Class F identification code

Every Class F area has a four-part code: CY + type + region + activity (TC AIM RAC 2.8.6.1). Any CYA, CYR or CYD code is Class F. Entry rules: airspace-reservation-zones.

Code (in order):

  1. CY = Canada
  2. Type letter: R restricted, A advisory, D danger
  3. Three-digit region number
  4. Activity letter in brackets, advisory areas only

Example: CYA113(A) = Canada, advisory, area 113 (BC), acrobatic.

Code Type Meaning
CYA Advisory Activity may be under way, enter with caution (RAC 2.8.6.3)
CYR Restricted No entry without the user agency's permission (CAR 601.04(2))
CYD Danger, international waters Hazardous activity (RAC 2.8.6.2)
Region number Region
101-199 BC
201-299 AB
301-399 SK
401-499 MB
501-599 ON
601-699 QC
701-799 NB/NS/PE/NL
801-899 YT
901-999 NT/NU
Activity letter (advisory only) Activity

Trap: a NOTAM closure (forest fire, Aeronautics Act s.5.1) carries no CY code and is not Class F (RAC 2.8.6.4); only CYA codes take a bracketed activity letter.
