Procedure and Airspace design

The complexity of designing airspace and flight paths is increasing. Today, simply flying efficiently from an economic perspective is not enough. Other perspectives such as capacity, safety and environmental perspectives also need to be taken into consideration. A great deal of the work to create airspace and flight paths concerns cooperation across borders.

While flight procedures are required to fly to and from airports. These can be based on conventional navigation instruments such as VOR, DME and NDB, or on more advanced navigation technology based on DME-DME or GNSS (satellite navigation). The latter technology is called P-RNAV (Precision Area Navigation), or RNP (Required Navigation Performance). Procedures can also be divided in two parts. The first part relates to the actual take-off and landing phases and the second part concerns the flight paths in the terminal area (TMA) to get to and from the higher-lying “air corridors”. These flight paths are called SID/STAR.

Environmental assessment increasing in importance

Today more and more of the work relating to developing airspace and flight paths is based on set environmental objectives. Environmental objectives drive development and permeate the entire enterprise. A carefully implemented environmental analysis forms the basis for decisions to reach established objectives quickly and effectively.

We can assist in the airports’ environmental assessment work, where our expertise is a crucial factor when airspace and flight paths are designed to minimise negative environmental impact in terms of both noise and emissions. Here it is important that we become involved in the work at an early stage to determine which flight path options are to be developed.

At LFV, we have unique expertise in the design of airspace and flight paths for arrival and departure and SID/STAR, based on conventional navigation technology as well as P-RNAV/RNP. Our work includes the update of existing procedures, recalculation/redesign due to the addition of flight obstacles, extension of runways and more, new design in connection with the introduction of new navigational instruments.
