Section: 5.4.2 Scenario
Content: A UAS is approaching the no-fly zone around an airport. Other no-fly zones may be around prisons, highway roads, hospitals, road or crime incidents. The initial authorisation to fly did not contain a route which included this path as the UAV is small enough to not require a route in advance to be granted permission to operate. Or the no-fly zone was temporarily created because of a particular incident. The UAS is transmitting accurate positional information, which may be supplemented by the serving MNO, to the UTM. As the UTM notices that the UAV approaches the edge of the no-fly zone, the UTM decides to send warning to the UAV operator (via the UAV controller) with the details of the no-fly zone. If UAV has reached the edge of the no-fly zone the UTM decides to intervene to prevent any further incursion. The UTM determines a route to remove the UAV from the no-fly zone and provides a route modification to the UAS to achieve this correction. Optionally, the details of the no-fly zone are sent to the UAV controller for user information. The route modifications are transmitted to the UAS and are executed by the UAS to correct the position of the UAV.
