Reports didn't come in till late yesterday, not sure why it took so long. Might have legitimately been severe as they sent in a replacement, aircraft (media likes to call turbulence severe or extreme even if it's just a few moderate jolts)
Somebody ought to send them the FAA definitions...
Quote:
Light Chop. Slight, rapid, and somewhat rhythmic bumpiness without appreciable changes in altitude or attitude.
Light Turbulence. Slight, erratic changes in altitude and/or attitude. Occupants may feel a slight strain against seatbelts. Unsecured objects may be displaced slightly. Food service may be conducted and little to no difficulty is encountered in walking.
Moderate Chop. Rapid bumps or jolts without appreciable changes in aircraft altitude or attitude.
Moderate Turbulence. Changes in altitude and/or attitude occur but the aircraft remains in positive control at all times. It usually causes variations in indicated airspeed. Occupants feel definite strain against seatbelts. Unsecured objects are dislodged. Food service and walking are difficult.
Severe. Large, abrupt changes in altitude and/or attitude. Usually causes large variations in indicated airspeed. Aircraft may be momentarily out of control. Occupants are forced violently against seatbelts. Unsecured objects are tossed about. Food service and walking are impossible.
Extreme. Aircraft is violently tossed about and is practically impossible to control. May cause structural damage.
In a surprise to no one, AC 75 (Toronto - Caracas, Venezuela) has been suspended indefinitely due to the unrest.

...the airline says it can no longer ensure the safety of its operation in Venezuela, which has been roiled by daily street protests over crime and a deteriorating economy for more than a month.
The airline's last flight left Caracas on Sunday. It is offering refunds to those who have purchased tickets for flights after that.
I'm fascinated that those winglets make such a difference in Fuel Economy. I wonder how long the retrofit takes?
That bird had been in Singapore since mid-January, though it was also getting other work done. I suspect 767 retro takes time because the wing might need strengthening.

... and Venezuela is not happy about it.

Venezuela's government said on Tuesday it was breaking commercial ties with Air Canada a day after the airline suspended flights to Caracas citing the country's civil unrest.
I notice Air North is operating what appear to be 737-200 into Calgary.
1. How is this fuel-chugging, smoke generator economically viable to operate. My guess is some of the contracts that they're on, as well as some of their combi-configurations are the reason they still operate with reasonable margins
2. How is it a good idea to operate such an old aircraft over some of the most desolate terrain in North America? Not sure what the implication of this question is, but they are of course still maintained to the highest standards and are completely safe to fly. Even if the maintenance is significantly more expensive than the planes younger cousins. Also, I'm guessing their 737-200's are equipped with those awesome gravel kits, the versatility of which is probably necessary with some of their northern flying
3. It is noisy as sin, does YYC have no set cap for commercial operations to meet noise abatement requirements? Can't speak to this but as with any large airport, Calgary has NAP's in place.
Here's my stab at answering your questions. Pilots please feel free to come in and correct.

Probably all of the below
Prices in the North are high
Is payed for so only costs are operational
Likely has a gravel landing kit.
Is a combi for cargo so only 70 or so passengers
Alot of Itaki and other diamond mine charters
Noise abatement? Westjet still used that model within at least the last 10 years so unless theyve lowered it since i doubt it. Also not near alot of residential so shouldnt be much of a problem.

I flew a Canadian North 737-200 Combi up to Inuvik, NWT last year. They even had a bit from their president about having to operate such old planes in the in-flight magazine. They'd love to update to newer planes, they had some info-graphics about how much extra they waste on fuelling and maintaining these old planes. From what I remember though newer ones can't be equipped to land on some of the remote gravel airstrips they need to operate from, and the Combi really suites the needs of both passenger and cargo transport, especially when the highways up there are closed and air travel is the only option.

No new airplanes can quite meet the the capability so they've stuck with it, though once the frames hit 75,000 cycles they're done... no exceptions.
Calgary's noise procedure does nothing to quiet down the -200... no jet turns below 6,500 feet ASL, and FAA stage 2 noise planes are supposed to go off 35L (wind permitting) though I assume all operating into YYC have hushkits. I dunno how closely they adhere to this anyway. Whoopee.
