The Saint-Hyacinthe Aerodrome is an example of general aviation diversity driven by private management.

Almost all airplanes on floats land on its man-made water basin, parallel to the runway.

Single and twin engine conventional aircraft, ultralight two and three axis, aerobatic airplanes, vintage aircraft and motor gliders fly regularly from the narrow (75 ft (23 m) runway.

Aviation enthusiasts can admire aerobatics performed in the aerobatic box at the west of the airport, formation flights, low passes, and overshoot training.

Strong winds are typical of this area, much stronger than nearby airports, sometime in excess of 40 km/h (22 kn; 25 mph).
