FAA Flight Instructor Airplane (FIA)Navigation and AirspaceEasy

A student pilot notices an area on the sectional chart labeled with an 'A' and a number (e.g., 'A-123'), described in the legend as containing a high volume of pilot training or unusual aerial activity. This is best identified as:

  1. Aan Alert Area
  2. Ba Military Operations Area
  3. Ca Restricted Area
  4. Da National Security Area
Show answer & explanation

Correct answer: A. an Alert Area

Alert Areas are depicted on sectional charts to inform pilots of areas with a high volume of pilot training or unusual aerial activity. They are non-restrictive, but pilots should exercise vigilance since no special clearance is required.

Why the other options are wrong

  • B. MOAs are labeled with names, not 'A-' designators, and are used for military training maneuvers.
  • C. Restricted Areas are labeled 'R-' and require permission to enter.
  • D. NSAs are depicted with dashed blue lines and a note, not an 'A-' number.

Alert Area

A type of special use airspace depicted with an 'A-' designator, indicating high volumes of pilot training or unusual aerial activity; entry is not restricted but caution is advised.

  • No ATC clearance required to enter.
  • Both civilian and military traffic must see-and-avoid.
  • Charted with a magenta or blue outline and 'A-' number.

Memory trick: 'Alert = A for Awareness, not Authorization.'
