Canada's Minister of Transport Marc Garneau reportedly requested Air Canada to retrofit up to 100 A320s in an effort to remove a high-pitched whistling noise allegedly made by the aircraft when landing at airports in Toronto, Montreal and Vancouver (Globe and Mail, 28-Dec-2017). Mr Garneau said: "This retrofit would lead to a tangible impact on noise, with potential reductions of five to 11 decibels for A320 aircraft". Air Canada stated it will review the government's recommendations.
