Force-System Resultants and Equilibrium
Published in Richard C. Dorf, The Engineering Handbook, 2018
Airports range from small unmarked grass strips to major facilities requiring many thousands of acres and billions of dollars. Strictly speaking, an airport consists of an airfield (or “airside”) and terminal (or “landside”). Airports are designed to accommodate specified traffic loads carried by aircraft up to a “design aircraft,” which is the most demanding aircraft to be accommodated. The design aircraft might determine such features as runway lengths, pavement strengths, or terminal gate dimensions at an airport. Detailed guidelines for most aspects of airport design (e.g., runway lengths and other airfield dimensions, pavement characteristics, drainage requirements, allowable noise and other environmental impacts, allowable obstruction heights, lighting, markings, and signing) are specified by the U.S. Federal Aviation Administration (FAA) in a series of circulars.
Why can’t the PCN index be uniquely defined?

Airports are vital transportation substructures, as they serve a key role in the transportation of people and goods for regional, national and international commerce. Among the most critical facilities of an airport are the airfield pavements. The main objective of the airfield pavements is to provide an adequate load-carrying capacity, necessary for the safe operation of aircrafts utilizing the airport. With this in mind, the existence of a valid and globally utilized system for reporting airfield pavement bearing capacity has long been the subject of research and investigation activities. For this reason it has always been critical for airport authorities to have a simple and suitable classification and reporting system which will facilitate the management of airfield pavements.

The International Civil Aviation Organization (ICAO) and the FAA also develop their respective Aerodrome Reference Codes (or FAA Airport Reference Codes) to indicate the design standards of the airfields’ capabilities, which could also be incorporated into standards and recommended practices for commercial spaceports. Furthermore, as commercial spaceports become truly commercial, there will be a need for more transparency in the business aspects of the spaceport operations such as fees and charges spaceports impose on their customers.

An airfield runway is bordered by runway safety areas to promote aircraft safety during an aircraft accident or incident. The runway safety area bordering the runway ends is referred to as the runway end safety area. The size of the runway safety area is based on early studies conducted by the Federal Aviation Administration (FAA). The FAA study by David (1990) investigated commercial aircraft accidents/incidents between 1978 and 1987. Two-hundred and forty-six accidents/incidents were considered relevant to the study. Approximately 13% of these accidents/incidents were overruns. Twice as many overruns occur during landing than during takeoff. In a more recent study, Hall et al. (2008) reviewed accident/incident data between 1982 and 2006 considering geographic regions with similar accident/incident rates as the US: North America, Western Europe, Oceania, and limited Asian countries. During this time period, 459 relevant overrun accident/incident events occurred. Of these, 60% occurred during landing, 20% during takeoff, and 20% as undershoots. In order to minimise the negative impact of overrun events, the FAA requires a runway safety area (RSA) extending a minimum of 305 m (1000 ft) beyond the runway design length (FAA 2012).
