What type of signage has no arrows and is used to identify runway locations?

The correct answer highlights the specific role of location signs in an airport setting. These signs are essential for pilots and ground personnel as they convey precise information, indicating the current position of an aircraft on the airport premises, particularly on the taxiway and runway areas.

Location signs are characterized by their lack of directional arrows, focusing solely on identifying the location. They typically feature a black background with yellow lettering, which enhances visibility and clarity, especially in low-light conditions. Such clear identification is crucial for effective ground movement and safety, as it ensures that pilots are aware of where they are on the airfield, thereby preventing potential mishaps.

Other types of signage serve different purposes. For example, direction signs are used to guide pilots toward runways or taxiways with arrows indicating the direction to follow. Designation signs identify specific runways or taxiways, usually denoting their names with alphanumeric codes. Information signs provide additional details, such as indicating the location of services or facilities. However, none of these signs are solely focused on identifying an aircraft's current location without directional indicators, which is why location signs are the correct answer in this context.
