Morphology
The compound 'air hole' is directly compositional: combining 'air' (the gas/airflow) + 'hole' (an opening) yields an opening that allows air to pass. This noun+noun construction is cross-linguistically common and follows a straightforward semantic combination, so a B1 learner who knows both words will readily infer the meaning.
Etymology
Air hole comes from the image of an invisible hole in the air where the wind suddenly drops and a plane feels like it falls. Pilots use this simple picture to explain why an aircraft can lose height quickly, so the term means 'a patch of air that makes a plane lose height'.
