EASA SIB 2010-21R3: WITHDRAWNÂ - RECOMMENDATIONS NOT NEEDED ANYMORE

What to do

Operators should ensure that any use of EGNOS for vertical navigation is supported by specific installation certification and operational approval from the competent authority. Pilots and operators are encouraged to report any occurrences or issues related to EGNOS use using Form 44 and send completed reports to report@easa.europa.eu. For further information or assistance, stakeholders should contact the designated EASA and EGNOS helpdesk email addresses provided in the bulletin.

Summary

EASA Safety Information Bulletin 2010-21R3 is an informational bulletin regarding the activation and operational status of the European Geostationary Navigation Overlay Service (EGNOS), a Satellite-Based Augmentation System (SBAS) for GPS. It applies to all aircraft equipped with EGNOS-enabled GPS receivers and provides updates on the certification and use of EGNOS for aviation navigation, including vertical guidance capabilities. The bulletin clarifies that EGNOS is now fully operational for safety of life services, including vertical navigation, following the lifting of previous restrictions.

What changed

This revision of EASA SIB 2010-21 updates hyperlinks to new web locations for relevant documents and reports, and provides the latest status of EASA Acceptable Means of Compliance AMC 20-28. It confirms the lifting of restrictions on the use of EGNOS for vertical navigation and guidance, allowing full use of EGNOS-enabled receivers for all approved applications, including APV SBAS approaches down to LPV or LNAV/VNAV minima.

Why it matters

This bulletin informs aviation professionals that EGNOS is now fully certified and operational for all navigation applications, including vertical guidance, which enhances navigation accuracy and safety. Operators and pilots can use EGNOS-enabled GPS receivers without restrictions previously imposed, improving approach capabilities and operational efficiency. Compliance teams and maintenance organizations must be aware of certification and operational approval requirements for vertical guidance use to ensure regulatory compliance.
