Canadian Idol Puts Spotlight on Yellowknife

Canadian North was very excited at being the northern airline of choice for Canadian Idol. Mr. Ben Mulroney, host of Canadian Idol, and the rest of the hard working crew arrived in Yellowknife on February 21st for a frantic, action packed, whirlwind trip. In addition to doing the auditions, the Canadian Idol crew managed to enjoy some distinctly northern experiences, including dogsledding, snowshoeing, northern lights viewing and some good ol’ Yellowknife hospitality.

Canadian Idol’s trip to Yellowknife produced six contestants for the Vancouver auditions. With a total of 107 singers, Canadian Idol judges were pleasantly surprised to be handing out so many of the sought-after blue tickets. Six young singers advanced to Tier II and flew compliments of Canadian North to Vancouver to go before celebrity judges on February 27th.

Canadian North is the preferred carrier for northern business travelers. With our convenient flights to trade shows and conventions, you can focus on growing your business and connecting with your next business lead. Make sure you ask for our convention rates when you book your next flight and our special cargo rates to transport your displays and materials. Watch for additional flights scheduled to accommodate upcoming trade shows and conventions. Aside from the judges and winning contestants in Vancouver, the public will not be told who advances to the finals in Toronto. Contestants who get a blue ticket in Vancouver must keep it a secret ... if they tell, they risk being disqualified from the next competition. The stakes are high so it will be a secret well-worth keeping!

As for the rest of us, we will have to wait until CTV returns in June with the fourth season of Canadian Idol. To give you an idea of Canadian Idol’s popularity, at the end of last year’s third season, viewers had cast an astonishing 38 million votes. Last year’s series alone was watched by over 17 million viewers, representing almost 60 percent of Canada’s population.

Stayed-tuned for CTV coverage on the Yellowknife Canadian Idol – you may recognize some local sights and see some familiar Canadian North faces!

Pressurization – Sitting pretty at 11,300 m (37,000 ft)

By Laval St. Germain, Chief Pilot Canadian North

How is it that I can sit in an airplane at cruise altitude and have no problems breathing?

Large pressurized jet aircraft are capable of operating at very high altitude to take advantage of the lower fuel burns available at these altitudes. If you were standing on a mountain that was 37,000 feet above sea level, you would only last seconds before succumbing to the effects of altitude and cold temperatures.

So, how do we make it possible to sit comfortably in your seat reading this magazine at 37,000 feet?

Pressurization. Jet engines suck in huge quantities of air, then compress this air and accelerate it through the various compressor blades in the engine. Some of this air passes through the hot section of the engine where fuel is added and it is ignited to further accelerate this now very hot air. This high velocity hot air passes over turbine blades and out the back of the engine which pushes the aircraft through the sky. Not all of the air passes through the hot section of the engine, we use some of this air to pressurize the cabin of the aircraft. To put it simply we “inflate” the cabin that you are sitting in just like an aluminum balloon, using the high pressure air from the engines’ compressors. The question usually arises; but are we adding oxygen
to the cabin? No, here’s a quick lesson on the atmosphere and human physiology:

The common misconception is that the reason we cannot breathe at high altitude is because there is less oxygen. The truth is that the percentage of O2 (oxygen) in our atmosphere remains constant at about 21% regardless of altitude. The atmospheric pressure however, decreases considerably from sea level as you climb. This drop in atmospheric pressure results in a drop in partial pressure. This drop in pressure, to put it very simply, prevents O2 from being “pushed” into the lungs alveoli which directly allows transfer of O2 to the bloodstream.

What the pressurization system in the aircraft does, is “pushes” high pressure air into the cabin after it is cooled and filtered through a cooling turbine and heat exchanger. This air increases the cabin’s atmospheric pressure which allows the transfer of O2 into the bloodstream, that’s why you can comfortably sit reading this magazine and the only thing taking your breath away is the stunning scenery of Canada’s north out your window.
