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. 

b. Except as noted in subparagraph e, each taxiway designation shown on the sign is accompa- nied by only one arrow. When more than one taxiway designation is shown on the sign, each designation and its associated arrow is separated from the other 

taxiway designations by either a vertical message divider or a taxiway location sign as shown in FIG 2 − 3 − 35. 

c. Direction signs are normally located on the left prior to the intersection. When used on a runway to indicate an exit, the sign is located on the same side of the runway as the exit. FIG 2 − 3 − 36 shows a direction sign used to indicate a runway exit. 

d. The taxiway designations and their associated arrows on the sign are arranged clockwise starting from the first taxiway on the pilot’s left. (See FIG 2 − 3 − 35.) 

e. If a location sign is located with the direction signs, it is placed so that the designations for all turns to the left will be to the left of the location sign; the designations for continuing straight ahead or for all turns to the right would be located to the right of the location sign. (See FIG 2 − 3 − 35.) 

f. When the intersection is comprised of only one crossing taxiway, it is permissible to have two arrows associated with the crossing taxiway, as shown in FIG 2 − 3 − 37. In this case, the location sign is located to the left of the direction sign.
