How often is a new CFS published?

How often is a new CFS published?

• A. 30 days
• B. 56 days
• C. 90 days
• D. 120 days

Answer: (B)

The main idea is the publishing cycle of the Canadian Flight Supplement (CFS). The CFS is the official source of current aeronautical information for Canada, including airport data, procedures, and temporary restrictions. It is issued on a fixed 56-day cycle, which keeps information reasonably fresh without overwhelming the publication process. Pilots should consult the latest edition before flight because details can change between cycles, and using outdated data can create safety or operational risks. Intervals like 30, 90, or 120 days would either require overly frequent updates or allow information to become too stale, whereas 56 days is the standard cadence.
