PA Panel

Flight Simulation Hardware – PA and Cockpit Video Controls

---

Overview

This compact panel replicates two functions from the Airbus overhead: the Passenger Address (PA) system and Cockpit Door Video monitoring.

It includes two Korry-style illuminated pushbuttons, mounted on a single PCB and paired with a laser-etched front panel. This design allows for backlit legends and simulation-compatible interaction.

⚠️ Flight Simulation Only – Not for use in real aviation applications.

Panel Layout

Acrylic Panels

This panel includes two modules:

Left – PA Button

• Marked PA with a Korry-style switch labeled IN USE.

• Used for activating the passenger announcement system.

Right – Cockpit Door Video

• Marked COCKPIT DOOR VIDEO with a Korry-style switch labeled OFF.

• Simulates the video system control for cockpit door monitoring.

• Separated by a vertical legend divider for clarity.

J1 & J2 – Power Terminal Blocks

• Dual 2-pin screw terminals on bottom edge.

• Marked +12V and GND.

• Supplies variable brightness LED backlighting.

---

LEDs and Indicators

• 18 SMD LEDs (D1–D18) used for:

  • Button face illumination (top & bottom halves)

  • Panel backlight around each Korry switch

• Each LED is current-limited by a nearby resistor (R1–R6).

---

Mounting and Assembly

• 4 mounting holes, corner-located for secure panel integration.

• Matching holes between acrylic and PCB for easy alignment.

• Switches and LEDs positioned for drop-in Korry unit compatibility.

Fabrication and Panel Fit

Acrylic Faceplate

• Engraved legends:

  • PA, IN USE

  • COCKPIT DOOR VIDEO, OFF

• Cutouts:

  • 2 rectangular Korry switch windows

• Color Coding in DXF File:

  • Red = Front Face Panel Cuts

  • Blue = Back Panel Cuts

  • Green = Laser Engravings

  • Orange = Internal Korry Legends
