QUESTIONA taxiway at an airport was closed this morning for construction. In which source would a remote pilot expect to find this time-critical information before flying there?

  1. AA Notice to Airmen (NOTAM)
  2. BThe current Chart Supplement U.S.
  3. CThe sectional chart legend
Show the answer and explanation

Correct answer: A. A Notice to Airmen (NOTAM)

  • A — correct NOTAMs carry time-critical information that is temporary or not known far enough in advance to publish, and the study guide lists taxiway and runway closures and construction among their contents.
  • B — incorrect The Chart Supplement U.S. is revised every 56 days, so a closure that began today would not appear in it.
  • C — incorrect The chart legend explains chart symbols; sectional charts are revised only semiannually and do not carry same-day closures.

BACKGROUND

The study guide defines a Notice to Airmen (NOTAM) as time-critical aeronautical information that is of a temporary nature or not sufficiently known in advance to permit publication on aeronautical charts or in other operational publications, and that receives immediate dissemination through the NOTAM system. NOTAMs contain information such as taxiway and runway closures, construction, communications, and changes in the status of navigational aids. A remote pilot can use this information to make an informed decision about where and when to operate the small unmanned aircraft. The study guide says pilots should check for NOTAMs that could affect their intended flight before any flight.

STUDY TIP

When the question involves something temporary or recent at an airport, the answer is almost always the NOTAM system.

KEY POINTS

  • NOTAMs carry temporary, time-critical information disseminated immediately.
  • They include taxiway and runway closures and construction.
  • Check NOTAMs before every flight near an airport.
