FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsMedium

While reviewing a sectional chart, a remote pilot notices a magenta-bordered area labeled 'ALERT AREA' with an A-number. What should the pilot understand about this airspace?

  1. AIt contains a high volume of pilot training or unusual aerial activity, and pilots should exercise extra caution
  2. BIt automatically converts to Class G airspace after sunset
  3. CIt requires the same ATC authorization process as Class B airspace
  4. DIt is closed to all civil aircraft including UAS at all times
Show answer & explanation

Correct answer: A. It contains a high volume of pilot training or unusual aerial activity, and pilots should exercise extra caution

Alert areas advise pilots of airspace that may contain a high volume of pilot training or an unusual type of aerial activity; there is no regulatory requirement to avoid them, but extra vigilance is advised for all aircraft, manned and unmanned.

Why the other options are wrong

  • B. Alert area status has nothing to do with time of day or lighting conditions.
  • C. Alert areas do not require the ATC authorization process that controlled airspace does.
  • D. Alert areas are not closed airspace; they simply warn of increased activity.

Alert Area

Charted airspace that may contain a high volume of pilot training activities or unusual aerial activity; all pilots are advised to use extra caution.

  • Depicted on sectionals as an A-numbered area
  • No special ATC authorization required to enter
  • Activity level varies; caution advised, not prohibition
  • Common near flight training bases or gliderports

Memory trick: Alert = 'Look Alert!' extra training traffic ahead
