ADIRS Panel

Flight Simulation Hardware – ADIRS Control Panel

Overview

This ADIRS panel replicates the Air Data and Inertial Reference System (ADIRS) panel found in Airbus aircraft. It includes 3 sets of IR (Inertial Reference) controls, 3 sets of ADR (Air Data Reference) controls, and a central ON BAT indicator.

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

Panel Layout

The ADIRS Panel is structured in a 3x2 grid format:

Top Row – IR Controls:

• IR1, IR3, IR2 (Left to Right)

  • Each IR module has:

    • A rectangular area for a Korry-style dual switch labeled FAULT and OFF.

    • A rotary selector with 3 positions: OFF, NAV, and ATT.

    • Clearly labeled silkscreen for selector positions and function.

Middle:

• ON BAT indicator located centrally above the IR3 module.

• Legend "ADIRS" above the indicator.

• Marked component silkscreen for switch and LED placement.

Bottom Row – ADR Controls:

• ADR1, ADR3, ADR2 (Left to Right)

  • Each ADR module has:

    • Dual Korry-style switch positions (FAULT, OFF).

    • Component footprints for headers and illumination around switch area.

PCB Details

Connectors & Interfaces

J1 – 40-pin Header

• Main interface header.

• Clearly labeled silk for each pin (D0–D39, VCC, GND, etc.).

• Positioned at the top-right of the board for easy ribbon cable access.

Connections

J5, J6, J8 – 5-Pin Rotary Selector Headers

• Three identical headers for reading the IR selector positions.

• Labeled IR1, IR2, and IR3 respectively.

• Mounted centrally under each rotary selector.

K1–K6 – Korry Switch Connectors

• 4-pin headers for each of the six switches (IR1–IR3 and ADR1–ADR3).

• Labeled and oriented to fit OpenA3XX Korry Switch modules.

J7 – 2-Pin Terminal Block

• Power input terminal at the bottom center of the board.

LEDs and Indicators

• 39 yellow SMD LEDs (D1–D39) distributed across:

  • Switch perimeters for backlighting.

  • Selector positions (OFF, NAV, ATT).

  • ON BAT indicator.

• Each LED is paired with a current-limiting resistor (R1–R15) on the front-facing PCB.

Mounting and Assembly

• 4 mounting holes in each corner for panel attachment.

• Screw holes on acrylic and PCB match for sandwich assembly.

• Panel artwork includes alignment marks for:

  • Rotary switch centers.

  • Switch outlines.

  • Legend markings.

Fabrication and Panel Fit

Acrylic Faceplate:

• Laser-etched legends for:

  • IR1, IR2, IR3

  • ADR1, ADR2, ADR3

  • OFF, NAV, ATT

  • FAULT, OFF (for Korry)

  • ON BAT, ADIRS

• CNC-milled cutouts:

  • For 6 Korry-style switches.

  • For 3 rotary selector encoders.

  • For ON BAT indicator.

• Color-coded preview:

  • Red = Front Panel.

  • Blue = Back Panel.

  • Green = Engraving.

  • Orange = Korry Acrylic Labels.

PCB Design Reference

The routing view (KiCad-style):

• Red = Top Layer (signal traces)

• Blue = Bottom Layer

• Yellow = Silkscreen and component boundaries

• All vias and tracks are clearly defined for through-hole and surface-mount components.
