A 10 second loop. Four input tiles appear one at a time: GNSS position, compass heading, IMU attitude and telemetry warnings and mode. Each sends a pulse down to a central check that asks whether the inputs agree. When every input agrees, each tile gets a green tick, the check turns green and the path to Automation OK lights up, with the pilot still ready to intervene. With a compass error or a GNSS error selected, that tile shows a wrong or jumping reading and a red cross, the check fails and the path to Recover lights up instead: hold, simplify and recover. The still frame shows the agreeing case with the decision made.
