What must foreign aircraft obtain before operating at a USAF airfield?

• A. Temporary Landing Permit
• B. Aircraft Landing Authorization Number
• C. Flight Clearance Document
• D. Aircraft License to Land

Answer: (B)

Foreign aircraft cannot land at a USAF airfield without a formal, base-approved permission known as the Aircraft Landing Authorization Number. This authorization is issued through the base’s airfield operations or the DoD foreign clearance process and ties the landing to a coordinated plan that has been vetted for security, safety, and liaison with base traffic management. It ensures the aircrew, aircraft, and arrival time are all screened and aligned with the base’s procedures; without it, landing clearance would not be granted.

Other terms like a temporary landing permit, a general flight clearance document, or an aircraft license to land do not reflect the specific base-level authorization required for foreign aircraft to operate on USAF fields.
