8.  Mandatory Instruction Signs 

a. 

These signs have a red background with a white 

inscription and are used to denote: 

1. 

An entrance to a runway or critical area; and 

2. 

Areas where an aircraft is prohibited from 

entering. 

b.  Typical mandatory signs and applications 

are: 

1.  Runway Holding Position Sign. 

This sign 

is located at the holding position on taxiways that 
intersect a runway or on runways that intersect other 

runways. The inscription on the sign contains the 
designation of the intersecting runway, as shown in 
FIG 2

3

24. The runway numbers on the sign are 

arranged to correspond to the respective runway 
threshold. For example, “15

33” indicates that the 

threshold for Runway 15 is to the left and the 
threshold for Runway 33 is to the right. 

(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.
