CAP 797 Flight Information Service Officer Manual

Supplementary Instruction (SI) 2020/04 to CAP 797 Flight Information Service Officer (FISO) Manual Edition 3 was published on 14 July 2020, effective 10 September 2020.

ICAO has introduced measures to align the performance-based navigation (PBN) procedure approach chart identification with the designation of the navigation specification, transitioning from the RNAV(GNSS) Runway XX naming convention, to RNP Runway XX. 

The UK’s plan to adopt this naming convention is described within AIC Y 140/2019. The purpose of this SI to the FISO Manual (CAP 797) is to introduce the revised nomenclature for PBN instrument approach procedures.
