What must all 14 CFR Part 139 airports report?

All 14 CFR Part 139 airports are required to report declared distances for each runway. Declared distances are critical measurements used in assessing an airport's ability to handle aircraft operations safely. These measurements include the length of the takeoff run available, the length of the takeoff distance available, the length of the landing distance available, and usable runway lengths which account for any obstructions.

Proper reporting of declared distances ensures that pilots and airlines have accurate information to make safe operational decisions, especially regarding takeoff and landing performance calculations. This information is crucial for maintaining compliance with safety standards and operational guidelines established by the FAA.

Other options, while relevant in various contexts, do not have the same regulatory requirement for all Part 139 airports as declared distances. Noise complaint statistics, passenger emergency evacuation statistics, and annual passenger traffic summaries may be pertinent for certain operational aspects or specific airport management practices but are not universally mandated reports under the Part 139 regulations.
