longitudinal separation

[‚län·jə′tüd·ən·əl ‚sep·ə′rā·shən] (navigation) In air-traffic control, the separation of aircraft along a longitudinal line.

longitudinal separation

Relationship between location of center of gravity and stability of an airfoil/control surface.The longitudinal spacing of aircraft at the same altitude with the minimum distance expressed in units of time. Longitudinal separation is achieved by requiring aircraft to depart at a specified time, to lose time to arrive over a geographic location at a specified time, or to hold over a geographical location until a specified time. Longitudinal separation between supersonic aircraft during the transonic acceleration and supersonic phase of flight is achieved by timing the start of the transonic acceleration appropriately rather than by imposing speed restrictions during supersonic flight.
