AUC vs. DUC
In 2023, the terminal AUC was +15.6% (or +20.53 €2017) higher than the planned DUC. This results from the combination of significantly lower than planned TNSUs (-20.3%) and significantly lower than planned terminal costs in real terms (-7.9%, or -0.5 M€2017). It should be noted that actual inflation index in 2023 was +14.8 p.p. higher than planned.
Terminal service units
The difference between actual and planned TNSUs (-20.3%) falls outside 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 .
Terminal costs by entity
Actual real terminal costs are -7.9% (-0.5 M€2017) lower than planned. This is the result of lower costs for the main ANSP, LGS (-7.6%, or -0.4 M€2017) and the MET service provider (-50.1%, or -0.1 M€2017) and higher costs for the NSA (+10.3%, or +0.03 M€2017).
Terminal costs for the main ANSP at charging zone level
Significantly lower than planned terminal costs in real terms for LGS in 2023 (-7.6%, or -0.4 M€2017) result from:
- Lower staff costs (-2.1%) in real terms, reflecting primarily the impact of the inflation index (+14.8 p.p.) since, in nominal terms, staff costs are significantly higher than planned (+9.6%), which is explained by increase in “salaries for Air Traffic Control Officers (ATCOs) and other staff categories”.
- Significantly lower other operating costs (-12.1%), reflecting primarily the impact of the inflation index since, in nominal terms, costs were only slightly below planned (-1.6%).
- Significantly lower depreciation (-15.2%), explained by “commissioning of investments for terminal with longer depreciation schedules”.
- Higher cost of capital (+4.3%), which, since LGS is entirely financed through equity, reflects higher actual asset base used to calculate the cost of capital.
