Legend
A 24 hour board for one airport: every expected arrival and departure as a short radial tick at its scheduled time, with the other end of the route written as radial text at the same angle but a different radius. A revised time is a line to the new estimate; an actual time is a line to what happened. Departures run in the outer lane and arrivals in the inner one, each airline in its own colour, with the wind that decides the runway drawn around them. The closest airport is chosen from the dial's place. Not a flight tracker and not a booking board.
Departures outside, arrivals inside: two lanes you can read across the day
A revised or actual time is a line to the new tick, not a changed schedule
The route written radially at the event's own angle, and a colour for each airline
The wind that decides the runway, from 24c Weather
Your calendar still comes with it, on the rim and in the centre hole
The sun's rim
The sun's rim
The rim is the day's light: daylight, both twilights and night, above the airport's day.
Daylight
The sun is up, and the day's own rules apply.
Civil twilight
The blue hour: the sun is down, the sky still carries colour, and lights start to matter.
Nautical twilight
The next step down: the horizon is still there, but the day is over.
Night
The sun is well down and the sky's warmth is gone.
Time on the dial
The hours
The ticks and numbers around the rim are local clock time: one full turn is one day.
Solar noon
The dots on the rim mark the sun's highest and lowest points, so the clock's noon and the sky's noon can be told apart.
The clock shift
The line where the clock shifts: the hour the zone changes inside the day.
Your calendar
Arcs at the top of the day are events from a connected calendar, hung where they fall. They are not the airport board.
The hour spokes
The spokes mark every hour and the dashed spokes every half hour; the one circle outlines the centre hole, as on Events. The board's two lanes sit between them.
The weather
Wind sock
Each sock points downwind, and its orange and white bands count three knots each. The line below it is the day's wind, with the gust area above.
The strongest wind
The number near the rim is the day's highest wind speed, printed where it peaks.
The airport
Arrivals
The inner lane is arrivals: a short radial line at the scheduled time, the origin airport in radial text at the same angle but a different radius, and a line when the arrival was revised or actually happened. Lane, not colour, separates arrivals from departures.
Departures
The outer lane is departures: a short radial line at the scheduled time, the destination airport in radial text at the same angle but a different radius, and a line when the departure was revised or actually happened. Lane, not colour, separates arrivals from departures.
Airline colour
Each airline has its own colour across both lanes; the tick and its airport code share it. Colour is the operator, not the direction.
Revised time
The grey line runs from the scheduled tick to the new estimate; its far end is the time the board now expects.
Actual time
The green line runs from the estimate, or from the scheduled tick when there was no estimate, to the time the movement actually happened.
