1. The airspace file that comes with your flight computer is not accurate enough for the WGC. You MUST use the one available on this website to accurately show and avoid forbidden (i.e. penalty) airspace.
    
2.  PENALTY airspace is any airspace coded as Class A, B, C, P (Prohibited), or R (Restricted).
   
   
3. Class A airspace is everything above 18,000' MSL, there is no Class A below that.
   
   
4. Regardless of what your map says, for the purposes of the contest all other PENALTY airspace (B, C, P, and R) areas extend upward to 18,000'MSL.  YOU MAY NEVER OVERYFLY THEM.
   
   
5. Class D airspace is not forbidden, but you must establish radio contact with the facility before you enter it. The top of the airspace is as shown on current charts.
   
   
6. The penalty airspace that defines the border with Mexico does not exactly match the Rio Grande River. It begins a small distance inside the USA. DO NOT depend on visual avoidance of the river. Rely on the airspace file for proper clearance. See this graphic for an example.
   
   
7. Here is a graphic of the Forbidden (Penalty) Airspace
