The four-letter scheme used in Doc 7910 is the foundation of the ICAO system for identifying airports. This system has a regional structure that provides immediate context. For example, airports in the contiguous United States often have codes beginning with "K" (e.g., KLAX for Los Angeles), while airports in the United Kingdom use the "EG" prefix (e.g., EGLL for London Heathrow). This structure is not just for convenience; it is a critical safety feature. Air traffic control (ATC), pilots, and airline operations staff rely on these codes to avoid ambiguity. When a flight plan lists a destination as "KJFK," there is no doubt that it means the John F. Kennedy International Airport in New York, a clarity that is impossible with colloquial names alone. The stability of these indicators is paramount, and changes are made only after rigorous consideration to prevent confusion in international airspace.
