Frequently asked questions
What customs procedure applies at CZBM?
Bromont (Roland Désourdy) Airport, ICAO code CZBM, is listed as an airport of entry under an AOE/15 designation. This means customs clearance is available on site, but the facility is restricted to processing a maximum of fifteen persons per aircraft. Crews planning a border crossing into this Quebec airport need to confirm passenger count fits within that ceiling before filing. Operators exceeding that limit should plan clearance through an alternate airport of entry instead.
How long is the main runway at CZBM?
CZBM's primary runway, 05/23, is a paved asphalt surface measuring 5,000 feet long and 100 feet wide. This is the only hard-surfaced runway at Bromont (Roland Désourdy) Airport and defines the maximum paved landing distance available at the field. A second runway, 05R/23L, exists as a 3,200-foot grass strip at 320 feet wide, offering a much wider but unpaved alternative. Jet and turboprop operators should plan around the 5,000-foot asphalt strip as the primary option.
What does business aviation traffic look like at Bromont (Roland Désourdy) Airport?
Bromont (Roland Désourdy) Airport recorded 817 business aviation operations against a total of 934 annual operations in 2025, according to FAA TFMSC data. Since CZBM is a Canadian field, this figure reflects cross-border traffic as seen by the FAA rather than the airport's full operational count. Monthly volumes vary widely, ranging from a low of 12 operations in September to a high of 137 in October. Dispatchers should treat these numbers as a cross-border traffic indicator rather than a measure of total airport activity.
Is CZBM's traffic seasonal?
Yes, traffic at CZBM shows a notable seasonal pattern rather than a flat year-round distribution. Business aviation operations peak in May, July, and October, with October alone recording 137 operations compared to single-digit and low double-digit counts in September and February. This variation matters for planning purposes at Bromont (Roland Désourdy) Airport, since ramp and services demand will differ significantly between peak and shoulder months. Crews scheduling flights outside these peak windows may find quieter conditions on the field.
What winter conditions should crews expect at Bromont (Roland Désourdy) Airport?
Bromont (Roland Désourdy) Airport experiences cold winters with substantial snow days, based on climate normals for the site. December through February each average around 27 to 30 days per month with temperatures below 32°F, and each of those months sees roughly 3.7 to 3.8 days with an inch or more of snow. Maximum temperatures in January average just 23.7°F, rising only slightly through February and March. Crews operating into CZBM during these months should plan for cold-weather procedures and possible snow removal delays on the paved runway.
