: Modern criteria for GPS and area navigation, including RNP (Required Navigation Performance) and Baro-VNAV.

, 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

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: : Modern criteria for GPS and area navigation,

: Protecting the transition from instrument flight to visual landing. Latest Updates Core Purpose and Scope The primary goal of

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

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