The take-off and landing distances for an aircraft will affect the length of the runway that is needed at an airport.
The length of the normal haul of an aircraft is the maximum distance that the aircraft can fly without refueling. This distance is determined by the aircraft’s fuel capacity and its fuel efficiency. The length of the normal haul of an aircraft will affect the frequency of operation of an airport, as aircraft will need to refuel more often if they are flying longer distances.
Therefore, all of the statements in the question are correct.
