The rapid advancement of remotely piloted aircraft systems in commercial and research sectors, noting the challenges of integrating these services into non-segregated civilian airspace, including regulatory, security, and technical issues, is discussed in paper [24]. The paper introduces a flexible communication infrastructure manager utilizing software-defined networking and virtualization to manage this complexity and meet regulatory demands for communications. The role of air traffic control automation systems in managing flight order and ensuring aviation safety is discussed in [25]. It emphasizes the importance of reliability prediction during the ATC system design phase and safety evaluation during operation. The focus of the research is on developing models for both reliability prediction and safety evaluation tailored to the general architecture of ATC systems. The paper [26] highlights the crucial issues of communication errors in civil aviation safety and management. It proposes the implementation of a supervisory control and data acquisition system for ATM. This centralized system would facilitate information exchange and aid management systems in making informed decisions for ATM. The factors impacting the operational reliability of ATC communication systems, proposing concepts, and methodologies tailored to the unique characteristics of the ATC communication network are analyzed in [27]. Using the civil aviation communication network as an example, it examines the development of backup systems, evaluation methods, and ideas for reliability management within these critical communication frameworks. The report [28] addresses the limitations of current broadcast radio communication in air traffic control, noting that a significant portion of such communication is dedicated to the procedural complexity of transferring aircraft between sectors. It posits that digital end-to-end communication, akin to mobile technology, will eventually supplant current methods, offering substantial benefits by rendering the internal air traffic control structure transparent to aircrews, with systems automatically connecting aircraft to the appropriate controller. The paper explores the challenges and advantages of this shift and suggests adaptations to existing broadcast standards to simulate an end-to-end communication system in the interim. The integration of sophisticated automatic speech recognition technologies in ATC is discussed in [29]. The paper describes an algorithm to convert speech into ontology instructions and outlines an interface for reliable ATC communication, which accounts for plausibility values, speaker identification, and ambiguous outputs. The report [30] discusses the development and evaluation of a prototypical IP-based voice communication system for air traffic control, designed to connect controllers with pilots via radio. This system integrates telephone and radio services, records communications, and allows retransmission across multiple channels, with the prototype enabling simultaneous connection for two users. The project also tested system latency, revealing inconsistencies in measurement methods, and emphasizing the need for careful selection and application of these methods. The literature reviewed underscores the complexity of maintaining reliability in secure communication systems and emphasizes the continuous need for improvement in their management and operation. However, the gap in the literature becomes apparent when considering the dynamic nature of communications redundancy in air traffic management systems and the specific application of cross-domain resource allocation for enhancing reliability. This paper aims to bridge this gap by providing a comprehensive Markov reliability model for multichannel communication systems. It extends beyond the foundational approaches identified in the literature by offering a granular analysis of system behavior under various operational conditions and resource management strategies, which have not been as thoroughly examined in previous studies.
