Deutsche Flugsicherung (DFS) formally requests a fixed annual federal subsidy of 350 million euros starting 2027 to cover sovereign aviation duties. The bundeseigene operator argues the current user-pays model fails during traffic volatility, as roughly 25 percent of costs remain fixed regardless of flight volume. CEO Arndt Schoenemann contends military and security flights, contributing only 5 percent of revenue, should not burden civil airlines. The proposal mandates the state assume 25 percent of the DFS budget, potentially reducing civil air navigation charges. This shift addresses critical infrastructure underfunding risks while aligning with EU Regulation 2019/317, which permits public financial contributions for state-mandated services. Federal review status remains pending.
