In its civil role the civilian personnel (using the military radar) controlled air traffic, primarily over the Atlantic to ensure correct height and separation.

Under such conditions, it may be impractical for standard civilian air traffic controllers to ensure safe separation of the aircraft.

It is important for the State Department to establish an independent statistical bureau to ensure separation between objective reporting and political interpretation of its statistics.

These procedures use aircraft position reports, time, altitude, distance, and speed to ensure separation.

To ensure safe separation from terrain and other obstructions, high degree of accuracy and reliability is required from a pressure sensor.

The controller "sees" the airplanes in the control area and uses VHF voice to provide instructions to the flight crews to ensure separation.

The fuze for a retarded bomb requires a minimum time over which the retarder is open to ensure safe separation.

Local planning authorities ensure clear separation between urban and recreational areas and there are many protected nature reserves.

Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches.

To ensure clean separation and prevent contact, multistage rockets may have small retrorockets on lower stages, which ignite upon stage separation.
