AUC vs. DUC
In 2022, the terminal AUC was -2.1% (or -8.91 CHF2017, -8.02 €2017) lower than the planned DUC. This results from the combination of significantly lower than planned terminal costs in real terms (-8.6%, or -8.9 MCHF2017, -8.0 M€2017) and significantly lower than planned TNSUs (-6.6%). It should be noted that actual inflation index in 2022 was +2.9 p.p. higher than planned.
Terminal service units
The difference between actual and planned TNSUs (-6.6%) falls outside the ±2% dead band, but does not exceed the ±10% threshold foreseen in the traffic risk sharing mechanism. The resulting loss of terminal revenues is therefore shared between the ANSP and the airspace users, with the ANSP (Skyguide) bearing a loss of -2.9 M€2017.
Terminal costs by entity
Actual real terminal costs are -8.6% (-8.0 M€2017) lower than planned. This is the result of lower costs for the main ANSP, Skyguide (-8.1%, or -7.2 M€2017) and the MET service provider (-20.2%, or -0.9 M€2017).
Terminal costs for the main ANSP at charging zone level
Actual terminal costs in real terms are lower than planned for Skyguide in 2022 (-8.1%, or -7.2 M€2017). However, the differences by nature of costs are distorted by the presentation of the additional costs caused by the change in the capitalisation rule in 2022 (+7.4 M€2017). Indeed, in order for these amounts not to be billed to airspace users, they have also been reported as negative exceptional items in the determined costs, but not in the actual costs (-100% of negative exceptional costs, or +7.4 M€2017).
- the significant difference in staff costs (which is overall of -14.7 M€2017 or -26.4%), can be mainly explained by the evolution of the FTEs and salary assumptions, but it is also due to a reimbursement from the pension fund, although partially offset by the provision for ATCO retirement age transition costs.
