    The priority link, which is the link over which commands are send, is determined the following ways:
    - If no link is commanded by the user a regular radio telemetry link is preferred over the high latency link.
    - The autopilot and QGC will fall back from the regular radio telemetry to the high latency link if the vehicle is armed and the radio telemetry link is lost (no MAVLink messages received for a certain time).
