Modern military systems are rarely built from a single technology stack. Processing boards, networking modules, storage devices and mission-specific payloads are often sourced from multiple manufacturers, with each defence program requiring a different system architecture. The ability to select the best technologies for a mission creates flexibility, but it also creates complexity. Those technologies must fit together physically, communicate reliably, withstand harsh operating conditions and perform as a single deployable system. CM Computer specialises in the infrastructure that makes that integration possible. Established in 1987, it is one of the longest-standing military-certified chassis suppliers serving defence programs across Europe and the U.S. The company designs and manufactures rugged ATR chassis, custom backplanes and military computing architectures that enable boards, payloads and subsystems from multiple vendors to function within a unified platform. Supporting a broad ecosystem of VPX, VME and cPCI modules, these solutions give defence system integrators and OEMs the flexibility to select the technologies best suited for their requirements. Combining chassis engineering, backplane development, power distribution, I/O integration, thermal management, validation and manufacturing under one roof, CM Computer reduces engineering complexity, accelerates deployment and minimises program risk across airborne, naval and ground applications. "Every military platform presents unique requirements," says Miguel de la Torre, CEO. "Our role is to engineer systems around those requirements, not force programs into predefined configurations."

Flight Simulation Training Service

Dimitris Perdikaris spent much of his career in the training halls of the Hellenic Air Force, serving as an instructor pilot and examiner. His early work—introducing new simulation devices into the Air Force’s training program—reshaped how he viewed technology’s role in preparing the next generation of pilots, to meet demanding operational standards. “Simulation tech helped me prepare pilots for the unthinkable,” says Perdikaris. “It let me place them in situations too dangerous to attempt in real aircraft, yet essential for their growth. That was when I saw the full potential of simulation.” As his career progressed, Perdikaris became both a Flight Simulation Training Device (FSTD) operator and inspector. These roles revealed the lesser-seen side of aviation training: the world of regulatory standards and performance oversight. That experience made one truth clear, most simulators either delivered authentic flight experiences or met certification criteria—but rarely both. Perdikaris founded JETSIMS to close that gap—to merge regulatory precision with the realism pilots truly need. The company’s simulators fulfilled the criteria to strike a balance between technical fidelity and regulatory compliance. Each device is engineered and upgraded, to comply fully with EASA CS-FSTD(A), giving approved training organisations (ATO) and airlines confidence that their realistic training programs carry full regulatory recognition. Trainees step into an environment that feels true to flight—responsive, precise and safe—without compromising compliance. Internally, JetSims maintains a rigorous quality system that tracks device availability, utilisation and restart ratios, ensuring continuous reliability and audit readiness. Even the smallest details are given close attention. Radio communication training, for instance, aligns with CAP 413 standards to ensure cadets use the exact phraseology examiners expect. It may seem minor, but it prevents wasted hours, failed checks and inconsistencies in assessment. “I personally attended the FSTD Inspector Course at the JAA Training Organisation in Hoofddorp, earning certification to ensure full compliance with the latest regulations and standards. I had the honour of being nominated by the Hellenic Civil Aviation Authority and participating in numerous audits. This experience gave me valuable exposure to various synthetic training device technologies, manufacturers, and qualification requirements,” says Perdikaris, CEO of JetSims. For flight schools, that expertise removes a major operational burden. Owning a simulator often means juggling requalification, regulatory audits and ongoing technical checks. JetSims takes that weight off their shoulders, keeping every device flight and examready while instructors focus on producing pilots well-prepared for the complexities of modern aviation.
