3	ILS Critical Area Holding Position Sign ATC may hold you at this sign, on a taxiway, when the instrument landing system is being used at the airport. Aircraft taxiing beyond this point may interfere with the ILS signal to approaching aircraft. Ref. AIM Para. 2-3-8
4
5	Runway Boundary Sign This sign faces the runway and is visible to pilots exiting the runway. It is located next to the yellow holding position markings painted on the taxiway pavement. Taxi past this sign to be sure you are clear of the runway. Ref. AIM Para. 2-3-9
6
7	Runway Approach Area Holding Position Sign If instructed by ATC, hold here until cleared to cross. Taxiing past this sign may interfere with operations on the runway. (In this case, aircraft arriving to runway 15 or departing from runway 33.) It is located next to the yellow holding position markings painted on the taxiway pavement. Ref. AIM Para. 2-3-8
8
9	Taxiway Location Sign Indicates the taxiway you are on. (May be co-located with direction signs or runway holding position signs, as shown in graphic.) Ref. AIM Para. 2-3-9
10
11	Runway Holding Position Sign If this is your departure runway, or if instructed by ATC, hold here. In this example, the threshold for runway 15 is to your left and the threshold for runway 33 is to your right. This sign is located next to the yellow holding position marking painted on taxiways that intersect runways and on runways that intersect other runways. Ref. AIM Para. 2-3-8
12
13	ILS Critical Area Boundary Sign Located next to the ILS holding position markings and is seen by pilots leaving the ILS critical area. When ILS approaches are in use, be sure your aircraft has passed beyond this sign before stopping on the taxiway. Ref. AIM Para. 2-3-9
14
15	Holding Position and Location Signs In this example, you are on taxiway Alpha approaching the intersection of runways 5-23 and 9-27. Runway 5 threshold is to the left. Runway 23 threshold is to the right. Runway 9 threshold is ahead and to the left. Runway 27 threshold is behind and to the right. Ref. AIM Para. 2-3-8 and 2-3-9
16
17	Direction Signs and Location Sign The black location sign indicates you are on taxiway Alpha. The yellow direction signs indicate the direction of intersecting taxiways. In this example, taxiway Charlie is to the left, Alpha takes a turn to the right ahead, and Charlie is to the immediate right. Ref. AIM Para. 2-3-9 and 2-3-10
18
19	No Entry Sign Indicates an area prohibited to aircraft. Do not enter this area. This sign would be found at the entrance to a one-way taxiway or at the intersection of a road intended for vehicles. Ref. AIM Para. 2-3-8
20
21	Inbound Destination Sign Indicates a destination on the airport, with an arrow pointing out the direction to that destination. In this example, the military installation is to your right. Other information signs are “Cargo”, “Term” (Terminal), “Ramp”, etc. Ref. AIM Para. 2-3-11
22
23	Outbound Destination Sign Indicates a common taxi route to runway(s), with an arrow pointing out the direction of the taxi route. A dot (.) separates two destinations. In this example, runways 27 and 33 are to your right. Ref. AIM Para. 2-3-11
24
25	Runway Holding Position Markings This painted marking is found on taxiways at runway intersections and indicates where an aircraft is to stop. The solid lines are on the side where the aircraft is to hold and the dashed lines are always on the side toward the runway. Do not cross the markings until cleared. Ref. AIM Para. 2-3-5
26
27	Runway Location Sign Identifies runway on which your aircraft is located. Ref. AIM Para. 2-3-9
28
29	Direction Sign for Runway Exit Indicates an exit from a runway. Located just prior to the intersection, on the same side of the runway as the exit. Ref. AIM Para. 2-3-10
30
31	Taxiway Ending Marker Indicates the taxiway does not continue. Located on the far side of the intersection. Ref. AC 150/5340-18C
32
33	Holding Position Marking for ILS Indicates the boundary of the ILS critical area. Don’t cross unless cleared. When exiting the area, a yellow ILS Critical Area Boundary sign will be adjacent this marking. All parts of your aircraft must cross this marking to be clear of the ILS critical area. Ref. AIM Para. 2-3-5
34
35	Closed Runway and Taxiway Marking Indicates a closed runway or taxiway. On a permanently closed runway, it will be placed at each runway end and at 1,000 ft. intervals. It will also be placed at each entrance of a permanently closed taxiway. A raised-light X, plywood or fabric may be used in lieu of a pavement marking. Ref. AC 150/5340-IH
