It is the invisible architecture that allows air traffic control and pilots to operate in a cohesive manner, regardless of nationality or airspace complexity. This section is crucial for planners who design Standard Instrument Departures (SIDs), ensuring that the initial climb phase is both efficient and inherently safe, mitigating the risk of controlled flight into terrain.
This rigorous definition is what allows an aircraft to descend safely toward the runway in low visibility conditions. ICAO Doc 8168, formally titled Document 8168 — Aircraft Operations, is the global standardisation beacon for one of the most critical phases of aviation: the flight itself.

It dictates the dimensions of the protected airspace, known as the "Inner Horizontal Plane" and "Obstacle Identification Surfaces," ensuring that any obstacle protruding into the airspace is accounted for in the signal geometry. As aviation technology evolves, so does the application of ICAO Doc 8168.
