What is the full form of ASOS in aviation?

The full form of ASOS in aviation is the Automated Surface Observation System. ASOS is a critical system used at airports and various weather stations to provide real-time weather information. It automatically collects, processes, and disseminates observational data about surface weather conditions. This includes vital information such as temperature, humidity, wind speed and direction, visibility, cloud cover, and barometric pressure.

ASOS plays a key role in enhancing aviation safety and efficiency by providing accurate weather data that pilots and air traffic controllers rely on during flight operations. The automated nature of ASOS allows for continuous monitoring and reporting without the need for human observation, which is essential for timely information dissemination.

Other options mention systems that either do not exist or do not pertain accurately to the context of aviation meteorology, reinforcing the correctness of the choice of Automated Surface Observation System as the right answer in this case.
