Selected Modes of Operation for Suvarnabhumi International airport.

Segregated Parallel Approaches/Departures (Model:4) will be the standard operating mode for Suvarnabhumi International airport. There may be semi-mixed operations, i.e. one runway is used exclusively for departures, while the other runway is used for a mixture of approaches and departures; or, one runway is used exclusively for approaches while the other is used for a mixture of approaches and departures, there may also be mixed operations, i.e. simultaneous parallel approaches with departures interspersed on both runways (ICAO DOC9643). Several types of parallel runway operations, which are described as operational models maybe conducted in segregated parallel approaches an departures.

The utilization of operational models shall be based on traffic situations at the time with the purpose to achieve an orderly and expeditious flow of traffic. The criteria shall also meet the most effectiveness of runway utilization. However, as far as the operational model is selected, the basic concept of operating aircraft on ground movement area shall not aim at the shortest taxi route to the active runway but the respective departure direction. In addition, the selected model should support the independent parallel departure operation with safety and maximum runway capacity.

  Operational models

The operational models applicable to Suvarnabhumi are described, together with related RNAV SIDs as follows.

  For air traffic management and effective traffic flow, runway 19L and 01L shall be mainly used for departure while runway 19R and 01R shall be used for arrival.

  The use of runway different from mentioned may be possible as considered necessary under special circumstances, such as adverse weather conditions or operational necessity. In normal situation and only when traffic permits, ATC may initiate pilots to depart and land on the appropriate runway.
