Which signs are characterized by a black background, yellow inscription, and a yellow border?

Runway and taxiway location signs are indeed identified by a black background with yellow inscriptions and a yellow border. This color scheme is specifically designed for visibility and quick identification, which is crucial for pilots as they navigate the airport environment. The black background ensures that the yellow lettering stands out sharply, making it easier for pilots to read the signs quickly, especially during night operations or in low-visibility conditions.

Runway and taxiway location signs serve to inform pilots of their position on the airfield and provide important information about runways and taxiways. This allows for efficient ground operations and enhances safety, as pilots can confirm their location and ensure they are following the correct routes.

Other signs, such as safety information, regulatory, and information signs, have different color schemes and meanings that do not match this specific description. Each type of sign has its own unique color coding established by aviation regulations to convey different messages and instructions to pilots.
