释义 |
common point common pointA significant point over which two or more aircraft will pass, or have passed, before proceeding on the same track, or diverging tracks. Such a point can be a single fix, whether a NAVAID (navigational aid), a fix derived from NAVAIDs, or geographical coordinates expressed in degrees of latitude and longitude. A controller must establish a common point not originally in the flight plan and then clear the aircraft to fly over the point so that adequate longitudinal separation can be maintained. |
