Icao Doc 8168 Vol 2 -

, 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
