You are suggesting that we restrict our citizens freedom of movement, remove key links from smaller cities in Canada to Toronto, dictate to airlines what routes they can run , when and the equipment they should use, and all this so we can delay building a desperately needed airport for a couple of years? An airport that BTW will help Canada meet its 2030 emissions targets.
But hey, stranger things have happened, for instance , the no-jets lobby in Toronto stopped porter airlines from utilizing a quieter more fuel efficient , lower emissions per km aircraft ( the CSeries ) by convincing everyone that extending the city center runway by 1000 ft would be bad for the environment. A true “ thankyou for smoking moment” .
Q400 - on a 500km route is 3.49 liters per 100 km per seat
Even on the shortest routes , the CSeries 100 A220-100) is under 2.6 liters and rivals the A319Neo
The CSeries ( A220-100) drops to 2.28 Litres per 100 km per seat on medium routes and down to 2 on longer routes.
The q400 drops to only 2.7 under ideal long haul conditions.
Contrary to popular believe a number of larger aircraft burn more gas per seat.
For instance, the A380 under idea long haul conditions never goes below 3 liters per 100 km per seat.
You don’t have to take my word for it, you can get great Performance numbers with commercial route planning software( like piano X, the A380 is included with the free trail), but there are many other sources for this same info.
Note: Taxi time is a huge variable here, it’s 5 min at the island, 20 min and building at congested Pearson. Building Pickering today will be a huge boost to fuel efficiency of short haul routes and reduce carbon emissions across the board.
This is not even including the expected savings for more even traffic disruption and shorter drive times the urban planners are so excited by.
So have at it.
