Mont Yamaska Airspace

Airspace classes you need to know

As a pilot, it is essential to be familiar with the airspace around Mont Yamaska—both for takeoffs and landings and for cross-country flights.

Three classes are relevant in the region:

  • Class G: Uncontrolled. Free flight is permitted.

  • Class E: Controlled. Free flight is permitted under certain conditions.

  • Class F: Special use. It may be controlled or uncontrolled and often serves as advisory airspace to inform other pilots of our presence.

Important: Mont Yamaska is located primarily in Class F, which becomes Class G when activated—allowing free flight without restriction.

Free flight in Class E: mandatory conditions

Free flight in Class E airspace (above 700 feet AGL) is permitted if you meet all of the following conditions:

  • Be 16 years of age or older

  • Hold a medical certificate (category 1, 3, or 4)

  • Have passed the HAGAR exam (score of 60% or higher)

  • Be on a cross-country flight

  • Be equipped with an altimeter and a compass

  • Notify the Flight Service Station (FSS) of departure time and estimated flight duration
