Runways raised: a board with the streets, water, taxiways, aprons and terminals engraved, the runways raised on top as one piece with their numbers, threshold bars and centre lines engraved into it, and a raised plaque with the code big along the bottom. Engraved: one board with everything burned in, the runways drawn in outline with their markings. Printed: one board in full colour on a UV printer, as an airport diagram (black runways, white markings) or in sectional-chart colours (runways magenta or blue, like a VFR chart).
