For those only interested in Private Pilot course and you are a full-time (4 days per week, 2-4 hours each day) student with a good work ethic and good study habits, you should be able to complete the course in three months.
If you are a full-time student in the Professional Pilot Program, expect 15-24 months for program completion. It is advantageous for the student to move through the program with uninterrupted flow. To do this, the school must have the equipment and manpower to accommodate you; otherwise, flying just once or twice each week can drag training out to two years or longer. Classic training sessions are 2-hour blocks and are available 7 days per week.
