What is the distance within which an aircraft must be informed of closest traffic when it is in LUAW?

When an aircraft is holding in a line up and wait (LUAW) position, it is crucial for the pilot to be aware of any potential conflicts with nearby traffic. The standard procedure stipulates that if another aircraft is within a specific distance, the pilot of the LUAW aircraft must be informed about it.

In this case, the correct distance is six flying miles. This guideline helps ensure safety by allowing the pilot to be aware of aircraft that could impact their operations, enabling better situational awareness and preparation for potential takeoff or other actions. Being informed about traffic at this distance provides the necessary margin for decision-making and responding to changing conditions, thereby minimizing the risk of collisions during critical phases of flight.
