Aircrew is a neutral, humanist sans-serif family optimized for signage applications in display sizes. Its large x-height enhances readability and its letterforms help distinguish characters from each other, increasing legibility. Aircrew has vertical terminals, low contrast, and short ascenders and descenders. The weight variations between uppercase and lowercase characters provide the perfect balance and its slightly condensed proportions allow more words to fit in less space. There are two different versions of Aircrew, positive and negative. This avoids optical effects that cause uneven thickness and unsteady readability in either light or dark backgrounds.
