: Defining the minimum vertical separation (MOC) required between an aircraft and any terrain or man-made obstacles.
: Modern criteria for GPS and area navigation, including RNP (Required Navigation Performance) and Baro-VNAV. Icao Doc 8168 Vol 2
: Grouping aircraft by stall speed to determine specific obstacle clearance altitudes (OCA/H) for each type. Key Technical Components : Defining the minimum vertical separation (MOC) required
, 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 Key Technical Components , formally titled "Construction of
Volume II is divided into parts that address different navigation technologies and phases of flight:
: Specific rules for straight and turning departures, often requiring minimum climb gradients (typically 3.3%) to clear obstacles.
