Restricted Airspace – Know Where It Lies!

Dear Editor,

In a recent six-month span, the Moose Jaw military air traffic controllers have recorded five separate incidents of light civilian VFR aircraft violating CYR 303, a restricted military training area near Mossbank, Saskatchewan, used by 431 (Air Demonstration) Squadron, the “Snowbirds.” In one startling case, one of these VFR aircraft came very close to a jet formation that was practicing aerobatic manoeuvers. All aircraft were at the same altitude and none of the Snowbird pilots detected the conflicting aircraft.

While the Moose Jaw situation may be considered unique, it can nevertheless be used to remind all pilots of the need to prepare thoroughly prior to commencing any VFR flight. This should include the following:

1. in-depth analysis of the proposed route (including review of NOTAMs);
2. knowledge of the territory to be overflown (particularly Restricted [CYR] and Advisory [CYA] areas in Class F airspace); and,
3. possession of all applicable VFR charts.

While these three simple rules will seem obvious to most, the incidents we recorded lead us to believe some pilots do not follow them. No matter where you live, and where you fly, odds are there are CYAs and CYRs near you. By following the three simple rules stated above, you will avoid such hazardous areas and ensure you, your passengers, and fellow aviators have a safe and enjoyable flight.
