New Advance Civil Navigation's solutions to increase the compliance of military fighters A/C with civil aviation in future global airspace

The wave of interest since RNAVs (Area Navigation)/RNP (Required Navigation Performance) procedure congestion, that has limited the deployment and operational use of military aircrafts, changed plans: particular attention is devoted to the definition of an Advance Civil Navigation solution applicable to fighters with specific consideration to mandates issued by the main competent authorities for civil aircraft (EASA, FAA, ICAO) and concerning in particular Nav DB, A-RNP, RNP-0.3, RNP APCH, CPDL, ADS-B Out and ADS-B In, RVSM and V-NAV. This is in line with perspectives, new functionalities and applicability to fighters of the SESAR and NextGen proposals which aim to provide growth in various key sectors, including environment, capacity, cost efficiency, safety, and predictability. Following the work done by NATO NIAG SG 222 which provided a Performance Equivalence process for the use of Alternative Means of Compliance aimed at demonstrating the possibility of integrating military aircraft into General Air Traffic (GAT), a survey was carried out on the public domain documentation regarding Human Machine Interface (HMI), avionics, cockpit and operating modes of the navigation system relating to fighter A/C. The purpose of this document is to provide an overview of the civil sector requirements that concern avionic architecture, especially as regard navigation systems, introducing the functionalities and temporal priorities. Through the study of existing military aircraft and a trade off on the reuse of military avionics, it is emphasized how the mandates can be applicable to fighters using customizations and/or mitigations relating to the HMI, Human Factor/Single Pilot aspects, managing to obtain a target compliance level of military aircraft with civil requirements. Indications are provided on the contents, priorities, and introduction to managing change, regarding fighter cockpit configuration, HMI and Single Pilot Workload, necessary for the integration of fighters into GAT, also analysing aspects concerning the approaches to measuring workload and training of military pilots. As the skills required of military pilots in general aviation change, training must also be renewed and adapted to ensure the pilot situational awareness during the flight. To support likely situations of high pilot workload, the concept of aviation actor refocusing (captain, ground operators) and also new key personell have been introduced. Furthermore, an outline of the investment and potential return (cost and benefits) is given, associate to new avionic equipment lauch. That, coupled with a focus on the obsolescence management problem, could be resolved by introducing COTS components in military aircraft. Sharing of civil and military services and convergence of technology are recommended as key elements, as well as a joint consultation for avionics development to facilitate future maximum system compatibility between civil and military applications.
