Finn Willard contributed to the flybywiresim/aircraft repository by delivering a targeted bug fix that aligned the TCAS color logic with the A380 Flight Crew Operating Manual. Focusing on front-end and UI development using JavaScript and TypeScript, Finn corrected the color mapping for TCAS modes, ensuring that TARA and Normal/Above/Below states accurately reflected real-world cockpit cues. This change improved the visual fidelity of the simulation and reduced potential pilot confusion by adhering closely to operational procedures. The work demonstrated careful attention to simulation accuracy and traceability, with the update clearly linked to both the FCOM and relevant training materials.
