Design system · v1.0

Clear by design.
Built for aviation.

The fly.ae interface is precise, compact and calm. It uses strong hierarchy, technical navy, generous white space and explicit status colours so every action stays easy to scan.

01 · Foundation

Brand and colour

Navy carries the brand and primary actions. Supporting colours are functional: green confirms, coral warns, and sky blue identifies structured aircraft content.

Primary lockup

Use the fly/infinity loop mark from the UI Kit. The legacy airplane mark is not part of the product. Keep clear space equal to the height of the “f”.
