AUC vs. DUC
In 2022, the terminal AUC was -18.2% (or -20.83 €2017) lower than the planned DUC. This results from the combination of significantly lower than planned terminal costs in real terms (-14.0%, or -7.9 M€2017) and significantly higher than planned TNSUs (+5.1%). It should be noted that the actual inflation index in 2022 was +6.1 p.p. higher than planned.
Terminal service units
The difference between actual and planned TNSUs (+5.1%) falls outside the ±2% dead band, but does not exceed the ±10% threshold foreseen in the traffic risk sharing mechanism. The resulting gain of additional terminal revenues is therefore shared between the ANSP and the airspace users, with the ANSP (DSNA) retaining an amount of +1.4 M€2017.
Terminal costs by entity
Actual real terminal costs are -14.0% (-7.9 M€2017) lower than planned. This is the result of lower costs for the main ANSP, DSNA (-14.4%, or -7.6 M€2017), the MET service provider (-6.7%, or -0.2 M€2017) and the NSA (-23.3%, or -0.1 M€2017).
Terminal costs for the main ANSP at charging zone level
Significantly lower than planned terminal costs in real terms for DSNA in 2022 (-14.4%, or -7.6 M€2017) mainly resulting from higher than planned inflation:
- Slightly lower than planned staff costs (-1.5%) due to the inflation index impact (+6.1 p.p.) since in nominal terms the costs are higher than planned (+4.2%),
- Significantly lower than planned other operating costs in real terms (-18.6%) due to lower operational expenditure associated to investments,
- Significantly lower than planned depreciation costs (-33.0%) “due to the redefinition and prioritization of SYSAT programme with a new ATM system for major airports: iATS project at Orly in 2024 and AVVISO system at CDG. The SYSAT contract has been redefined end 2021 / beginning 2022 and some 2022 planned expenditures postponed accordingly” as reported in the NSA Monitoring Report 2022,
- Significantly lower than planned cost of capital (-27.6%), “in line with the decrease of the depreciation costs” as reported in the additional information to the June 2023 reporting tables,
- Significantly higher than planned deduction for VFR exempted flights (+34.2%).
Note: It is understood that DSNA operating costs include costs of investments that are not capitalised (T3 TECH).
