Contexto
The required separation between aircraft is generally expressed in terms of minimum distances in each dimension which should not be simultaneously infringed. In the case of horizontal separation, the minimum distance can be expressed in either nautical miles (NM), degrees of angular displacement or, in the longitudinal dimension, as values of either time-based or distance-based minima, by use of distance measuring equipment (DME), area navigation (RNAV), radar or automatic dependent surveillance (ADS) respectively (Doc 4444, Procedures for Air Navigation Services — Air Traffic Management, PANSATM). Vertically, the minimum is expressed in either metres, feet or flight levels.
