What is the minimum distance for selecting a landing site from the nearest TDP of unlike or unknown aircraft?

The minimum distance for selecting a landing site from the nearest Touchdown Point (TDP) of unlike or unknown aircraft is 100 meters. This standard distance is established to ensure safety and minimize the risk of collision or interference with operations by different types of aircraft. The 100-meter separation allows for adequate clearance and provides a buffer zone to account for the unpredictable behavior of unknown aircraft, which could include factors such as wind conditions, wake turbulence, or unexpected movements. This distance is particularly critical in environments where various aircraft may be operating in close proximity, thereby reducing potential hazards during landing and takeoff procedures.
