Which sign is a runway designation sign at a runway extremity indicating a runway holding position?

• A. Runway designation sign (extremity)
• B. No Entry Sign
• C. Obstacle Free Zone Sign
• D. Direction Sign Array

Answer: (A)

Runway designation signs at the far end of a runway are placed so pilots see the runway’s numeric identity from the opposite direction. This sign tells you which runway you’re looking at when you’re approaching from the other end, helping confirm you’re about to use the correct runway and understand your orientation on the airfield. It’s distinct from signs that prohibit entry, mark obstacle-free zones, or provide taxiway/runway directions; those serve different purposes. So, the sign located at the runway extremity that displays the runway number is the one that identifies the runway from the opposite direction.
