In response to residents’ concerns, the Mimico Residents Association recently sent several questions to Porter Airlines regarding Porter’s plans for expansion and how they might impact our area. Below are responses received from Porter. We invite residents to provide comments in the box below or via email to firstname.lastname@example.org, so we can gauge community’s concerns on this matter.
MRA: Will the new planes produce more noise than the current prop planes that Porter flies?
- The CS100 will be comparably quiet to the existing Q400
- Bombardier projects that the average sound profile for the CS100 will be 85.7 decibels versus 85 decibels for the Q400. This is based on standard industry measures of approach, take off and fly by. A person could not tell the difference between these two sound levels simply by listening
- Porter also has guaranteed aircraft performance and sound measures built into its conditional purchase agreement with Bombardier. If the CS100 does not meet these standards, the contract can be cancelled
MRA: What is the flight path of the planes and will they/do they pass over Mimico (including when there is bad weather – RFI?)?
- Existing approach flight paths approved by NavCanada operate over water approximately 98.5% of the time
- In low visibility conditions, the approved approach flight path from the west briefly takes aircraft over south Etobicoke at 2,000-feet elevation. This amounts to approximately 400 flights per year, or just over one per day on average
- The CS100 is capable of operating using the same Q400 flight paths
- Porter has invested significant resources and worked with NavCanada in the last seven years to further improve flight paths at the airport using the latest technology
- We anticipate further improvements before the CS100’s proposed entry into service at Billy Bishop Toronto City Airport in 2016 that eliminates all flying over the mainland in all conditions for all commercial flights
MRA: What is the expected increase in the number of planes taking off and landing (% increase and/or flights per day)?
- The CS100 will fly longer routes, meaning it will be away from the airport for as much as 10-12 hours. This means the frequency of take offs and landings per aircraft is much less
- An estimate of 22 additional roundtrips per day is possible
- This remains contingent on available airport slots, plus the airport’s existing NEF 25 noise contour that limits total airport noise. This measure will not change under Porter’s proposal and is one of the key factors ensuring that the airport will never grow to the scale of major international airports
