Actions
Cyan = ADS-B, magenta = MLAT. Click an aircraft for full details. Press Focus in its popup to track it: it draws a fading snail trail of where it has been, and if the signal is lost it stays on the map at its last known position (greyed with a red halo) while the panel above keeps its last location, speed, height and heading. Polling continues while this tab is active or when you switch tabs; press Stop to halt.
