: Establishing parameters for turn areas, including wind spirals and bank angles, to ensure aircraft stay within protected airspace.

, formally titled "Construction of Visual and Instrument Flight Procedures," is the essential technical manual for procedure design specialists. While Volume I is designed for flight crews, Volume II provides the complex mathematical criteria and obstacle clearance requirements needed to build safe, regular instrument flight operations worldwide. Core Purpose and Scope Icao Doc 8168 Vol 2

Procedures for Air Navigation Services (PANS) - Aircraft Operations : Establishing parameters for turn areas, including wind

: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles. Core Purpose and Scope Procedures for Air Navigation

: Providing design rules for the five segments of an instrument approach: arrival, initial, intermediate, final, and missed approach.

: Designing for traditional ground-based aids like VOR, NDB, and ILS.

The primary goal of Volume II is to standardize how States, operators, and charting organizations design flight procedures. This uniformity ensures that a pilot flying into any international aerodrome can rely on consistent safety margins, regardless of local terrain. Key areas of focus include:
