EASA SIB 2021-12R1
Use of Aeronautical Terminal Information Service by Air Traffic Services Units to Promulgate Information on Runway Surface Conditions — Global Reporting Format
Summary
EASA Safety Information Bulletin 2021-12R1 is an advisory document addressing the use of Aeronautical Terminal Information Service (ATIS) by Air Traffic Services units to disseminate information on runway surface conditions using the Global Reporting Format (GRF). It applies to national competent authorities, air navigation service providers, aerodrome operators, and aircraft operators. The bulletin clarifies procedures for communicating runway surface conditions to flight crews to enhance safety during take-off and landing on wet or contaminated runways.
What Changed
This revision updates the previous SIB 2021-12 by clarifying the use of voice-ATIS and digital ATIS in the context of GRF implementation, emphasizing that braking action information should not be included in ATIS messages to avoid conflicts with GRF principles. It also highlights the need for ATS units to maintain concise, accurate, and up-to-date ATIS messages and addresses inconsistencies between ICAO Annex 11 provisions and GRF requirements.
Why It Matters
The bulletin is important for aviation professionals as it ensures consistent and accurate communication of runway surface conditions, which is critical for safe aircraft performance calculations and preventing runway excursions. It guides ATS units and aerodrome operators on harmonizing procedures and managing information flow effectively, thereby supporting operational safety and regulatory compliance.
What To Do
Air navigation service providers should review and coordinate their procedures with aerodrome operators to ensure consistent dissemination of runway surface condition information via voice-ATIS and digital ATIS, and provide necessary training to personnel. National competent authorities should consider these recommendations during safety oversight activities. The GRF implementation date in the EU is 12 August 2021, and stakeholders should ensure readiness by this date.
