Discovering the GRE

With its aerodynamic design and innovative sound absorbing panels, the Airport Authority’s Ground Run-Up Enclosure (GRE) showcases the latest in noise-reducing technology and is a key component of the Airport Authority’s Noise Management Plan

And it’s these innovations that prompted The Discovery Channel’s popular science program The Daily Planet to take a behind-the-scenes look at the facility.

In the segment Embedded With Mark Miller, host Mark Miller toured the GRE with members of YVR’s Environment Team to get an in-depth look at how the GRE uses the latest technology to reduce aircraft run-up noise in our community. As well as a tour of the massive 67- by 80-metre facility, Miller also accompanied Pacific Coastal Airline's Saab 340 as it taxied into the GRE to performed a routine engine run-up.

To further show how the GRE's 1,000+ sound absorbing panels, louvered vents and aerodynamic design work together to reduce noise, Miller used a decibel metre and took readings inside and outside of the facility. Not surprisingly, the readings showed a marked difference between the two.

Engine run-ups are required as part of stringent safety standards whereby operators test engines and their components before an aircraft is put back into service after maintenance. The GRE works by re-directing engine run-up noise up instead of out, and is the first its kind at a Canadian airport.

If you missed the segment when it aired on TV, you can watch the episode on The Discovery Channel online. Want to see the GRE in person? Visit our new outdoor viewing platform located in the parking lot at the South Terminal.
