    Background

    The aircraft has detected other non-Zipline aircraft in the delivery airspace.

    The alarm will clear on its own once the airspace clears. Delivery will be aborted. No operator intervention is required.

    The aircraft can be immediately returned to service.

    Troubleshooting Steps

    Section titled “Troubleshooting Steps”
    1 action
    If the alarm is recurring, monitor FleetView for air traffic near the delivery site, and wait for the traffic to clear.
