How can a pilot determine if a runway is closed?

The most reliable method for a pilot to determine if a runway is closed is by checking NOTAMs (Notices to Airmen) and listening to ATIS (Automatic Terminal Information Service). NOTAMs provide up-to-date information about various aviation-related situations, including runway closures, obstructions, and other critical airfield information that may not be immediately visible. ATIS broadcasts current weather conditions, runway usage, and other relevant airport information, including any notices of closed runways.

Using NOTAMs and ATIS ensures that pilots are informed about any changes that might affect their flight operations and safety, as this information is officially distributed and maintained by the aviation authorities. This means that a pilot can rely on this source to have the most accurate and timely information concerning the status of runways.

In contrast, observing other aircraft on the runway may not provide an accurate assessment of whether the runway is officially closed. Runway lights might indicate operational status, but they can also be malfunctioning or non-standard in certain situations. Reading airport signposts can be useful, but it may not always clearly indicate closure when the signs are not specifically designed to convey that information. Therefore, relying on NOTAMs and ATIS is the most comprehensive and effective way to ascertain
