If there is no sensing capability available on the runway complex, weather technicians may obtain data using backup methods at what location?

• A. Control Tower
• B. AOL
• C. Observing
• D. Runway Complex

Answer: (C)

When the runway’s sensing equipment isn’t available, weather data must still be collected through an alternate, reliable source. The observing location is the designated spot where weather personnel or backup systems can perform manual observations or access different measurement sources to maintain continuous data, including wind, visibility, cloud cover, ceiling, and precipitation. This ensures you have timely, usable weather information even if the primary runway sensors are down. The control tower mainly handles air traffic control, not routine weather observations; AOL isn’t the standard backup observation point in this context; and the runway complex houses the primary sensing equipment, so the backup data comes from the observing location.
