I'm sorry, Navigator
, but I feel I must jump in here with some questions, based on your post here:
I have completed a canadian commercial pilots course and This is my area where I did my training I know the vector airways here.On a hot
summer day in the middle of a big high presure system the atmoshere is pretty calm and no where near cold enough to create a vapor
The "canadian commercial pilots course" you refer to...was it merely the test-prep, textbook-type study? OR, have you actually gotten your Canadian
pilot's licence? If not yet licenced, how much practical experience do you have under your belt?
As you are no doubt (?) aware, it is similar to the US system, under jurisdiction of the FAA, in terms of Airman Certificate licen(s)ing ('license'
is the American spelling). One progresses gradually, starting from Student, to Private and eventually, after accumulating sufficient experience, and
additional training, can go on to get qualified with a Commercial Licence (or higher).
, of course, along the way is a lot of what we term "Ground School". Simply, the study undertaken on the ground, either in a
structured course administered by accredited institutions, or on one's own. ALL to ultimately be able to pass the various written exams one must
hurdle, on his/her journey to becoming an ever more experienced pilot, and earning more advanced Certificates and Ratings.
NOW...I am puzzled by your assertions, and terminology (although it could be a simple typo):
I did my training I know the vector airways here.
Ummmm...we refer to those as "Victor" Airways. Down here in the States, and yes, even up in the 'frigid' North.
BUT (and I'm surprised you didn't realize this) 'Victor' Airways are only associated with 'low altitude' routes (in North America). Victor
Airways are not valid ABOVE FL 180.
(That's an important concept to remember, hope you might be catching on by now...)
On a hot summer day in the middle of a big high presure system the atmoshere is pretty calm and no where near cold enough to create a vapor
NOW, you are simply repeating the same mistake that laypeople
make!! It sounds as if you're equating the temperature conditions on the
ground (under the 'high pressure system') and saying that because it's a "hot summer day" where you are, that it must also
hot at altitude for contrails to form?!?
Is this the gist of your assertion? Because, if it is...I can tell you you are in error.
You've 'completed' the commercial study, right? Go back and study the section, again, on meteorology. I would expect (well, I know) that every
pilot's licensing study course has that section.
I suggest a review on the topic. Pay particular attention to the adiabatic lapse rate information, for starters.
Back to 'Victor' Airways (low altitude) versus 'Jet' Airways (high altitude...above FL 180).
It is entirely correct that airplanes at or below 18,000 feet are very unlikely to form contrails...the air just isn't conducive to that, at those
To learn more about the structure of Airways, both US and Canada (although I don't know where in Canada you are, I'll just randomly pick) a person
can either go to an airport and BUY the associated navigational charts, OR...you can view them for free here:
Actually, that source is for US charts....but, for say...Quebec, you can type in the ICAO airport code (CYQB) and the chart will center there, but it
will mostly show hte US airspace south, not the Canadian airspce farther north.
You probably know what a "Sectional" and "WAC" chart are...the buttons labeled "Enroute L-x" or "Enroute H-x" (where "x" is a number of the
chart) will display the IFR charts, both 'Low' and 'High', as selected.
Those charts all have panels at the ends with a key to deciphering most of the symbols and terminology, too.
Enjoy the free lessons!!!
Breaking news!!! For our 'hoser' cousins Up North!!
