Definition
An open, forward-facing duct mounted on an aircraft that uses the airplane's forward motion to capture outside air and direct it into a system that needs airflow, such as engine induction, carburetor intake, oil cooler, or cabin ventilation.
Plain English
A small open inlet on the outside of the airplane that catches air as the plane moves forward and channels it inside to where it is needed.
Context Anchor
Seen during preflight inspections, aircraft system descriptions, and discussions of cooling or ventilation airflow.
Derivation
Scoop comes from the Middle Dutch schoepe, meaning a vessel for catching or lifting something. An air scoop literally scoops air from the slipstream as the aircraft moves through it.
Why Pilots Care
Proper function ensures adequate airflow for engine operation and cooling, preventing overheating or power loss.
Intuition Check
An air scoop is not just any hole in the airplane. It is a shaped inlet meant to catch and guide airflow for a specific purpose.
Example Sentence 1
During preflight, the pilot checked the air scoop on the cowling for nests, leaves, or other debris that could block airflow to the engine.
Example Sentence 2
At higher speeds, the air scoop increases the volume of cooling air reaching the cylinders.
