Aileron (Sans-serif, lineal/neo-grotesque)

Aileron by Sora Sagano

"Aileron is a Neo-Grotesque sans serif super-family of fonts inspired by Helvetica. Compared to Helvetica, it has legibility improvements like curved lowercase l to be easily distinguishable from uppercase I.

Dots and periods are circular and follow Euler spiral, giving a soft appearance. While from a design point of view Aileron is close to Helvetica, conceptually it is closer to Univers."
