A Restricted Area on a sectional chart is labeled with which prefix, and what color is the border hatching?
A'R-' prefix (e.g., R-2515) with blue hatched border✓
B'P-' prefix with magenta hatched border
C'W-' prefix with green hatched border
Why →Restricted areas use 'R-' prefixed identifiers and are depicted with blue hatched borders on sectional charts. Altitude, time of use, and controlling agency are listed in the chart margins. Flight in active restricted areas requires authorization from the controlling agency.
The trap →The P- prefix answer confuses R- (restricted) with P- (prohibited). The W- prefix answer invents a color that is not used for restricted areas.
Field note →Warning Areas use 'W-' and are typically offshore; they look similar to restricted areas but cover international waters where U.S. restrictions cannot apply.
