Continuous or dashed double yellow lines that denote the edge of the taxiway. This assists pilots in maintaining situational awareness and prevents the aircraft from straying off the taxiway, especially in low visibility conditions.

A continuous yellow line located in the center of the taxiway used to provide a path for aircraft to follow when taxiing to ensure safe and efficient ground traffic flow.

A surface painted marking located at the holding position for the ILS critical area when visibility is reduced. It informs pilots where to hold to avoid interfering with the ILS system.

Pairs of rectangular white marks on either side of the runway centerline in the touchdown zone, providing visual cues for landing aircraft to aid pilots in choosing the proper touchdown point.

A black sign with yellow writing, providing directional information to specific locations such as runways or terminals, and enhancing airport navigation for pilots.

A yellow sign with black writing, providing pilots with various information about areas or conditions in an airport, like noise abatement procedures or frequency changes.

Series of yellow chevrons painted on areas of the runway not intended for use by aircraft. It safely guides aircraft away from these areas to prevent potential accidents.

Series of yellow dashes indicating the holding position on a taxiway where it intersects with another taxiway. It informs pilots where to stop to give the right-of-way to aircraft or vehicles on the other taxiway.

A sign with numbers indicating the distance of remaining usable runway in thousands of feet. It allows pilots to monitor the amount of runway left during takeoff or rollout after landing.

An 'X' sign or marking indicating that a runway or taxiway is closed. It notifies pilots not to use the specific area for taxiing, takeoff, or landing.

A yellow sign with a series of diagonal stripes indicating the taxiway does not continue, helping to prevent aircraft from accidentally proceeding onto grass or unprepared surfaces.

A red circle with a horizontal white line, indicating that entry onto the taxiway or runway is prohibited. It is a critical safety feature to prevent unauthorized access to active runways or taxiways.

A cone or tetrahedron, usually orange, that shows the direction the wind is blowing. It is essential for pilot decision-making concerning takeoff and landing.

A series of white zigs-zags on the pavement indicating roadway areas intended for vehicle-use only, separating them from aircraft taxiing areas and improving safety on the airfield.

A black sign with a yellow inscription, designating the runway on which an aircraft is currently located. It helps pilots confirm their current position on the airport surface.

A sign indicating a specific ground location where pilots can check the calibration of the aircraft's VOR (VHF Omnidirectional Range) equipment. This is critical for ensuring the accuracy of in-flight navigation instruments.

A sign that serves both to indicate the direction of a taxi route (arrow) and the current location (lettering). It provides a combination of navigational aids to assist pilots in taxiing.

A series of parallel white stripes across the runway that designate the beginning of the runway that is available for landing. It indicates the point beyond which it is safe to touch down when landing.

A surface painted sign with an arrow and identifying letter, indicating the direction of a connecting taxiway. This helps pilots navigate the taxiway system, especially in complex airports.

A yellow sign with a black inscription, typically an arrow and a letter, indicating the direction to a runway exit. It aids pilots in planning the exit from the runway after landing.

A sign with a white inscription on a red background, indicating a required action like a hold position at a runway or critical point. Non-compliance can lead to safety breaches.

A black square sign with yellow lettering that provides information on where the aircraft is currently located on the airport surface, helping with orientation and navigation.

Markings to delineate the ILS critical area to prevent interference with the ILS signals when the ILS is in use. Vehicles and aircraft must avoid this area during critical operations to maintain the integrity of navigational signals.

Two broad white stripes on the runway that serve as visual aiming points for landing aircraft. They are located approximately 1,000 to 1,500 feet from the threshold and help pilots gauge the touchdown zone during landing.
