, 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
: Providing design rules for the five segments of an instrument approach: arrival, initial, intermediate, final, and missed approach. : Protecting the transition from instrument flight to
: Modern criteria for GPS and area navigation, including RNP (Required Navigation Performance) and Baro-VNAV. Core Purpose and Scope : Providing design rules
: Grouping aircraft by stall speed to determine specific obstacle clearance altitudes (OCA/H) for each type. Key Technical Components
: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles.
: Designing for traditional ground-based aids like VOR, NDB, and ILS.
