Information Signs
Information signs identify a specific destination, location, frequency, or routing information to pilots. The inscriptions incorporate arrows, numbers, letters, or pictographs to convey instructions or to identify specific areas.
Location Sign
A location sign has a yellow inscription on a black background and is used to identify the taxiway that the aircraft is on or entering. A location sign never contains arrows.
Direction Sign
A direction sign has a black inscription on a yellow background and is used to identify the intersecting taxiways toward which an aircraft is approaching. The sign is, whenever practicable, positioned on the left-hand side of the taxiway and prior to the intersection. A direction sign will always contain arrows to indicate the approximate angle of intercept. Direction signs are normally used in combination with location signs to provide the pilot with position information.
Runway Exit Sign
A runway exit sign has a black inscription on a yellow background and is used to identify a taxiway that exits a runway. The sign is positioned prior to the intersection on the same side of the runway as the exit. The sign will always contain an arrow and will indicate the approximate angle at which the taxiway intersects the runway. When a taxiway crosses a runway, a sign will be positioned on both sides of the runway. Runway exit signs may be omitted in cases where aircraft do not normally use the taxiway to exit or in cases of one-way taxiways.
Destination Sign
A destination sign has a black inscription on a yellow background and is used to provide general guidance to points on the airfield. These signs will always contain arrows. The use of destination signs will be kept to a minimum. Airports with a good direction sign layout will have little need for destination signs.
Other Information Sign
Other information signs have a black inscription on a yellow background and include information such as stand identification, parking areas and frequency.
