UDPP (User Driven Prioritisation Process) allows airspace users to minimise the impact of delay in capacity constraint situations. Actually, the UDPP process solves a capacity constraint by attributing ground delays based on airspace user preferences.
During the lifetime of such a UDPP based Regulation, airspace users can modify their preferences, leading to a changed arrival sequence in the congested airspace (or airport).
SWISS (airline) and Skyguide (ANSP) are studying the possibility to apply the UDPP concept at Zurich airport (LSZH) in a short time frame.
In order to assess the impact of the airspace user actions on the daily work of the Skyguide Flow Manager (responsible for the resolution of hotspots), the validation platform INNOVE was used to simulate a realistic capacity constraint situation at Zurich Airport. It allowed both ANSP and Airspace User actors to use UDPP in a realistic operational environment. Skyguide as well as Swiss were satisfied with the level of realism and with the evidence of operational impact on both actors.
