As the deadline for the implementation of the 5G network approaches, US airlines are bracing themselves for potential flight delays and disruptions. The introduction of 5G technology has raised concerns regarding interference with radio altimeters, which could impact the safe operation of aircraft. This article explores the possible issues that airlines may face due to the deployment of 5G and its implications for air travel in the US.
The Clash between 5G and Airlines: The conflict between 5G technology and the aviation industry revolves around the use of a frequency band previously allocated for satellite TV. The Federal Communications Commission (FCC) auctioned off the rights to this band for 5G deployment to mobile carriers, including Verizon and AT&T. However, the Federal Aviation Administration (FAA) raised concerns about potential interference with radio altimeters, which are crucial for determining altitude during final approach and landing.
Delays and Compromises: Although concerns about interference were raised as early as 2015, the FAA did not communicate them directly to the FCC until later. This delayed confrontation led to a last-minute agreement between the wireless providers and the aviation industry in early 2020. The agreement imposed temporary restrictions on the 5G C-band spectrum around 50 major airports and mandated airlines to update their older aircraft’s radio altimeters by July 1, 2023.
Implications for Airlines and Travelers: As the deadline approaches, airlines are working diligently to retrofit their aircraft with updated radio altimeters. American Airlines, Southwest Airlines, and Frontier Airlines have completed the retrofitting process and do not anticipate any issues. However, airlines such as JetBlue and Delta have acknowledged that only a portion of their fleet has been updated, with Delta reporting that nearly 190 of its more than 900 aircraft are still awaiting retrofit.
This situation could potentially lead to flight delays and cancellations, particularly for aircraft that have not undergone retrofitting. While domestic airlines are taking measures to mitigate the impact by using compliant aircraft for international flights and non-compliant aircraft for domestic flights to less weather-vulnerable airports, challenges remain. Supply chain problems have also been reported, making it difficult to acquire the necessary equipment for retrofitting.
The impending deployment of the 5G network poses challenges for US airlines as they work towards ensuring the compatibility of their aircraft with the new technology. While many airlines have made progress in retrofitting their planes, there is still a considerable number awaiting updates, especially among foreign carriers. The aviation industry, along with wireless providers, continues to address the concerns raised by potential interference to ensure safe and efficient air travel. Travelers should stay informed about any potential disruptions and remain patient as airlines navigate this complex transition period.
