The basic weather instrument equipment for terminals includes wind indicators and which instrument?

• A. Ceilometers
• B. Altimeters
• C. ALOS
• D. AWIS

Answer: (B)

Wind indicators give you the current wind direction and speed on the field, while the other essential instrument for the terminal weather set is an altimeter. The altimeter measures atmospheric pressure to determine altitude and provides the altimeter setting (QNH) that pilots use to maintain the correct height during approaches and landings. Ceilometers measure cloud base, which is valuable but not as fundamental to the basic on-field weather instrument pairing as altitude reference. AWIS is a weather information system, not a single instrument, and ALOS isn’t part of the standard basic instrument set. So the altimeter is the best match with wind indicators for terminal weather instrumentation.
