How Informative

Morphology
The meaning is directly derivable from combining 'air' (moving gas/wind) with 'sock' (a cone-like fabric tube used to show wind direction): essentially a 'sock for air' that shows wind direction and strength. This is a regular noun–noun compositional pattern, so a B1 learner who knows both constituent senses can infer the MWE's meaning.
Etymology
Air sock is a cloth cone like a big sock that fills with air and points the way the wind blows. That's why pilots and ground staff use it to check wind 'direction' and 'strength' before takeoff.
