What is the primary purpose of runway designation signs?

• A. The runway number
• B. The weather
• C. The taxiway direction
• D. The speed limit

Answer: (A)

Runway designation signs exist to identify which runway you’re using by its end’s number, which reflects the runway’s magnetic heading. This helps you confirm you’re entering or departing from the correct runway, especially at busy fields or when there are parallel runways. The number tells you the orientation of that end, and with parallel runways you might see designations like the same number with different letters to tell them apart. These signs don’t convey weather information, they don’t indicate taxiway directions, and they don’t set speed limits.
