Which combination produces the Airport Reference Code (ARC)?

The Airport Reference Code (ARC) is a standardized classification that combines two critical components: the Aircraft Approach Category (AAC) and the Aircraft Design Group (ADG). The AAC considers the approach speed of aircraft, which helps in determining suitable approaches and types of navigational aids for the airport infrastructure. Meanwhile, the ADG evaluates the physical dimensions and characteristics of aircraft, such as wingspan and tail height, which inform runway widths, lengths, and the necessary safety areas surrounding runways.

This combination of the AAC and ADG enables the classification of the airport's operational capabilities and helps guide design standards, as well as operational criteria necessary for different types of aircraft. Understanding this classification is vital for airport planning, design, and operations, ensuring that facilities can accommodate the types of aircraft that will be using the airport.
