If the landing distance available is 3000m and the runway will likely be wet, what is the maximum landing mass requirement for a turbojet aeroplane on a commercial flight?

In this scenario, the requirement for maximum landing mass is determined by the wet runway condition, which affects the landing distance due to reduced friction and braking efficiency. Certified landing performance data must be consulted to ensure safety margins are met.

For a turbojet aeroplane landing on a wet runway, it is necessary to consider the additional stopping distance usually required. This could involve adjustments for various factors, including aircraft characteristics, environmental influences, and operational regulations.

The correct answer indicates that the maximum landing mass requirement corresponds to the landing distance available under the specified conditions. When calculating the maximum landing mass, the wet runway factor is taken into account, and it's likely that the figure of 1565 meters represents a safe landing distance that the aeroplane can achieve under these conditions. This aligns with regulatory guidance for landing performance on a wet surface, ensuring that the aircraft can stop safely within the available distance, thereby making it the most suitable choice.

The other options likely reflect distances that do not meet safety requirements or operational criteria for landing on a wet runway, highlighting the critical importance of accurately assessing landing performance data based on runway conditions.
