Vol 2 — Icao Doc 8168

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

: Establishing parameters for turn areas, including wind spirals and bank angles, to ensure aircraft stay within protected airspace. Icao Doc 8168 Vol 2

: Grouping aircraft by stall speed to determine specific obstacle clearance altitudes (OCA/H) for each type. Key Technical Components Volume II is divided into parts that address

: Protecting the transition from instrument flight to visual landing. Latest Updates including wind spirals and bank angles

: Modern criteria for GPS and area navigation, including RNP (Required Navigation Performance) and Baro-VNAV.

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

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