Icao Doc 8168 Volume 3 ((link))
If you are a professional pilot, you know ICAO Doc 8168. You probably refer to it simply as "PANS-OPS" (Procedures for Air Navigation Services – Aircraft Operations). You have likely spent hours memorizing Volumes I and II—specifically the criteria for departure, arrival, and approach procedures.
Most modern instrument procedure design software (e.g., Airbus ProSky, Navblue, or even open-source tools) has Volume 3 rules hard-coded. When you input "holding pattern at 8,000 ft," the software applies the wind spiral and turn radius formulas from Volume 3 automatically. However, a qualified designer must still verify the output.
The document clarifies that when DME is used for holding legs, the distance should be measured from the DME station, not from the fix. This is a common source of navigational error.
Every time a pilot lines up for an instrument approach, executes a missed approach, or navigates a holding pattern, they are trusting a meticulously designed procedure. But who designs these procedures? And what rulebook do they follow? icao doc 8168 volume 3
The first edition of Volume III was approved in 2018 and became applicable globally on November 8, 2018
Simultaneous Operations on Parallel or Near-Parallel Runways (SOIR)
When a pilot misses an approach, the holding pattern at the missed approach fix is often the last line of defense. Volume 3 dedicates extensive tables to the "Missed Approach Holding" — specifically, how close this hold can be placed to terrain and how long the initial missed approach segment must be before the first turn.
