Separation procedures in case of controlled traffic.

The Air Traffic Controller shall issue necessary information and clearances to aircraft under his control to achieve a safe separation.

Vertical separation (flight level or altitude) has to be provided according to the direction – eastern or western.

Flights above altitude 10,000 feet have to proceed under QNE (1013.2 hPa) and 10,000 feet and lower with QNH, then a pilot has to report an ‘altitude’, or if requested an Air Traffic Controller can give to the crew QFE, and then the pilot will report also ‘altitude’ but the facilities on board will indicate him a ‘height’.

Vertical separation between aircraft flying in the opposite direction is 1000 feet, until FL 290, and above FL 290 vertical separation is 2000 feet in the opposite direction.

Above FL 290 (RVSM zone) vertical separation between aircraft flying on the opposite direction is 1000 feet until FL 410, and above FL 410 – separation is 2000 feet.

Responsibility lies on the Air Traffic Controller in case of IFR flights and on the pilot in case of VFR flights.

In case of climbing/descending of an aircraft, the Air Traffic Controller has to maintain separation between aircraft using vertical rate of climb/descent.

Horizontal (lateral) separation of 20km has to be provided when the aircraft has to cross flight level (altitude) which is occupied by the other aircraft in the opposite direction. Lateral separation of 10km has to be provided when the aircraft is crossing the flight level occupied by the aircraft flying in the same direction.

Horizontal separation has to be provided between special VFR flights, when so prescribed by the appropriate ATS authority.

No clearance shall be given to execute any manoeuvre that would reduce the spacing between two aircraft to less than the separation minimum applicable in the circumstances.

Larger separation than the specified minima should be applied whenever exceptional circumstances such as unlawful interference or navigational difficulties cal for extra precautions.
