What is the maximum distance between points when applying nonradar separation?

The maximum distance between points when applying nonradar separation is set at 500 miles. This standard is based on regulatory guidance and operational practices that ensure adequate spacing between aircraft to maintain safety in the airspace system. Nonradar separation refers to the methods used to maintain safe distances between aircraft without the use of radar, relying instead on other forms of communication and navigation aids.

In applying nonradar separation, the established maximum distance helps to ensure that pilots and air traffic controllers have enough time and information to react to any potential air traffic conflicts, thereby maintaining safe operations. Given that the nonradar separation distance is guided by regulatory practices, it is essential for all personnel to be aware of these limits to uphold aviation safety.
