Surface painted holding position signs feature white numerals displaying the runway designators on a red background. At an intersection with multiple runways, white arrows are also used. Depending on the width of the taxiway, a single surface painted holding position sign may be positioned centered over the taxiway, on the left side of the centerline, or on both the left and right sides of the taxiway centerline.
Surface painted taxiway direction signs have a yellow background with a black inscription that includes a directional arrow. These markings are used to provide directional guidance at taxiway intersections whenever it is impossible to install a normal taxiway directional sign or when a particularly troublesome intersection requires supplemental directional guidance to reduce pilot confusion.
Markings indicating a left turn are painted left of centerline, while markings indicating a right turn are painted right of centerline. Surface painted location signs have a black background with a yellow inscription. When necessary, these markings are used to supplement location signs to assist pilots in confirming which taxiway they are on.
Surface painted location signs are painted right of the taxiway centerline. Non-Movement Area Boundary Markings. Non-movement area boundary markings identify the area of the airport under air traffic control, also known as the movement area, from those areas not under air traffic control or the non-movement area.
These markings consist of two yellow lines, one solid and one dashed. The solid line is positioned on the non-movement area side. Pilots are expected to contact the air traffic control tower for taxi instructions prior to passing over the non-movement area boundary marking. Some airports utilize a surface movement guidance control system plan to allow for low visibility taxi operations when runway visual range is less than 1, feet.
As part of this plan, geographic position markings are repeatedly painted along the designated taxi route. A geographic position marking consists of a pink circle outlined by a white ring and a black border.
The circle also contains a designation, either a number or a number and letter combination, painted in black. The designation corresponds to the sequential position of the marking along the taxi route. These markings allow pilots to more accurately make position reports to air traffic control and confirm holding spots during periods of low visibility. Accordingly, geographic position markings are co-located with a taxiway holding position marking.
The markings are positioned left of the taxiway centerline in the direction of taxi. Federal Aviation Regulation Part One method of testing the equipment is to utilize a VOR receiver checkpoint at an airport. To find out which airports near you have a VOR receiver checkpoint, search the appropriate chart supplement formally known as the Airport Facilities Directory.
A list of VOR receiver checkpoints and test facilities by state can be found toward the back of the book. VOR receiver checkpoint markings consist of a yellow arrow aligned in the direction of the VOR facility, and is encompassed by a yellow circle.
As needed the circle may be given a white border and a black interior to add further contrast. A sign is also typically associated with the marking to provide pilots with additional pertinent information for conducting the VOR receiver test.
There are several runways at civilian airports in the Midwest that have arresting cables installed for military aircraft. These cables are marked by a series of 10 foot wide yellow circles spanning the width of the runway. Vehicle roadway markings are used to define a path for vehicles on paved areas also used by aircraft to reduce the probability of collisions. Vehicle roadway markings consist of a solid white edge line and white dashed line to delineate lanes.
Alternatively, airports may choose to enhance the vehicle roadway markings by using a white and black zipper pattern in lieu of solid lines. You must be logged in to post a comment.

The Basics While all runways share two common markings the centerline and designator , a taxiway is really only guaranteed to have one, the centerline.
Holding Position Markings Holding position markings play a vital role in keeping aircraft adequately separated at intersections and other safety critical areas. Runway Holding Position Markings On Taxiways The first, and by far the most common location, is on a taxiway at the intersection with a runway.
Runway Holding Position Markings On Runways Runway holding position markings can also be found on intersecting runways whenever that runway is used for land and hold short operations or when occasionally utilized for taxi operations. Runway Approach Area Holding Position Markings In some instances, a taxiway may not intersect with the runway itself, but instead, intersect with a runway approach area or the runway safety area.
Taxiway Holding Position Markings At airports with an air traffic control tower, taxiway holding position markings are often utilized anywhere aircraft are normally requested to hold, other than on or at a runway. Surface Painted Signs Surface painted signs come in a variety of shapes, sizes and colors.
Surface Painted Holding Position Signs In , FAA made surface painted holding position signs mandatory at all commercial service airports in an effort to further combat runway incursions and wrong runway takeoffs. Non-Movement Area Boundary Markings Non-movement area boundary markings identify the area of the airport under air traffic control, also known as the movement area, from those areas not under air traffic control or the non-movement area.
Geographic Position Markings Some airports utilize a surface movement guidance control system plan to allow for low visibility taxi operations when runway visual range is less than 1, feet. Arresting Cable Marking There are several runways at civilian airports in the Midwest that have arresting cables installed for military aircraft.
Vehicle Roadway Markings Vehicle roadway markings are used to define a path for vehicles on paved areas also used by aircraft to reduce the probability of collisions.

The letters 'O', 'I' and 'X' are not used. At large airports where there are more taxiways than letters of the alphabet, double letter designators may be used for minor taxiways or taxiway stubs.
If only one type is present, it will always be the former. Where there is more than one RTHP, all the additional ones will be of the second type.
