Runway in use

Sector.mx Labs

Which runway is an airport landing and departing on, right now, read from the motion of the aircraft themselves rather than from any schedule or broadcast. The estimate carries its own confidence, and goes dark when it cannot see.

Estimator design

What it watchesonly low, near-field traffic; everything else is discarded as it arrives

What it keepsnothing raw, each aircraft collapses to a single movement; the configuration is the only state

When it commitsa short rolling window, published only once enough movements agree

How it stays honesta 95% interval on the strip score, so a handful of movements never reads as certainty

MethodThe configuration is inferred live from public broadcast positions only. Arrival or departure comes from each aircraft's vertical trend, the flow direction from its runway-aligned track, and the physical runway from its lateral offset to each centerline. The operational rule of the field is held out as a label to score that last step, never used as an input. The depiction is normal segregated operations; single-runway, opposite-direction, and reduced-mode states are not drawn. Strip roles are provisional until confirmed against the controlling authority.
