Forty-seven directions.

Each is shown as a mark on paper and slate, a lockup, and at favicon size. The current mark (a split delta) reads too close to an airline. These avoid filled triangles with an apex and pull instead from what the aircraft does: fixes, sectors, lanes, detections, bearings, the coast.

Number 20, Lanes with aircraft, is in use on the site for now. The previous delta mark is kept at /brand/adelt-mark-delta.svg. Round two (11–30) develops Horizon A (1), Lanes (4) and Detection (8). Round three (31–40) is the Wing A from the sketch: an A whose crossbar is a pair of wings, dipping at the fuselage and reaching past the legs.

Marks are plain SVG in src/data/logos.ts, so variants are cheap.
