100-655079-001 – CMC Electronics Up Front Control Panel (UFCP)
Available now on the Airparts.aero Marketplace.
The CMC Electronics 100-655079-001 is a flight-critical, high-performance line replaceable unit (LRU) that serves as the central human-machine interface (HMI) for the Cockpit 4000 integrated avionics suite. Designated as the Up Front Control Panel (UFCP), this cockpit management hub is positioned directly beneath the glare shield and Head-Up Display (HUD) system, right at the pilot’s eye-level. The 100-655079-001 functions as the primary data entry and control conduit for the entire avionics network. It gives the flight crew direct, heads-up access to flight management system (FMS) parameters, radio communications tuning, navigation sensor configurations, identification friend or foe (IFF) transponder scheduling, and tactical weapons mode selections.
Manufactured by CMC Electronics (formerly Esterline), the 100-655079-001 is engineered around a highly reliable, solid-state electronics matrix encased in a ruggedized, compact housing. The user interface features an array of heavy-duty, tactile-feedback edge switches, numeric keys, and dedicated function keys that are fully NVIS (Night Vision Imaging System) Class B compliant. It incorporates a high-brightness, high-contrast digital display window to deliver instant confirmation of alphanumeric data entry. Operating via redundant digital multiplex data buses, this unit acts as a bus-concentrator panel. It translates physical pilot keystrokes into real-time digital command strings, minimizing pilot workload and keeping critical mission parameters accessible during high-G flight regimes.
The CMC Electronics 100-655079-001 is essential for maintaining flight deck data integrity, system dispatch reliability, and civil-military airspace compliance. Its specialized internal filtering completely eliminates keystroke bounce errors caused by cockpit vibration, ensuring that critical emergency frequencies or transponder squawk codes are input correctly on the first attempt. Sourcing a trace-certified, factory-original UFCP ensures full software-hardware alignment with the core Cockpit 4000 Integrated Avionics Computer (IAC). This removes the risk of communication bus latency, display flicker, or data drops during critical phases of flight.
Key Features
Centralized Avionics Interfacing: Consolidates FMS, COM/NAV tuning, IFF, and weapons management into a single, compact, front-and-center cockpit entry panel.
NVIS Class B Night Vision Compatibility: Features specialized internal lighting and filtered displays that conform fully to MIL-STD-3009, preventing pilot night-vision degradation.
Vibration-Isolated Tactile Switches: Keyboards and rotary entry knobs are built with sharp tactile indents, allowing positive, error-free data entry during low-altitude turbulence or high-G maneuvers.
Redundant Digital Bus Processing: Integrates seamlessly across MIL-STD-1553B and ARINC 429 digital architectures, guaranteeing continuous system communication if a single data bus line fails.
Monolithic Conduction-Cooled Housing: CNC-machined from a high-strength aluminum alloy block to maximize structural stiffness and dissipate heat efficiently without the need for internal cooling fans.

Why Choose 100-655079-001?
Sourcing a genuine, trace-certified CMC Electronics 100-655079-001 UFCP protects multi-role aircraft fleets from sudden data bus contamination and data entry lockups. Non-certified or poorly overhauled panels frequently suffer from micro-fretting along internal ribbon connector arrays or moisture ingress beneath the keypad bezel. This deterioration leads to uncommanded key ghosting, digital bus timing jitter, or total terminal lockup during critical tactical maneuvers. Because the UFCP controls the primary communications and navigation entry pathways, an unexpected hardware failure can sever the pilot’s ability to change radio frequencies or squawk emergency codes, causing severe safety-of-flight emergencies. Utilizing a certified 100-655079-001 module guarantees millisecond response times, absolute data integrity, and uniform cockpit illumination control.
The electronic operation of the CMC Electronics 100-655079-001 turns on the principles of high-speed digital bus multiplexing and deterministic keystroke encoding within an environment exposed to high electromagnetic interference (EMI). The core processing matrix architecture acts as a localized data-bus concentrator node, utilizing high-linearity differential line drivers and isolation transformers to interface directly with the aircraft's MIL-STD-1553B dual-redundant multiplex channels. When a key is depressed, internal low-pass debounce circuitry filters the raw capacitive signal spike, converting the physical contact event into a clean, noise-free binary word map without causing data propagation delay or inter-symbol interference.
The unit’s structural housing is machined from an anisotropic 6061-T6 aluminum alloy substrate, providing high torsional rigidity to withstand intense mechanical stress and high-G maneuvers without warping internal multi-layer circuit card assemblies. To prevent high-frequency radio frequency interference (RFI) from corrupting the internal microprocessor logic, the inner walls of the chassis feature an integrated conductive EMI shielding mesh that forms a localized Faraday cage structure. This shielding safely intercepts external transient voltage spikes and wicks them to airframe electrical ground, preserving absolute data stream trueness across all flight maneuvers.
Note: The CMC Electronics 100-655079-001 is an ultra-critical, flight-governing rotable data management component. Component removal, testing inside electrostatic discharge (ESD) protected grounding boundaries, and system firmware synchronization must be conducted exclusively by authorized avionics technicians or certified Part 145 military defense depots. System integration must align precisely with the target aircraft's structural maintenance blueprints and applicable military Technical Order (T.O.) directives. Following unit insertion into the cockpit mounting rails, the technician must run a complete automated Built-In Test Equipment (BITE) diagnostic cycle and perform a full data bus continuity check prior to certifying the airframe for return to service.
