Icao Doc 8168 Vol 2 -
: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles.
: Protecting the transition from instrument flight to visual landing. Latest Updates
, 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
: Designing for traditional ground-based aids like VOR, NDB, and ILS.
Volume II is divided into parts that address different navigation technologies and phases of flight: : Specific rules for straight and turning departures,
: Defining the minimum vertical separation (MOC) required between an aircraft and any terrain or man-made obstacles.
: Providing design rules for the five segments of an instrument approach: arrival, initial, intermediate, final, and missed approach. While Volume I is designed for flight crews,
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:
