ANTI-ICE Panel
Flight Simulation Hardware – Airbus Overhead Light, Environmental, and Signage Controls
Overview
This panel replicates a major section of the Airbus A320 overhead panel, providing simulation functionality for:
Anti-ice & Probe heating
Cabin pressurization
External lighting
APU control
Interior lighting
Passenger information signs
Designed for realism and full immersion in flight simulation, the hardware consists of a custom PCB, Korry-style illuminated pushbuttons, rotary selectors, and a laser-etched acrylic faceplate.
⚠️ Flight Simulation Only – Not for use in real aviation applications.
