AUC vs. DUC
In 2023, the terminal AUC was +14.7% (or +56 CHF2017, +50.4 €2017) higher than the planned DUC. This results from the combination of significantly higher than planned terminal costs in real terms (+14.1%, or +14.4 MCHF2017, +13.0 M€2017) and slightly lower than planned TNSUs (-0.5%).
Terminal service units
The difference between actual and planned TNSUs (-0.5%) falls inside the ±2% dead band. Hence loss of terminal revenues is borne by the ANSPs .
Terminal costs by entity
Actual real terminal costs are +14.1% (+13.0 M€2017) higher than planned. This is the result of higher costs for the main ANSP, Skyguide (+15.9%, or +13.9 M€2017) and lower costs for the MET service provider (-21.3%, or -0.9 M€2017).
Terminal costs for the main ANSP at charging zone level
Significantly higher than planned terminal costs in real terms for Skyguide in 2023 (+15.9%, or +13.9 M€2017). However, the differences by nature of costs are distorted by the fact that the Skyguide’s costs include significant amounts linked to the additional costs caused by the change in the capitalisation rule in 2023 (+5.9 M€2017). However, in order for this amount not to be billed to airspace users, it has also been reported as negative exceptional item in the determined costs, but not in the actual costs (-100% of negative exceptional costs, or +5.9 M€2017). Other deviations result from:
- Significantly higher other operating costs (+46.6%),due to higher purchased services and products than planned, primarily due to Skyguide’s response to a 22% increase in technical incidents over the last three years. In the short term, Skyguide increased spending to enhance technical systems. Additionally, Skyguide faces compliance issues and substantial backlog in various areas, including technical systems and infrastructure, necessitating additional costs;
- Lower depreciation (-3.1%); and,
- Higher cost of capital (+4.6%), mainly due to a higher fixed asset base and equity ratio;
