Longitudinal separation

Longitudinal Separation
Longitudinal separation is the separation of aircraft following the same course at the same altitude. In simpler terms, it is the separation required between two aircraft flying one in front of the other.

Longitudinal Separation: The longitudinal spacing of aircraft at the same altitude by a minimum distance expressed in units of time or miles.

Longitudinal separation is normally 3-miles in trail. The aircraft in front cannot be heavier than the plane behind and the tower must be able to see the runway's turnoffs.

Preventing collisions is referred to as separation, which is a term used to prevent aircraft from coming too close to each other by use of lateral, vertical and longitudinal separation minima; ...
