FLT-CTL Panel

Flight Simulation Hardware – Flight Control Panel (FO Side)

---

Overview

This panel replicates the First Officer's side of the Flight Control (FLT CTL) controls in an Airbus cockpit. It is part of the flight control monitoring interface and includes 4 Korry-style switches for managing and observing the status of ELAC2, SEC2, SEC3, and FAC2 modules.

The design integrates tactile switches and illumination through surface-mount yellow LEDs around each Korry, mounted on a dedicated PCB behind a labeled acrylic faceplate.

Panel Layout

Acrylic Panels

The layout is symmetric and consists of:

• ELAC2, SEC2, SEC3, FAC2

  • Each section includes:

    • A rectangular cutout for a Korry-style dual switch.

    • Legends for each function: FAULT and OFF.

    • LED cutouts positioned around each switch to provide backlighting.

    • Top legends in green and switch labels in orange (engraved and backlit).

A central "FLT CTL" legend is engraved at the top middle of the panel.

Connectors & Interfaces

J2 – 40-pin Header

• Main connection header, located top-right.

• Labeled pins provide connectivity to each switch and LED.

Signal Mapping:

Pin	Signal
1	ELAC2-TOP_LED
2	ELAC2-BOTTOM_LED
3	ELAC2-KORRY_SW
4	SEC2-TOP_LED
5	SEC2-BOTTOM_LED

KR1–KR4 – Korry Switch Headers

• Located near each switch position.

• Each is a 4-pin header designed for interfacing OpenA3XX Korry modules.

J1, J3 – Terminal Blocks

• Positioned on left and right for 12V power and GND.

• Used to power LEDs and backlighting uniformly.

---

LEDs and Indicators

• 28 yellow SMD LEDs (D1–D28), placed in pairs around each switch for backlighting and functional indication.

• Each LED has an associated current-limiting resistor (R1–R9) directly beside it.

---

Mounting and Assembly

• 4 corner mounting holes for attachment to cockpit frame.

• Alignment markers on silkscreen and acrylic panel ensure accurate placement of Korry modules.

• Artwork and milling match the position of:

  • Each Korry switch cutout

  • Backlight LED regions

  • Component boundaries

Fabrication and Panel Fit

Acrylic Faceplate:

• CNC-milled cutouts for:

  • 4 Korry-style dual switches (FAULT/OFF).

• Laser-engraved legends:

  • Top: "FLT CTL"

  • Unit labels: ELAC2, SEC2, SEC3, FAC2

  • Switch labels: FAULT, OFF

• Color-coded visual representation:

  • Red = Outer perimeter (cut outline)

  • Blue = Back plate alignment

  • Green = Engraving

  • Orange = Switch legend fills
