India's Aircraft Radio Altimeter Upgrade Amidst 5G Expansion

Abhishek Nayar

08 Jan 2024

As the global rollout of 5G technology continues at an unprecedented pace, the Directorate General of Civil Aviation (DGCA) in India has issued a directive mandating airlines to upgrade their aircraft's radio altimeters (RAs).

This move comes in response to potential interference concerns between 5G telecommunications signals and existing aviation equipment. The decision was prompted by a series of regulatory actions and collaborative efforts between aviation authorities, telecom operators, and aircraft manufacturers.

Background

In November 2022, the Department of Telecommunications (DoT) directed major Indian telecom operators, including Bharti Airtel, Reliance Jio, and Vodafone Idea, to avoid deploying 5G base stations in the 3,300-3,670MHz frequency range (C-band) within specified proximity to airports. These restrictions aimed to prevent interference with airplane RAs and were applicable within zones extending 2,100 meters from both ends of a runway and 910 meters from the runway's centerline.

Temporary Restrictions and Aircraft Manufacturers' Response

To address the potential interference, the DoT imposed temporary restrictions on 5G base stations within a 540-meter perimeter of the specified zones, limiting their power output in the C-band to 58 decibel milliwatts (dBm). This measure was designed to remain in place until all aircraft operating in India were equipped with upgraded RAs.

In December 2022, the DGCA issued a directive instructing airlines to collaborate with aircraft and RA manufacturers for necessary replacements. Boeing and Airbus, two major aircraft manufacturers, communicated their timelines for retrofitting aircraft with upgraded RAs. Boeing aimed to complete the retrofitting of approximately 4,500 operational planes in the United States by March 2024, while Airbus indicated a retrofitting plan for its A320 family planes operating in India with upgraded RAs from Thales, a French electronics company.

Implications for the Indian Aviation Industry

The retrofitting process carries significant implications for the Indian commercial aviation sector, with Air India, for instance, comprising a fleet of 39% 787s and 777s. However, airlines have reassured us that the RA replacement is an overnight process that will not disrupt regular flight schedules. As of August 1, 2023, India's total commercial aircraft count stood at 647, with Airbus and Boeing constituting 68% and 22% of this total, respectively.

Financial Burden on Airlines

The financial burden of the RA upgrade falls squarely on the shoulders of the airlines. While the exact cost remains uncertain, the aviation industry is anticipated to face substantial expenses. The DGCA's decision was a result of extensive discussions with Indian carriers, driven by the DoT's insistence on a clear timeline for RA replacements.

Global Concerns and Varied Perspectives

The urgency of this issue is underscored by the U.S. Federal Aviation Administration reporting over 420 instances of anomalies in radio altimeters in areas with deployed 5G C-band as of January 2023. In nearly 100 cases, the possibility of interference from 5G emissions could not be ruled out. However, telecom industry executives in India emphasize differences between the U.S. and India, particularly a perceived 500 MHz frequency gap that they argue should allow safe aviation operations without interference.

Debates and Advocacy

The Cellular Operators Association of India has advocated for controlled flight simulations to verify that 5G signals do not disrupt air traffic control. The ongoing debate and subsequent actions reflect the complex interplay between advancing telecommunications technology and aviation safety, highlighting the need for careful coordination between sectors to ensure progress and safety in the skies.

Conclusion

India's directive to upgrade aircraft RAs in response to potential 5G interference represents a proactive approach to maintaining aviation safety amidst technological advancements. The collaboration between aviation and telecommunication sectors, along with the commitment of aircraft manufacturers, underscores the importance of regulatory measures to address emerging challenges in a rapidly evolving technological landscape. As the upgrade process unfolds, stakeholders must continue to navigate the complex interdependencies between telecommunications and aviation to ensure the skies remain safe and secure.
