(a) On taxiways that intersect the beginning of the takeoff runway, only the designation of the takeoff runway may appear on the sign as shown in FIG 2.3.25, while all other signs will have the designation of both runway directions. 2.3.20 Airport Marking Aids and Signs FIG 2.3.26 Holding Position Sign for a Taxiway that Intersects the Intersection of Two Runways FIG 2.3.27 Holding Position Sign for a Runway Approach Area (b)If the sign is located on a taxiway that intersects the intersection of two runways, the designations for both runways will be shown on the sign along with arrows showing the approximate alignment of each runway as shown in FIG 2.3.26. In addition to showing the approximate runway alignment, the arrow indicates the direction to the threshold of the runway whose designation is immediately next to the arrow. (c)A runway holding position sign on a taxiway will be installed adjacent to holding position markings on the taxiway pavement. On runways, holding position markings will be located only on the runway pavement adjacent to the sign, if the runway is normally used by air traffic control for “Land, Hold Short” operations or as a taxiway. The holding position markings are described in paragraph 2.3.5, Holding Position Markings. 2. Runway Approach Area Holding Position Sign. At some airports, it is necessary to hold an aircraft on a taxiway located in the approach or departure area for a runway so that the aircraft does not interfere with operations on that runway. In these situations, a sign with the designation of the approach end of the runway followed by a “dash” (.) and letters “APCH” will be located at the holding position on the taxiway. Holding position markings in accordance with paragraph 2.3.5, Holding Position Markings, will be located on the taxiway pavement. An example of this sign is shown in FIG 2.3.27. In this example, the sign may protect the approach to Runway 15 and/or the departure for Runway 33. Airport Marking Aids and Signs 2.3.21 FIG 2.3.28 Holding Position Sign for ILS Critical Area FIG 2.3.29 Sign Prohibiting Aircraft Entry into an Area 3. ILS Critical Area Holding Position Sign. At some airports, when the instrument landing system is being used, it is necessary to hold an aircraft on a taxiway at a location other than the holding position described in paragraph 2.3.5, Holding Position Markings. In these situations the holding position sign for these operations will have the inscription “ILS” and be located adjacent to the holding position marking on the taxiway described in paragraph 2.3.5. An example of this sign is shown in FIG 2.3.28. 4. No Entry Sign. This sign, shown in FIG 2.3.29, prohibits an aircraft from entering an area. Typically, this sign would be located on a taxiway intended to be used in only one direction or at the intersection of vehicle roadways with runways, taxiways or aprons where the roadway may be mistaken as a taxiway or other aircraft movement surface. NOTE. The holding position sign provides the pilot with a visual cue as to the location of the holding position marking. The operational significance of holding position markings are described in the notes for paragraph 2.3.5, Holding Position Markings. 2.3.22 Airport Marking Aids and Signs FIG 2.3.30 Taxiway Location Sign FIG 2.3.31 Taxiway Location Sign Collocated with Runway Holding Position Sign 2.3.9. Location Signs a. Location signs are used to identify either a taxiway or runway on which the aircraft is located. Other location signs provide a visual cue to pilots to assist them in determining when they have exited an area. The various location signs are described below. 1. Taxiway Location Sign. This sign has a black background with a yellow inscription and yellow border as shown in FIG 2.3.30. The inscription is the designation of the taxiway on which the aircraft is located. These signs are installed along taxiways either by themselves or in conjunction with direction signs or runway holding position signs. (See FIG 2.3.35 and FIG 2.3.31.)Airport Marking Aids and Signs 2.3.23 FIG 2.3.32 Runway Location Sign FIG 2.3.33 Runway Boundary Sign 2. Runway Location Sign. This sign has a black background with a yellow inscription and yellow border as shown in FIG 2.3.32. The inscription is the designation of the runway on which the aircraft is located. These signs are intended to complement the information available to pilots through their magnetic compass and typically are installed where the proximity of two or more runways to one another could cause pilots to be confused as to which runway they are on. 3. Runway Boundary Sign. This sign has a yellow background with a black inscription with a graphic depicting the pavement holding position marking as shown in FIG 2.3.33. This sign, which faces the runway and is visible to the pilot exiting the runway, is located adjacent to the holding position marking on the pavement. The sign is intended to provide pilots with another visual cue which they can use as a guide in deciding when they are “clear of the runway.” 2.3.24 Airport Marking Aids and Signs FIG 2.3.34 ILS Critical Area Boundary Sign 4. ILS Critical Area Boundary Sign. This sign has a yellow background with a black inscription with a graphic depicting the ILS pavement holding position marking as shown in FIG 2.3.34. This sign is located adjacent to the ILS holding position marking on the pavement and can be seen by pilots leaving the critical area. The sign is intended to provide pilots with another visual cue which they can use as a guide in deciding when they are “clear of the ILS critical area.” 2.3.10. Direction Signs a.Direction signs have a yellow background with a black inscription. The inscription identifies the designation(s) of the intersecting taxiway(s) leading out of the intersection that a pilot would normally be expected to turn onto or hold short of. Each designation is accompanied by an arrow indicating the direction of the turn. |
