OTHER ATS UNITS CONCERNED

Other ATS units concerned are those that have flights under their jurisdiction which are expected to enter the airspace concerned at a later stage of flight. Those flights could, for instance, require rerouting before entering the airspace concerned. As an example, a special [air-report](https://avioverse.aero/glossary/easa/air-report) concerning volcanic ash or volcanic eruption could be necessary to transmit to [aircraft](https://avioverse.aero/glossary/easa/aircraft) by ATS units in the FIR adjacent to that affected by the air-report.
