Definition
The FAA advisory circular (AC 150/5300-13) that establishes the standards and recommendations for the geometric layout and dimensions of airports, including runways, taxiways, safety areas, object clearances, and protection zones. It defines the criteria used to plan, build, and certify civilian airports in the United States.
Plain English
It is the FAA's official rulebook for how an airport must be laid out — how wide runways are, how far things must be from the runway edge, and how much clear space must surround it.
Context Anchor
Seen in runway safety area discussions, airport diagrams, preflight planning, and explanations of why certain airport areas must stay clear.
Derivation
Airport combines “air” with “port,” meaning a place where aircraft arrive and depart. Design means a planned arrangement. Together, the term points to the planned arrangement of the airport, not just how it looks.
Why Pilots Care
Correct airport design directly reduces the chance of runway excursions by providing required clear areas for aircraft to stop or maneuver safely.
Grounding Statement
An airport is designed so an aircraft has a predictable path to follow and extra protected space if things do not go exactly as planned.
Intuition Check
Do not read “airport design” as decoration or architecture. In this context, it means the safety-focused layout and construction of the airport operating areas.
Example Sentence 1
The width of the runway safety area is determined by the FAA's Airport Design standards.
Example Sentence 2
Understanding airport design helps a pilot anticipate how much overrun distance is available during a rejected takeoff.
