Advanced navigation capabilities permit aircraft to follow more predictable, efficient flight paths, and access a wider range of departure routes. This candidate solution introduces advanced curved departure routes using more flexible standard instrument departure (SID) designs with the aim of  fostering improvements in airport-airspace efficiency, flight efficiency and lowering the air traffic environmental impact (gaseous emissions and noise) by providing the means to avoid environmental constraints in the terminal area. This is achieved through the use of more dynamic departure routes compared with today’s operation.

SESAR partners are developing new SIDs designed for advanced GNSS-based procedures in the terminal area that enable airlines to fly more efficient departure routes based on curved operations rather than today’s point to point routes.

The use of GNSS (such as Galileo) enable aircraft to fly RNP trajectories with high accuracies e.g. 0.3 nm. Advanced GNSS based SIDs can enhance the variety, flexibility and repeatability of departing aircraft, e.g. with an early immediate turn after departure which can allow an aircraft to depart in the desired direction. This capability can allow a more flexible SID design in single and parallel runway operations and lead to environmental improvements.

By initiating advanced curved operation after departure, new SIDs will enable more efficient terminal operations, improve runway throughput, and lower environmental impact.
