The Connectivity Issue: 5G Connectivity, UAS Traffic Management, ACARS-Over-IP, LEO Satellites for In-Flight Connectivity, and More

This issue of Avionics International is centered around connectivity. In the first article, we take a look at concerns about interference with aircraft radio altimeters, prompted by recent expansions of 5G networks by U.S. telecommunications companies. These altimeters can be impacted by 5G signals, especially during critical phases of flight like landing and take-off. While there have been efforts to mitigate the interference by adjusting 5G deployments around airports, aircraft operators have been urged to retrofit or upgrade their systems by a set deadline to avoid operational disruptions, as the potential for interference poses risks to flight safety.

In the second featured article in this issue, writer Pat Host explores the need for a more efficient traffic management system for UAS (uncrewed aircraft systems). UAS service providers are urging the FAA to set a regulatory framework for the safe integration of small UAS into the airspace. As the number of UAS operations is expected to surge, current air traffic control methods are deemed inadequate to manage the growth, emphasizing the need for a more efficient traffic management system and the acceleration of the integration process.

In this issue of Avionics International, we also examine technological advancements in aircraft connectivity and the associated cybersecurity challenges. To safeguard against these risks, regulatory bodies like the FAA and EASA mandate Aircraft Network Security Programs (ANSPs). Writer Mark Robins explains that older aircraft, which were not originally designed with such advanced connectivity in mind, can be retrofitted to comply with modern security standards.

Another feature article, contributed by Aaron Karp, covers the aviation industry’s transition to ACARS over IP. This solution allows aircraft to transmit large volumes of data using internet protocols, while still ensuring safety-critical data uses traditional communication channels. Implementing ACARS over IP enhances real-time flight data accessibility and data sharing in the aviation ecosystem, enabling airlines to boost operational efficiency, mitigate risks, and potentially achieve significant operational savings.
