AUC vs. DUC
In 2025, the terminal AUC was +2.9% (or +11.12 €2022) higher than the planned DUC. This results from the combination of lower than planned TNSUs (-1.9%) and higher than planned terminal costs in real terms (+1.0%, or +1.9 M€2022).
Terminal service units
The difference between actual and planned TNSUs (-1.9%) falls inside the ±2% dead-band. Hence, the loss of terminal revenues is borne by the ANSPs.
Terminal costs by entity
Actual real terminal costs are +1.0% (+1.9 M€2022) higher than planned. This is the result of higher costs for the MET service provider (+15.1%, or +2.2 M€2022) and lower costs for the main ANSP, DSNA (-0.03%, or -0.1 M€2022) and the NSA (-19.1%, or -0.2 M€2022).
Terminal costs for the main ANSP (DSNA) at charging zone level
Based on the additional information to the terminal reporting tables, the slightly lower than planned terminal costs in real terms for DSNA in 2025 (-0.03%, or -0.1 M€2022) result from:
Lower than planned staff costs (-2.3%), mainly due to the late implementation of some of the measures stipulated in the new social agreement (related for example to new working arrangements and new flexible rostering schemes).
Significantly higher than planned other operating costs (+16.3%), mainly due to acceleration of some operational expenses relating to ATC projects in the main regional airports.
Lower than planned depreciation (-5.0%), mainly due to catching up with delayed RP3 amortization.
Significantly lower than planned cost of capital (-21.8%), due to lower NBV of fixed assets (-23.9%) combined with a lower than planned weighted average cost of capital rate, mainly resulting from lower average interest on debt.
Significantly higher than planned deduction for VFR exempted flights (+6.9%).
Assessment of the actual performance in the charging zone reported by the NSA
The NSA of France provides the following overall assessment of the actual performance in 2025 at charging zone level:
"Actual costs are in line with determined costs (only +1% at 2022 prices).
Actual unit cost is slightly higher than the target (+2.9% at 2022 prices)."
Explanation of the differences between actual and determined costs at charging zone level reported by the NSA
The NSA provides the following explanation:
“Regarding the actual unit costs, 2025 achievement is slightly higher than the target, but this is due to the difference between the actual traffic compared to the STATFOR forecast (-1,9%). The domestic traffic is recovering at a slower pace than expected, compared to international and overflights.”
Recommendations formulated by the NSA to the ANSP (DSNA) to rectify the situation and actions taken by the ANSP
The NSA indicates that:
“No specific recommendation is made by the French NSA regarding costs, as actual costs are perfectly in line with determined costs for 2025.
Regarding the actual unit costs, 2025 achievement is slightly higher than the target, but this is due to the difference between the actual traffic compared to the STATFOR forecast (-1,9%). The domestic traffic is recovering at a slower pace than expected, compared to international and overflights.”
