AC A320's cause of GTAA noise complaints - complaints, and retrofit
Interesting report came out today:
"Of relevance to Toronto arrivals, is the known noise issue associated with the Airbus A320 family of single aisle aircraft. This is often described as a high-pitched whine, and is generated by the Fuel Over Pressure Protector (FOPP) cavities under the wings. The whine is audible under the approach of these aircraft, normally between 7NM and 15NM from touchdown. About 18% of all arrivals at Toronto are A320 family aircraft.
Air Canada is the largest operator of Airbus A320 series aircraft at Toronto, and at the time of writing, has 73 such aircraft in its active eet.
Airbus, the aircraft manufacturer, has developed a modi cation to address this noise phenomenon, and report that it will deliver an improvement of up to 9dB; this is almost a halving of the volume perceived by the human ear."
and the need for an effort to try to get AC to do a retrofit:
"Recommendation 1A: NAV CANADA should formally write to Transport Canada requesting them to consider establishment of a sunset date of December 31st 2020 for the operation, in Canada, of
Airbus A320 series aircraft without the Fuel Over Pressure Protector cavity vortex generator noise modi cation.
Recommendation 1B: As an indication of GTAA’s and NAV CANADA’s commitment to noise reduction, and a tangible indication to local communities that the noise impact of the airport is taken seriously and; to incentivise an accelerated noise modi cation by all airlines using A320 family aircraft at Toronto; NAV CANADA should formally approach the GTAA about the establishment of an earlier sunset date
for unmodi ed Airbus A320 family aircraft using the airport, such as two years after publication of this report. With an appropriate noise penalty applied for non-compliant aircraft immediately thereafter, if lawful within the GTAA’s or NAV CANADA’s charging regimes."

Why would AC not step up to the plate on this? Anyone with a sense of the $$$ involved?

What stepping up to the plate dopes AC have to do? There is no regulatory requirement for this to be done, so why would AC waste time and money doing something there is no regulatory requirement to do? The fix will not increase revenue either, and with many A320 series leaving the fleet over the coming years, there's even less reason to spend the money on something that does nothing to improve the bottom line.
More deets regarding the A320 whine can be found on the a320 whine website.

Noise around YYZ
The Greater Toronto Airports Authority has commissioned a study to consider ways of reducing noise around YYZ. Per this article, the group who did the study "examined airports in 26 cities around the world with similarities to Toronto, including Los Angeles, Frankfurt, Sydney and Dubai."
One of the findings was that European airports add a fee to the take off / landing fees if noise is excessive. This supposedly incentivizes the airlines to use quieter aircraft. Specifically,
So which airline uses the A320 out of GTAA? And do we think an extra fee will incentivize them to speed up the 737-Max replacement program or will the fees simply become another source of revenue?

The report also recommends that the GTAA specifically target the notoriously noisy Airbus A320, which can be retrofitted for quieter operation. Those planes make up 20 per cent of Pearson traffic, according to the GTAA.

clearly a commitment from AC to be "fixed" or sold is needed by late 2019.
after than charge any 320 operator huge money to land the flying junk.
Oh a side note perhaps thats why AC is crashing these planes, cheap way to fix the problem.

The 737 delivery schedule is pretty much locked in at this point, so a fee for noisy 320s would have to be extremely high to get AC to speed up 737 deliveries.
