Frequently asked questions
How long is the runway at CYMT?
Chapais Airport (CYMT) has a single paved runway, designated 04/22, measuring 6,496 feet long and 150 feet wide. The surface is asphalt, and the length matches the airport's published maximum paved distance, meaning this runway represents the field's full paved capability. There is no crosswind runway option at this facility. Operators working with larger business aircraft or requiring longer landing distances will find this single strip adequate for most midsize and super-midsize jet operations. Its width of 150 feet also provides margin for varied aircraft types.
Is customs clearance available at CYMT?
Chapais Airport does not have customs service onsite. The nearest customs-equipped airport is CYBG, located approximately 164 nautical miles away. Operators arriving from outside Canada or requiring customs clearance need to route through CYBG or another designated port of entry before or after using CYMT. This distance should be factored into fuel planning and routing for any international itinerary touching this airport. Flight crews should confirm current customs procedures and any required advance notice with Canadian border authorities before planning a stop at Chapais.
What is the elevation at Chapais Airport?
Chapais Airport sits at a field elevation of 1,270 feet above sea level. This elevation is a standard planning consideration for performance calculations, particularly for departures during warmer months when density altitude effects are more pronounced. Combined with the airport's single 6,496-foot runway, the elevation figure should be included in takeoff and landing performance planning for any aircraft type. The airport's location in north-central Quebec places it in a region where seasonal temperature swings are significant, further affecting performance margins throughout the year.
What time of year sees the most business aviation traffic at CYMT?
Business aviation activity at Chapais Airport, identified by the ICAO code CYMT, peaks in April and October, each month recording 174 and 177 operations respectively according to FAA TFMSC data. This pattern contrasts with quieter periods in January and December, which see closer to 124 to 126 operations. The spread suggests traffic tied to seasonal demand cycles rather than a single peak summer season common at many airports. Dispatchers planning operations into this field should anticipate somewhat higher activity levels during these spring and fall windows.
What kind of winter weather should operators expect at CYMT?
Chapais Airport experiences an extended winter season with sub-freezing days common across much of the year. December and January each average 30.8 days below 32 degrees Fahrenheit, and February follows closely with 28.3 days. Maximum temperatures during these months remain low, averaging under 17 degrees Fahrenheit in December and around 9 degrees in January. By contrast, summer months such as July reach average highs near 73 degrees Fahrenheit with no days below freezing. Operators should plan for sustained cold-weather operating conditions across the late fall through early spring period at this Quebec airport.
