Icao Doc 8168 Vol 2 May 2026

, 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

Volume II is divided into parts that address different navigation technologies and phases of flight: Icao Doc 8168 Vol 2

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

: Protecting the transition from instrument flight to visual landing. Latest Updates

: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles.

: Grouping aircraft by stall speed to determine specific obstacle clearance altitudes (OCA/H) for each type. Key Technical Components
