## What it is
PolarSys B612 is an open source font family designed by Airbus, ENAC, and Intactile DESIGN for maximum legibility on aircraft cockpit screens. It ships as hinted TTF files under the SIL Open Font License.

## Use cases
- find a highly legible open source font for cockpit or instrument displays
- download a free sans-serif font for UI design
- get a font optimized for reading on screens in avionics
- find an OFL-licensed typeface for embedded display interfaces
- use a font with maximally distinct character forms for data displays

## When to choose
- you need a legible screen font for safety-critical or instrument-panel UIs
- you want an open-licensed font for aviation or embedded displays
- you need a typeface with strong character differentiation for data-heavy screens

## When to avoid
- you need a decorative or editorial typeface
- you need a font with active ongoing development
- you need variable fonts or modern font formats beyond TTF

## Facets
- artifact type: dataset
- maturity: maintenance
- function: graphics
- domain: cross-platform, embedded-systems, developer-tools
- platform: cross-platform
- tags: font, typography, open-font-license, aviation, legibility, ttf
