Approach profile
A descending glide profile with altitude gates, an accent aircraft stepping down it and lighting each gate tick as it passes.

Airtraffic
15 animationsArrival sequence
A ladder of numbered arrival slots on final compresses as a new accent slot is inserted and the ones below it shuffle down a rung.
CSSConflict prediction
Two converging predicted track vectors extend from their targets until they meet, a closest-point diamond blooming at the crossing.
CSSController handoff
A data tag slides from one controller position box to the next while the accepting box's accept bar fills and the releasing one empties.
CSSFlow rate gate
Traffic arrives on the left at twice the spacing it leaves with, both streams running at the same speed through a metering gate at the channel waist.
CSSHolding pattern
An accent target flies one racetrack circuit round a fix while the inbound-leg timer arc fills and resets at the beacon.
CSSLateral resolution
One track's straight path bends into an offset dog-leg around the other and straightens again once the two have passed.
CSSLevel allocation
Five flight levels with three already occupied; the accent level block is reassigned two levels up, holding at each step, and released back down.
CSSProgress strip
A flight progress strip advances out of the pending bay into the active bay, its state block sliding across the strip as it goes.
CSSRadar vector
A track line pivots round a compass arc from its present heading to the assigned heading, the bug on the arc travelling with it.
CSSRunway occupancy
An occupancy block runs the length of a runway bar while the hold-short bar at the threshold drops and comes back up behind it.
CSSSector ownership
Three adjacent airspace cells light in turn as one accent track crosses them, the owning cell tinting and going clear as the handover passes down the line.
CSSSeparation minima
A dimension rule between two parallel tracks closes toward a hard minimum stop and holds there, the callout bar shortening as the gap is measured.
CSSTransponder code
Four octal code wheels roll and settle left to right, and the ident brackets round the readout bloom as the last wheel lands.
CSSWake spacing
Wake vortices shed by the heavy leader drift back along the track and fade before they reach the follower waiting at the accent spacing marker on the ruler beneath.
