The tactical de-confliction service provides information to the operators or the drones to ensure separation management when flying. The differences with the strategic de-confliction described in U2 are twofold: the drone may receive the information and this de-confliction is set for the in-flight phase. It will be necessary to appropriately define the boundaries with the use of Detect & Avoid capabilities.
