Volume II is divided into parts that address different navigation technologies and phases of flight:
: Providing design rules for the five segments of an instrument approach: arrival, initial, intermediate, final, and missed approach. Icao Doc 8168 Vol 2
: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles. Volume II is divided into parts that address
: Grouping aircraft by stall speed to determine specific obstacle clearance altitudes (OCA/H) for each type. Key Technical Components Key Technical Components : Establishing parameters for turn
: Establishing parameters for turn areas, including wind spirals and bank angles, to ensure aircraft stay within protected airspace.
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:
, 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.
