EMER-ELEC-PWR Panel

Flight Simulation Hardware – EMER ELEC PWR Control Panel

Overview

This panel replicates the EMER ELEC PWR, GPWS, and RCDR sections of the overhead panel found in Airbus aircraft. It includes a combination of push-button Korry-style switches for managing emergency electrical systems, ground proximity warnings, and cockpit voice recorder controls.

The hardware design includes a PCB assembly, front acrylic panel, and provisions for illumination and interaction using tactile Korry-style switches.

K1–K10 – Korry Switch Connectors

  • Each switch has 4-pin headers for signal and illumination control.

  • Labeled directly on silkscreen for ease of assembly.

J2, J3, J4 – Test Switches and External Trigger Input

  • 2-pin headers for discrete logic input of test switches (CVR, EMER GEN, etc.).

J5 – 2-Pin Terminal Block

  • Located bottom center for 12V power and GND input.

  • Drives all LED backlighting and switch lighting.

LEDs and Indicators

  • Over 45 yellow SMD LEDs (D1–D52) distributed around the switches and selectors for illumination.

  • Paired with 220-ohm resistors (R1–R18) for current limiting.

  • Centralized switch regions and legends lit via edge LED positioning.

Mounting and Assembly

  • 4x corner mounting holes aligned with front acrylic plate.

  • Panel is designed for sandwich-style installation with easy removal for maintenance.

  • Alignment marks etched for accurate placement of:

    • Korry modules.

Fabrication and Panel Fit

Acrylic Faceplate:

  • Laser-etched legends include:

    • EMER ELEC PWR, GPWS, RCDR

    • FAULT, OFF, ON, AUTO, SMOKE, ERASE, etc.

  • Cutouts accommodate:

    • 10 Korry-style rectangular switches.

    • 2 circular pushbuttons (CVR ERASE, CVR TEST).

    • 1 Korry Switch (MAN ON / AUTO).

  • Color-coded preview:

    • Red = Panel Outline

    • Blue = Backside features

    • Green = Engraving / Legends

    • Orange = Text Engraving and Label Art

PCB Design Reference

  • Red = Top copper layer (signal routing)

  • Blue = Bottom copper layer (returns and secondary routing)

  • Yellow = Silkscreen (component IDs and labels)

  • Vias, SMD pads, and through-holes are clearly annotated.
