Which of the following describes a WCHS passenger?

• A. Can walk by themselves inside the plane but cannot walk up and down the stairs and requires a wheelchair to move inside the airport
• B. A passenger who is completely immobile and requires assistance at all times
• C. Can walk inside the plane and up the stairs but needs assistance on the ground
• D. Needs wheelchair only when boarding

Answer: (A)

A WCHS passenger is someone who needs a wheelchair to move around in the airport but can walk by themselves once aboard the aircraft. They can move unaided inside the plane, but cannot walk up and down stairs and require the wheelchair to navigate the airport environment.

This matches the described option: the passenger can walk inside the plane, cannot use stairs, and relies on a wheelchair to move around in the airport. The other descriptions imply full immobility, or mobility on the ground without a wheelchair, or wheelchair use only at boarding, which don’t align with the stated pattern of needing a wheelchair in the airport but not inside the aircraft.
