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

: Providing design rules for the five segments of an instrument approach: arrival, initial, intermediate, final, and missed approach. Icao Doc 8168 Vol 2

: 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,

Volume II is divided into parts that address different navigation technologies and phases of flight: Key Technical Components Volume II is divided into

: Defining the minimum vertical separation (MOC) required between an aircraft and any terrain or man-made obstacles.

: Designing for traditional ground-based aids like VOR, NDB, and ILS.

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:
