FAA Aircraft Dispatcher Practice Exam

What type of information is typically contained in D NOTAMs?

1. Details about navigational aid status

2. Weather updates

3. Runway closures

4. Flight schedule changes

The correct answer is: Details about navigational aid status

D NOTAMs, or Dissemination NOTAMs, contain information pertinent to navigation and operational status regarding navigational aids and services. This type of NOTAM is essential for pilots and flight dispatchers as it provides critical updates on the condition of navigational aids, including whether they are operational or out of service. The emphasis on navigational aid status helps ensure safe navigation during flight operations, as any malfunction or change may significantly affect flight planning and execution. Pilots rely on D NOTAMs to determine the usability of navigation resources, which is crucial for both visual and instrument flight. Other types of information, such as weather updates, runway closures, or flight schedule changes, fall under different categories of NOTAMs. Weather updates would more likely be found in aviation weather reports or specific weather-related NOTAMs. Runway closures might be detailed in F NOTAMs, which are operationally focused on airfield conditions. Flight schedule changes are typically communicated through airline channels rather than NOTAMs. Thus, D NOTAMs specifically center on navigational aid information, which is why the answer is focused on that area.
