Reducing the noise of arrival aircraft

Coming up in March 2022, a second series of trials of a new SESAR solution which can reduce the noise of incoming aircraft. French and Italian SESAR JU members have been conducting live trials of ‘increased second glide slope’ (ISGS) solution, which significantly reduces noise for the communities surrounding the airport by changing the angle of the aircraft as they make their final descent. This is all made possible thanks to the level of precision offered by enhanced satellite-based navigation systems which are opening up possibilities when it comes to designing more eco-friendly and optimised arrival procedures at airports.

A first, successful series of trials has already taken place at Rome’s Ciampino airport, a regional airport which accommodates commercial, military and general aviation traffic. 30 flight approaches were conducted by ENAV and Dassault Aviation, partners in the SESAR JU project DREAMS. The second trial series will be performed by SESAR 3 JU member Honeywell, to explore additional aspects related to the different conditions in carrying out ISGS.
