Icao Doc 8168 Volume 3 Jun 2026

The guidelines in ICAO Doc 8168 Volume 3 are essential for ensuring the safety and efficiency of air navigation services. By following these guidelines, air navigation service providers, flight procedure designers, and aircraft operators can ensure that instrument procedures are designed and implemented in a way that minimizes the risk of accidents and optimizes air traffic flow.

Consider a standard hold over a fix at 10,000 feet. A pilot might think, "I’ll just fly a 1-minute leg." But according to , if the temperature is -30°C, the true airspeed (TAS) increases, thus the aircraft covers more ground distance. The designer must expand the protected area accordingly. Failure to do so results in the aircraft flying into a mountain 5 miles away that was "outside" the standard template. icao doc 8168 volume 3
