AUC vs. DUC
In the combined year 2020-2021, the terminal AUC was -4.5% (or -39.28 CHF2017, -35.35 €2017) lower than the planned DUC. This results from the combination of slightly higher than planned TNSUs (+0.2%) and lower than planned en-route costs in real terms (-4.4%, or -9.1 MCHF2017, -8.2 M€2017).
Terminal service units
The difference between actual and planned TNSUs (+0.2%) falls within the ±2% dead band. Hence the resulting additional terminal revenue is kept by the ANSPs.
Terminal costs by entity
Actual real terminal costs are -4.4% (-8.2 M€2017) lower than planned. This is driven by the main ANSP, Skyguide (-4.6%, or -8.2 M€2017), while the actual costs of the MET service provider and the NSA are in line with the determined costs (-0.03% and 0.0%, respectively).
Terminal costs for the main ANSP at charging zone level
Actual terminal costs in real terms are lower than planned by -4.6% overall (or -8.2 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 2021 (+5.3 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 +5.3 M€2017).
- the significant difference in staff costs (which is overall of -12.7 M€2017 or -11.4%), is mainly due to the postponement of the “provision for ATCO retirement age”, which was contained in the 2021 determined costs.
