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

• A. Altimeters
• B. Ceilometers
• C. Automated Land Observing System (ALOS)
• D. Airport Weather Information System (AWIS)

Answer: (A)

Wind indicators show the surface wind direction and speed, which pilots use for takeoff, landing, and runway alignment. The other essential surface instrument is the altimeter, which provides the local barometric pressure reading that pilots use to set their altimeter and understand altitude relative to the ground. Having wind information together with the altimeter setting gives pilots the immediate, critical weather data needed for safe operations at the airport. Ceilometers measure cloud height but aren’t typically part of the basic surface weather instrument set; ALOs and AWIS are systems, not single instruments used in the basic terminal kit.
