Frequently asked questions
Is customs available at CYSC?
Yes, Sherbrooke Airport is designated as an Airport of Entry, meaning customs clearance is available on site. Crews arriving from the United States can process entry formalities directly at CYSC without diverting to another port. This AOE status makes the field a practical option for cross-border business aviation flights into the Eastern Townships region of Quebec. Dispatchers should still confirm current hours and any advance notice requirements with the customs office before planning an arrival.
What runway length is available at Sherbrooke Airport?
Sherbrooke Airport, CYSC, offers two paved runways of equal length. Runway 13/31 and runway 14/32 each measure 6,000 feet long and 150 feet wide, both surfaced in asphalt. This gives operators two runway orientations to work with depending on wind conditions, without a difference in available landing distance between them. The matching dimensions simplify performance planning since crews do not need to compare shorter and longer options.
How much business aviation traffic does CYSC handle?
Sherbrooke Airport recorded 603 business aviation operations against a total of 949 cross-border operations tracked by FAA TFMSC in 2025. This traffic reflects cross-border movements as seen by the FAA rather than the airport's full operational count. Business aviation makes up the majority share of this recorded activity. The figures give dispatchers a sense of relative traffic density at CYSC compared to larger regional fields, though they should not be read as a complete picture of all local flying.
Is business aviation traffic at Sherbrooke Airport spread evenly through the year?
No, traffic at Sherbrooke Airport is concentrated in specific months rather than spread evenly. August recorded 101 business aviation operations and September recorded 90, both well above the monthly average seen across the rest of the year. By contrast, January and December each saw fewer than 30 operations. Dispatchers planning flights into CYSC during late summer should expect higher activity levels than during winter months.
What are winter conditions like at CYSC?
Winter temperatures at Sherbrooke Airport are consistently cold, with average high temperatures around 23 to 26 degrees Fahrenheit in January and February according to source climate data. Days with temperatures below freezing are frequent, averaging above 27 days per month across December through February. Snow accumulation of one inch or more was recorded on an estimated 2.8 days in March, an estimate attributed to the source climate agency. Crews should plan for cold-weather operational procedures and runway surface conditions typical of a Quebec winter at this field.
