Subject Title

Subject Description
This subject provides a detailed study of the theory of aviation meteorology as well as Environment Canada and Nav Canada weather services provided to aircrews for flight planning in commercial flight operations. Topics covered in weather theory include the properties of the atmosphere, humidity, clouds, atmospheric heating, cooling and stability, pressure, altimeter errors, air circulation below and above the boundary layer, jet streams, air masses, frontal structure and associated weather, visibility and transitions, thunderstorms, icing, turbulence and low level windshear. Topics covered in weather services include area, aerodrome and upper wind forecasts, weather reports, signets, radar reports and weather charts. Topics covered in flight planning include the analysis and application of meteorological data in daily flight operations. A passing grade must be obtained in this subject in order to be recommended to attempt the Transport Canada written Private and Commercial examinations.

Credit Status
One credit toward the Commercial Pilot Training Certificate

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Obtain, analyze and apply all of the weather information services provided for commercial flying, VFR & IFR, then make the required, safe, appropriate decisions for a pre-flight plan.

2. Competently follow and analyze weather systems as they develop in flight, applying weather theory in order to determine the criteria for safe aircraft operation to destination or alternate aerodromes in any weather situation.

Cheating and Plagiarism
Each student should be aware of the College's policy regarding Cheating and Plagiarism. Seneca's Academic Policy will be strictly enforced.

To support academic honesty at Seneca College, all work submitted by students may be reviewed for authenticity and originality, utilizing software tools and third party services.

Mode of Instruction
Theoretical study (lectures, discussions)  and practical  application.  All classes start with a review of previous work, including a two-way question period to ensure student progress.  Several ‘programmed instructional packages’ are included, which allow students to review selected work at their own pace.

Modes of Evaluation
Since this is a professional credit subject, marking standards reinforce professional practice by demanding legible, tidy work. Assignments should be well organized and grammatically correct, with proper spelling and punctuation. Late assignments are penalized. For particulars, please obtain standards, dated, etc. from your instructor. 

While attendance and participation in class discussions are not formally part of this evaluation schedule, you should be aware that absenteeism will almost guarantee your inability to achieve satisfactory grades. Some of the progress tests and quizzes may not be announced in advance and details of assignment requirements may be explained in class. There is no formal provision for make-up tests to replace tests you miss. 

To attain a passing grade for the subject, a student must complete and obtain a passing grade on all combined assignments and tests. For further information on evaluation and academic standing, see a copy of Academic Policy. 

Grading is based on the following marking scheme:

Termwork 25%
Midterm Exam 25%
Final Examination 50%
Total 100%

All tests and final examinations are closed book. 
Because of the special nature of the classroom discussions, attendance is essential in each class. Each student must complete all forms of evaluation in order to pass the subject.
