What do directional signs provide for pilots?

Directional signs play a crucial role in providing pilots with essential information about their current location and the direction they need to take on the airfield. These signs are strategically placed to help pilots navigate effectively and maintain situational awareness while taxiing.

By displaying information such as the names of runways, taxiways, and other critical points on the airfield, directional signs enable pilots to orient themselves within the airport environment. This capability is especially vital in complex airfields where it can be easy to become disoriented. Thus, the correct choice highlights the primary function of directional signs in aiding pilots by providing necessary information for safe and efficient navigation.
