NAV CANADA 26 MAY 16 AERONAUTICAL INFORMATION CIRCULAR 11/16 Introduction DEPICTION OF FIVE-NAUTICAL-MILE BUFFERS AROUND SPECIAL USE AIRSPACE CONTAINED WITHIN CANADIAN FLIGHT INFORMATION REGIONS (Supersedes AIC 19/15) To assist in efficiently planning routes that avoid restricted areas in Canadian flight information regions (FIRs), NAV CANADA is providing customers with depictions of currently published special use airspace that also show a surrounding five-nautical-mile buffer zone through which flight will not be permitted. The depictions are intended to provide a visual representation for operators to consider when preparing flight plans involving operations at and above flight level (FL) 290. This aeronautical information circular (AIC) supplements the information contained in AIC 19/15 with three additional restricted areas (CYR664, CYR665, and CYR666) and associated five-nautical-mile buffer zones from the Montreal FIR. The information provided is intended for publication in the Fall 2016 AIP Canada (ICAO). Background As described in the TC AIM TP 14371E, special use airspace may be classified as Class F advisory or as Class F restricted within Canadian Domestic Airspace (CDA). In accordance with International Civil Aviation Organization (ICAO) requirements, special use airspace may also be classified as a danger area when established over international waters, but controlled by Canadian air traffic control (ATC). Class F airspace is described in the Designated Airspace Handbook (DAH, TP 1820E) and depicted on HI or LO charts, as applicable. Canadian controllers apply a five-nautical-mile separation minimum to en route aircraft being provided with air traffic service (ATS) surveillance service from the boundary of special use airspace. NAV CANADA customers have indicated that it would be beneficial to have visual indication of this buffer zone. Flight Planning Considerations The depicted buffers around the boundaries of special use airspace that is at or above flight level (FL) 290 have been constructed using parallel lines measuring five nautical miles from the straight segments and using five-nautical-mile arcs from the curved portions. Operators are advised that the arc points represented as coordinates of latitude and longitude are not to be used as routing waypoints.
