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.

Panel Layout

The panel is structured into 3 main zones:

Top Row – EMER ELEC PWR:

• EMER GEN TEST: Test pushbutton with Korry-style label.

• GEN 1 LINE: Switch labeled SMOKE / OFF.

• RAT & EMER GEN: Labeled FAULT with indicator marks.

• MAN ON / AUTO: Korry Switch with AUTO and MAN positions.

Middle Row – GPWS:

• TERR and SYS: Korry switches with FAULT / OFF labels.

• G/S MODE, FLAP MODE, LDG FLAP3: Korry-style switches with OFF and ON configurations.

Bottom Row – RCDR:

• GND CTL: Switch with ON / AUTO legend.

• CVR ERASE and CVR TEST: Pushbutton with circular layout indicators.

PCB Details

Connectors & Interfaces

J1 – 40-pin Header

• Positioned at the top-left of the board for integration with harness or ribbon interface.

Connections

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.
