Two vocabularies that share an airport. Surface markings are a precise standardised language with a colour rule that unlocks the whole of it — yellow belongs to taxiways and white to runways — and a holding position pattern that encodes the direction of its own rule in the arrangement of solid and dashed lines. Cabin and airframe markings are addressed to people who will act on them under pressure and are written as instructions: where to brace, how to leave by a slide, which panel will not take a foot, where a fuselage may be cut open.
