In the Asia-Pacific region, airlines are extending their aircraft's operational lifespans while meeting new regulatory requirements for interference-tolerant radio altimeters. This combination has led to increased demand for avionics retrofits, according to Thales, a major provider of aircraft electronics.
Thales has announced ongoing contracts to retrofit its Long-Range Radio Altimeter (LRRA), which is immune to 5G interference, on a significant number of both in-service and new aircraft. The company's general manager for APAC, Thomas Mouveaux, highlighted the importance of such upgrades, noting that aircraft can remain operational for decades, whereas the communications environment can change rapidly.
Operational and Regulatory Challenges
Airlines in the region operate diverse aircraft configurations across various regulatory and spectrum environments, resulting in a range of requirements for avionics upgrades. Thales provides exchange units that enable rapid replacement of radio altimeters, minimizing aircraft downtime. During the process, removed units are upgraded and tested at Thales facilities, including one in Singapore.
Broader Avionics Modernization
Beyond interference-tolerance, airlines are seeking newer avionics functionalities to enhance safety and efficiency—such as advanced flight management systems and upgraded Traffic Alert and Collision Avoidance Systems. However, access to spare components remains a challenge due to strict safety, reliability, and certification standards.
"The response has been to build more resilience into the supply chain, securing manufacturing capacity, ensuring a global talent network and maintaining strategic inventory where appropriate," said Mouveaux.
This approach aims to address the key issues of component availability and repair capacity, ensuring that airlines can meet regulatory demands without compromising operational reliability.
