Description
ICAO Circular 324 – Guidelines for Lateral Separation of Arriving and Departing Aircraft on Published Adjacent Instrument Flight Procedures.
The purpose of this circular is to apprise States of the ICAO guidelines and supporting material for the implementation of separation minima developed for arriving and departing aircraft on published adjacent instrument flight procedures (IFPs). This material supports provisions included in the Procedures for Air Navigation Services — Air Traffic Management (PANS-ATM, Doc 4444), Chapter 5, 5.4.1.2.1.4 (see Chapter 2 of this circular). It provides for two separation minima between certain performance-based navigation-capable aircraft utilizing IFPs and lateral separation between aircraft on IFPs using protected areas.
