EASA SIB 2022-02R3
Global Navigation Satellite System Outage and Alterations Leading to Communication / Navigation / Surveillance Degradation
Summary
EASA Safety Information Bulletin 2022-02R3 is a revised safety information bulletin addressing the increase in jamming and spoofing of Global Navigation Satellite Systems (GNSS) affecting aviation operations. It highlights the impact on navigation, communication, and surveillance systems, particularly in regions near conflict zones and various European and surrounding areas. The bulletin applies to competent authorities, air traffic management providers, air operators, and manufacturers involved in ATM/ANS equipment.
What Changed
This revision updates the previous EASA SIB 2022-02R2 by including newly observed issues related to GNSS jamming and spoofing and refining recommendations for mitigating these effects. It separates recommendations for jamming and spoofing due to their differing characteristics and expands guidance on contingency procedures and monitoring.
Why It Matters
The bulletin is critical for aviation professionals as GNSS interference can degrade or disable key navigation and surveillance systems, increasing workload and safety risks during flight. Operators and air traffic controllers must be prepared to recognize and respond to these disruptions to maintain safe flight operations and airspace management.
What To Do
Competent authorities should establish contingency procedures and maintain non-GNSS navigation aids, issue NOTAMs for affected areas, and coordinate with telecommunications authorities to monitor GNSS interference. ATM/ANS providers must collect and share GNSS degradation information, ensure surveillance resilience, and train controllers on interference scenarios. Air operators should train flight crews to detect and report GNSS anomalies promptly. No specific compliance deadlines are stated.
