Where are the air stairs located on the aircraft?

The air stairs are designed to facilitate boarding and deplaning passengers directly from the aircraft. They are specifically integrated into the door structure of the aircraft, allowing for a safe and efficient means of entering and exiting. This design means that when the aircraft is parked at an airport or location not serviced by a jet bridge, the air stairs can be deployed for passenger use.

In contrast, options mentioning locations like the front galley, cargo door, or over the wing exit do not accurately represent the primary function and positioning of air stairs. The front galley is primarily for in-flight service and does not accommodate passenger access. Cargo doors are intended for loading and unloading baggage and cargo, and wing exits are typically used for emergency evacuations or specific boarding procedures on certain aircraft models and do not feature detachable air stairs.
