FOMAX Enhances Data Connectivity for Airbus A320 and A330 Aircraft
FOMAX by Collins Aerospace and Airbus improves data exchange and predictive maintenance for A320 and A330 aircraft families.
This article is based on official product information and press releases from Collins Aerospace (RTX) and Airbus.
In the evolving landscape of commercial aviation, data connectivity has become as critical as aerodynamics. At the center of this digital shift for Airbus aircraft is the Flight Operations and Maintenance Exchanger, known as FOMAX. Developed through a strategic Partnerships between Collins Aerospace (an RTX business) and Airbus, this system serves as the central nervous system for data exchange on A320 and A330 aircraft families.
According to product specifications released by Collins Aerospace, FOMAX is designed to capture vast amounts of aircraft performance and MRO data, securely transmitting it to ground operations. The system is supported by “Ground FOMAX Managed Services,” a cloud-based infrastructure that ensures the secure flow of information between the aircraft and airline back-office systems.
This technology represents a significant move toward the “connected aircraft,” enabling predictive Maintenance, real-time pilot applications, and operational efficiency gains that legacy systems could not support.
FOMAX functions as both an Aircraft Interface Device (AID) and a Secure Server Router (SSR). According to technical documentation summarized in industry reports, the unit connects the aircraft’s Avionics to open-world ground networks without compromising the safety of critical flight systems.
The system’s capabilities include:
Collins Aerospace notes that the system also facilitates “ACARS over IP,” upgrading traditional text-based messaging systems to faster internet-based protocols, which can reduce communication costs for operators.
While the hardware resides on the aircraft, the ecosystem relies heavily on “Ground FOMAX Managed Services.” Part of the Collins GlobalConnect suite, this service layer acts as the bridge between the flying hardware and the airline’s IT infrastructure.
Official descriptions of the service highlight its role in security and routing. The system utilizes Virtual Private Networks (VPNs) to create encrypted tunnels for data transfer. It also employs intelligent data routing, automatically selecting the most cost-effective transmission path, prioritizing 4G/LTE on the ground over more expensive satellite links in the air. “Ground FOMAX Managed Services supports all FOMAX equipped A320 and A330 families of aircraft… [ensuring] connectivity to other avionics already in place.”

Furthermore, the service manages security through “whitelisting” and digital certificates, ensuring that only authorized applications and users can interface with the aircraft. This allows Airlines to remotely update software and navigation databases, eliminating the need for mechanics to manually upload data via laptops.
The FOMAX system is tailored specifically for Airbus single-aisle and wide-body families. According to Airbus production standards, the hardware is now “Basic Linefit” for new aircraft.
All new A320 (including neo) and A330 (including neo) aircraft are delivered with FOMAX hardware pre-installed. Industry data indicates this became standard on production lines starting approximately around 2018/2019.
For older fleets, Collins Aerospace and Airbus provide retrofit paths via Airbus Service Bulletins (SB). These upgrades typically fall under ATA Chapter 46 (Information Systems). Operators can install the hardware to bring older airframes into the modern digital ecosystem, ensuring fleet-wide data uniformity.
The adoption of FOMAX has led to tangible operational changes for major carriers. In December 2023, easyJet announced it had become the world’s largest A320 operator to deploy the GlobalConnect service, activating it on over 330 aircraft.
In their announcement, easyJet highlighted the environmental and efficiency benefits of the system. By utilizing FOMAX for digital data retrieval, the airline was able to remove heavy “Quick Access Recorders” from their aircraft.
“The airline projects that removing older, heavy ‘Quick Access Recorders’… will save 500 tonnes of carbon annually.”

Additionally, the system feeds into predictive maintenance platforms. By analyzing data trends, airlines can predict part failures before they occur, reducing “Aircraft on Ground” (AOG) delays and improving schedule reliability.
The widespread integration of FOMAX signals a definitive end to the era of “sneaker-net” in aviation maintenance, where mechanics physically walked data disks off aircraft. By standardizing this hardware on the A320 and A330 lines, Airbus has effectively forced a modernization of airline IT operations.
However, the reliance on “Ground FOMAX Managed Services” also illustrates the increasing shift toward Software-as-a-Service (SaaS) models in aviation. Airlines are no longer just buying parts; they are subscribing to data ecosystems. While this improves efficiency, it also binds operators more tightly to OEM-managed infrastructure for the lifespan of the airframe.
