MROair uses Flightaware data to connect groundtime to aircraft atomatically. In the case that a groundtime is not automatically connected to an aircraft you can change it manually. This is done by pressing the airctaft-cin, at the right of every groundtime (groundtie view).
A pop-up will occur. Enter the a/c registration, press the magnifier-button and the right registration will be found. If correct, just press “save”.
