Font Selection Checklist

Key questions to consider when choosing fonts for aviation & transportation applications.

1

Is this for safety-critical displays?

Safety-critical applications require fonts tested under adverse conditions (vibration, lighting variations, fatigue).

2

What are the viewing distances and angles?

Font size must be calculated based on viewing distance. FAA provides formulas for minimum character height.

3

Will this be viewed under varying lighting conditions?

Consider how fonts render in direct sunlight, night conditions, and emergency lighting scenarios.

Frequently Asked Questions

What fonts are used in aviation displays?

Aviation displays typically use highly legible sans-serif fonts optimized for clarity under stress. DIN and Helvetica are common choices. Fonts must be tested for legibility under vibration, varying lighting, and at the specific viewing distances of cockpit displays. Custom fonts are often developed for specific aircraft systems.

Are there specific FAA font requirements?

The FAA provides guidelines in AC 25-11B for electronic flight displays, focusing on legibility and rapid information acquisition rather than mandating specific fonts. Key requirements include appropriate sizing for viewing distance, high contrast, and consistency. Certification requires testing under actual operating conditions.
