What does a D Notam pertain to?

A D Notam, or "Domestic Notice to Airmen," specifically pertains to VFR (Visual Flight Rules) information that impacts the safety of flight operations, including details about runway closures and other surface-related advisories. This type of Notam is crucial for pilots to be aware of current conditions and any changes at airports, such as the closure of runways due to maintenance or other obstructions that could affect arrival or departure operations.

VFR pilots, in particular, rely on D Notams to ensure they have accurate and up-to-date information to safely navigate and manage their flight plans. This includes understanding restrictions that could impact their intended routes. Other options presented may involve various aspects of aviation but do not encapsulate the specific function of a D Notam in relation to pertinent flight operations affecting pilots flying under VFR.
