Brussels Airport builds engine run-up enclosure

Foundation work has started for a new ground run-up enclosure where aircraft engines can be tested at full power following maintenance. The facility will be U-shaped, with noise barriers measuring 15 m in height to protect the surrounding area from excess noise. Local residents in Steenokkerzeel, and particularly in Humelgem, are expected to experience the biggest improvement.

Following maintenance, aircraft engines must be tested at full power before the aircraft is allowed back in the air. At Brussels Airport, this happens around 150 to 200 times a year. Currently, these test runs are still carried out in an open space, but from the end of March next year they will take place in the ground run-up enclosure currently under construction. This is expected to reduce noise levels by 10 decibels, which is perceived as half as loud.

The enclosure is being built in an area on the tarmac where several outdated buildings have been demolished. It will cover a surface area of 8,000 m² — slightly larger than a football pitch — so it can accommodate larger aircraft such as the Airbus A350 or Boeing B787. 

Foundation work is in full swing. Paving works are set to follow next, with the noise barriers erected as a final step. 

This investment of over 15 million euros is just one initiative in our broader effort to create a more sustainable and quieter airport.
