The Directorate General of Civil Aviation (DGCA) has issued a comprehensive advisory to all Indian airlines and the Airports Authority of India (AAI) in response to increasing concerns over the spoofing of Global Navigation Satellite Systems (GNSS) in the Middle East airspace. Reports have emerged that civilian aircraft may be at risk of flying blind due to the manipulation of navigation systems, posing a significant safety hazard.
The circular underscores the emerging threats of GNSS jamming and spoofing, pinpointing specific geographical areas where such interference has been observed. The DGCA has taken proactive measures to address this issue, forming an internal committee on October 4 to assess the situation, sensitize operators, and engage with international experts on the matter.
Key Points from the Circular:
- Mitigation Measures: The circular outlines comprehensive mitigation measures and action plans for aircraft operators, pilots, Air Navigation Service Providers (ANSP), and air traffic controllers. This includes the development of contingency procedures in collaboration with equipment manufacturers and assessing operational risk through safety risk assessments.
- Committee Recommendations: Recommendations provided in the circular are based on insights from the committee, considering best practices, the latest developments, and guidance from the International Civil Aviation Organization (ICAO).
- Threat Monitoring Network: The DGCA emphasizes the need to establish a threat monitoring and analysis network by ANSP in close coordination with the DGCA. This network aims to monitor and analyze reports of GNSS interference, providing valuable insights and data for preventive and reactive measures.
- Global Aviation Uncertainties: Highlighting the challenges faced by the aviation industry, the circular acknowledges uncertainties arising from new threats, including GNSS jamming and spoofing.
- Immediate Threat Response: The circular serves as a practical roadmap and action plan to effectively deal with the threat of GNSS interference in airspace. It aims to provide much-needed guidance and clarity to all stakeholders involved in ensuring aviation safety.
Aviation experts have raised concerns about the increasing incidents of GNSS interference, with one notable instance in late September where multiple commercial flights near Iran deviated off-course due to navigation system disruptions.
The DGCA’s advisory comes as a timely response to safeguard the integrity of navigation systems and enhance aviation safety in the face of evolving threats.
