It outlines the approach SITAbelieves is essential for ensuring AAM vehicles maintain safety-level communications with aircraft,supporting the continuity of safe and efficient operations. AAM vehicles already outnumber conventional aircraft. While approximately 400,000 traditionalaircraft occupy global airspace (Commercial airliners, general aviation and civil helicopters), thecurrent commercial small drone population has reached 800,000 units. This disparity—a ratioof 2:1—represents only the initial phase of what experts suggest will be a continuing exponentialgrowth in the AAM segment. The Challenge:AAM Communication Infrastructure The implementation of reliable communication systems that satisfy Civil Aviation Authorities suchas the Federal Aviation Administration requires both technical expertise and a comprehensiveunderstanding of aviation's safety-prioritized operational framework. This presents a significantchallenge for most AAM operators who typically originate from commercial innovation sectorsrather than traditional aviation environments. The best way for AAM entities to tackle this would be to seek out guidance from establishedaviation stakeholders who already have the experience and understand the best ways of working tonavigate this highly regulatory environment effectively and efficiently. SITA’s approach:AAM Livestream Concept, a ContemporarySecure Connectivity Solution SITA is exploring a new technological and organizational structure for AAM communications thatwill meet future safety objectives, while preserving the integrity of existing systems. Their mission isto develop secure hyperconnectivity to support the evolving needs of the AAM ecosystem. SITA envisions a future with "AAM Livestream," a customizable service that provides AAM vehicleswith uninterrupted, secure communication capabilities. This service addresses critical operationalscenarios, including drone operations in rural areas with limited connectivity, unmanned passengertransport vehicles in low-altitude urban environments where communication integrity is non-negotiable, and mixed-traffic areas where AAM operates in controlled airspace. “AAM Livestream” is characterized by diverse network infrastructure, distributed data centres,and communication systems typically spread across multiple service providers with intensivedependence on non-protected spectrum connectivity modules. Infrastructure Communications Data Responsible for physicalconnectivity and the availabilityof transmission media. Handles databases, APIs, and analyticsto increase revenue and safety. At SITA we believe safe and secure AAM operations require a comprehensive modelintegrating collective cybersecurity management across all system elements whileguaranteeing complete network availability. Achieving this will also likely involve evolutionarymodifications to global standards and regulatory frameworks. An Evolutionary Connectivity Concept: Advanced Air Mobility vehicles encounter several challenges on getting certification tooperate from Civil Aviation Authorities (CAAs) often causing launch dates to be delayed. SITA'sproposed comprehensive managed service framework ensures technical specifications acrosscommunication systems, data architecture, and infrastructure deployments meet regulatoryand safety requirements. Such structure will foster and streamline the certification process ofoperations and services in the CAA managed environment, giving them complete peace of mindand allowing AAMs to focus on their core business. SITA’s established position within aviation's institutional framework provides optimal capabilitiesfor implementing reliable connectivity solutions, including in geographically isolated operationalenvironments. Our services effectively manage compliance complexities such as those mandatedby CAAs ensuring continuous communication availability for AAM platforms while significantlyreducing operational safety vulnerabilities. We will provide expertise in mitigating unidentified communications risk factors for AAM operators,supporting flight authorization within current regulatory structures while the industry progressestoward fully integrated and Hyperconnected Air Traffic Management. AAM Livestream implements a methodologically flexible framework designed to accommodate theaviation industry's evolving oper
