Aircraft go blank over Mideast

NEW DELHI: Given the rising reports of Global Navigation Satellite System (GNSS) interference in Middle Eastern airspace in recent times, the Director General of Civil Aviation (DGCA) has issued an advisory circular addressing the issue. The circular pointed to the growing threats posed by GNSS jamming and spoofing, identifying specific geographical areas where these incidents have been observed and outlining their potential impact on both aircraft and groundbased systems.

“This circular, released during a period of heightened uncertainty within the aviation industry due to new threats and reports of GNSS jamming and spoofing, offers much-needed guidance and clarity. It presents a practical roadmap and action plan to effectively address the threat of GNSS interference in airspace,” stated DGCA officials.

In response to recent incidents where the navigation systems of civilian aircraft were reportedly spoofed while flying over parts of the Middle East, the DGCA established an internal committee on October 4, 2023. Since its formation, the committee has assessed the situation, raised awareness among operators, and engaged in discussions with leading global experts on the subject. The circular based on the committee's recommendations, incorporates best practices, recent developments, and guidance from the International Civil Aviation Organisation (ICAO) to counter the emerging threat.

Applicable to all aircraft operators, air navigation service providers (ANSPs), and the Airport Authority of India, the circular delineates the roles and responsibilities of each stakeholder in monitoring and mitigating the threat in a coordinated manner.
