A320 Family Retrofit Program
The Airbus A320 family aircraft produce a high-pitch whining sound on approach caused by small vents on the aircraft’s wings designed to help equalize and mitigate over-pressurization (Fuel tank Over Pressure equalization Ports – FOPP). The A320 family includes the A318, A319, A320 and A321 aircraft. Retrofit kits can be installed to eliminate the high-pitch sound and reduce noise by up to 9dB, resulting in a significant noise reduction for communities.
Toronto Pearson monitors the usage of the A320 family operations based on retrofit status information provided by airlines.
