ORS9 – CAA Decision No. 18: Decision amending Guidance Material (GM) for UK Reg (EU) No 923/2012 Article 2 and the Annex
This new guidance material (GM) represents the first in a series of rulemaking activities whose ultimate purpose is to ensure that the UK’s ruleset is fit for purpose. This activity will analyse and combine the content of the Standardised European Rules of the Air (SERA) with the Rules of the Air Regulations 2015 to create a consolidated UK Rules of the Air (ROTA) Regulations.
This first step amends aspects of the retained GM to account for changes to the source International Civil Aviation Organisation (ICAO) Standards and Recommended Practices (SARPs) and Procedures for Air Navigation Services (PANS) and to reflect extant UK operational practises. Moreover, it supports amendments made to UK Reg (EU) No 923/2012 and its annex by the Aviation Safety and Air Traffic Management (Amendment) Regulations 2022.

ORS9 – CAA Decision No. 17: Decision amending Guidance Material (GM) for UK Reg (EU) 2017/373 Annex IV Part-ATS
This new guidance material (GM) represents the first in a series of rulemaking activities whose purpose is to complete the harmonisation of air traffic management (ATM) and air navigation services (ANS) safety regulation under the umbrella of UK Reg (EU) 2018/1139 (“the UK Basic Regulation”), moving away from the current regulatory framework under the Air Navigation Order.
This activity will see the development of UK Reg (EU) 2017/373 “the ATM/ANS Implementing Rule (IR)” through the adoption into Annex IV (Part-ATS) of requirements that are already implemented in the UK through Civil Aviation Publications (CAPs); in particular the Manual of Air Traffic Services (MATS) Part 1 (CAP 493) and the Flight Information Service Officer (FISO) Manual (CAP 797).
Whilst the terms contained in this GM are not yet utilised within the acceptable means of compliance (AMC) to Annex IV (Part-ATS), this will be addressed in subsequent phases of the harmonising rulemaking activity. Importantly, the terms defined within this GM are sourced from International Civil Aviation Organisation (ICAO) Standards and Recommended Practices (SARPs) and Procedures for Air Navigation Services (PANS) and have already largely been implemented in the UK through CAP 1430 the UK ATM Vocabulary.
