Q400 and Toronto City Centre

[Big Pratt]

The yuppy, NIMBY condo owners along the shore find all airplanes so repulsive, that the mighty Q400 actually lifts off well before the usual Vr.

This repulsive force is so strong in fact, that Bombardier needed to issue an appendix to the performance manual, applicable only to CYTZ.

Great little airline this Porter is!

They are very, very clever. If you promise not to tell CommunityAir,the secret is this...they don't take off at maximum gross weight.

Smart huh?

Full load of pax, what is the v1 and vr and rough t/o distance ?

Wouldn't they vary siginfigantly with baggage load and fuel uplift?? They fly relatively short legs and I bet the baggage hold is not often completely full.

Full load of pax, what is the v1 and vr and rough t/o distance ?

With full pax load and plenty of extra fuel for the routes Porter flies, the Q400 has to be able to accelerate to V1, have an engine failure, and then come to a complete stop before the end of the runway (without using reverse) - which is the limiting factor in calculating takeoff length (and also what the 4700ft number at MTOW refers to). In the summer time, performance is degraded because of heat and the Q400 still has no problems out of YTZ with full seats.

The key, as was mentioned already, is that Porter does not have to also fill the tanks full to satisfy fuel requirements on the short routes that Porter flies. The Q400 is capable of going much further than what will ever be offered out of the island airport.

Incidently, the Q400's actual takeoff roll is probably somewhere close to 3000ft on a hot, heavy, calm wind takeoff at YTZ.

Porter flies the intermediate gross weight version of the airplane...and doesn't fly long distances, thus doesn't carry lots of gas.
Our passengers also tend to travel light as do most regional airline pax.
I have yet to bump pax or bags with a full load out of the island... and more often than not we are still able to use a reduced power takeoff and
achieve all takeoff performance criteria.

[Rockie]

I don't fly it, so:

V1 - don't know
VR - don't know
TOD - less than 4000 feet.

Speeds will vary depending on takeoff flap setting, total weight and engine power if they use derated takeoffs. The airplane generally does 2 hour legs, so they won't have anywhere near full fuel and will be well below MTOW when departing from TCCA. I don't know details, but rest assured that they meet all the performance certification requirements or they wouldn't be operating.

Here is the link I read that prompted this thread .......

uhhhh... don't listen to those guys. They're a little bit upset and will say anything to Porter out of their backyard!

[Rockie]

CommunityAir never let facts get in the way of their agenda. When the real facts don't support their case (which they never do) they make them up, and nothing is too preposterous for them. In Miller's first election they were handing out tripe showing 747's flying around the CN Tower. There is no one there who has an inkling of understanding of all the statistical garbage they quote.

They just hate airplanes.

[EI-EIO]

it's almost sad that Porter are doing so well - when I flew with them YTZ-YOW there was 8 seats full out of 70 - the takeoff was brisk to put it mildly. Doubt the load would be as light these days what with the Premier and other nobs flying Porter.

The jetway at the Ottawa end was a pleasant surprise too

Thanks for the good laugh that web site is funny. Up until those boneheads succeed.

One could use that fearmongering philosophy to put forward the arguement that all the roads in the Great city of Toronto should be closed .

It is a well known medical fact that criminals use the roads to travel between crimes scenes to rape ,murder and pillage .Way too hard to carry all that loot on the TTC
So if they closed all the roads in Toronto no crime .Overnight cure
If you already live in the center of the universe you do not need personal transport .ie no car too many cars on the planet anyway ,Canada is all aboot Canoes anyway and you do live on the waterfront so you do not need to carry your national symbol of transport from your igloo far to the amazing super highway of water that is connects most of the world .
Canoes are peaceful.If they had more canoes in Afghanistan i bet those people would be peaceful just like us.
We could turn all the roads into cycle paths as not many people die on cyclepaths and when you consider how many people die every year driving on the roads ,not to mention all those walking wounded who would be better off being living donours so that someone who really kows how to party can put those kidneys and liver to use.Nobody has managed to do a brain transplant yet .Although some of the brains on the waterfront would get a fair price on the black market for organ donours as they have not seen much use
Imagine how small the carbon footprint would be if they closed all the roads in the big tzero
