Available now on the Airparts.aero Marketplace.
The CMC Electronics 100-655077-000 is a flight-critical, high-performance line replaceable unit (LRU) that acts as the primary hardware and processing foundation for the Cockpit 4000 integrated avionics suite. Designated as the CMA-5000 Integrated Avionics Computer (IAC), this multi-core digital processing platform aggregates flight management, weapon system computation, primary navigation metrics, HUD driver electronics, and digital multi-function display (MFD) processing within a single, highly ruggedized chassis. Engineered for military advanced jet trainers, intelligence-surveillance-reconnaissance (ISR) aircraft, and light attack airframes, the 100-655077-000 manages the high-bandwidth data fusion loops required to convert raw telemetry into real-time operational flight situational displays.
Manufactured by CMC Electronics (Esterline), the CMA-5000 leverages a modular open-system architecture (MOSA) using standard 6U CompactPCI (cPCI) carrier cards equipped with dual PMC slots. The system features a high-performance 1.1 GHz Freescale PowerPC microprocessor paired with large flash and RAM configurations, a dedicated hardware-partitioned FMS/GPS engine, and certified OpenGL graphics hardware accelerators. Operating under a civil-certified real-time operating system (RTOS), this computing hub enforces complete space and time partitioning. This structural configuration prevents low-criticality non-development flight tracking applications from corrupting safety-of-flight primary flight display (PFD) symbol generation loops, ensuring full adherence to civil airworthiness certification baselines.
The CMC Electronics 100-655077-000 is a vital element for keeping a modern multi-role aircraft mission-ready and fully airworthy under strict international regulatory guidelines. Built to execute continuous automatic background test sequences, its processing framework guarantees ultra-low signal latency while providing robust resistance against high-altitude atmospheric radiation and lightning-induced voltage surges. For procurement directors, defense aviation logistical wings, and military MRO engineers servicing frontline pilot training configurations, acquiring this trace-certified rotable master computer ensures seamless line-bus synchronization and eliminates the data dropouts or intermittent tracking losses linked to degraded or unverified avionics hardware.

Why Choose 100-655077-000?
Installing a genuine, trace-certified CMC Electronics 100-655077-000 core computer is vital to keeping high-performance aircraft safely airworthy and clear of critical glass-cockpit failures. Substandard or unverified rotable processors are highly vulnerable to localized data-bus timing jitter, memory corruption, or phase-locked loop tracking decay when exposed to rapid thermal gradients and high-G maneuvers. If an un-certified avionics core stutters or drops out in mid-flight, it can cause immediate freezing of flight deck displays, uncommanded loss of the primary HUD driver loop, and immediate dropout of the master flight management system. Sourcing a fully traceable, certified 100-655077-000 unit guarantees perfect cross-backplane data mapping, providing absolute software integrity and continuous mission safety throughout demanding low-altitude profiles.
The electronic operation of the CMC Electronics 100-655077-000 relies on the principles of hardware-enforced spatial partitioning and asynchronous digital multiplex deterministic processing within an environment exposed to severe high-frequency interference. The system's processing core architecture utilizes an anisotropic multi-tiered backplane designed to segregate its internal dual 32-bit/66MHz PCI buses. This configuration guarantees that high-rate data transfers from the OpenGL graphics accelerator boards cannot cause resource starvation on the primary FMS processor matrix. Positional parameters from the embedded GNSSA daughter card are continuously processed through dynamic Kalman filter loops, tracking spatial vectors and velocity variations in microsecond intervals.
To maintain total signal isolation and prevent data skew across extensive multi-point runs, the system relies on high-speed superheterodyne differential transceivers on the ARINC 429 channels and high-linearity transformers on the MIL-STD-1553B connections. This layout eliminates common-mode noise and limits localized cable line capacitance. When video feeds from active external sensors (such as tactical FLIR systems) are processed, the system applies real-time hardware-accelerated pixel texture mapping to align the raw video frames perfectly with the vector-driven stroke graphics of the HUD system. This high-precision sensor fusion minimizes latency and preserves true target tracking parameters under extreme airframe angular acceleration profiles.
Note: The CMC Electronics 100-655077-000 is an ultra-critical, flight-governing rotable computing component. Component extraction, handling inside electrostatic discharge (ESD) protected grounding zones, and software baseline loading must be executed exclusively by certified avionics technicians or authorized defense depot facilities. Installation must strictly align with the airframe’s standard Wiring Diagram Manual (WDM) and relevant Technical Order (T.O.) guidelines. Following unit insertion into the ARINC 600 rack tray, the technician must execute a full automated Built-In Test Equipment (BITE) diagnostic sweep and complete an extensive flight control system data bus validation check before certifying the aircraft for flight operations.
