Drone Sightings Cause Millions in Damage at German Airports

Florian Linke, acting director of the DLR Institute of Air Transport, warns of the effects of even brief disruptions: "Bereits kurze Störungen lösen im hochvernetzten Luftverkehrssystem beträchtliche Folgewirkungen aus". This illustrates how vulnerable the system is even to minor incidents.

Danger to Flight Operations: Figures and Penalties

Drone flights are legally prohibited within a 1.5-kilometer radius of airports and can be punished with custodial sentences of up to ten years. Nonetheless, incidents have been accumulating: In 2024, the DLR recorded 118 reported disruption incidents involving drones, nine of which led to a complete suspension of flight operations. In the previous year, the number of incidents stood at 226, according to the DLR analysis.

Munich Airport was particularly affected. For example, in October there were restrictions at Munich Airport over several days due to drone sightings, affecting around 10,000 passengers. In July, there was also a major incident in Frankfurt am Main. Such large-scale events drive up the damage, according to the study.

Economic Consequences and Demands

The economic consequences for the airlines are considerable: lost revenue from cancelled flights, compensation payments to passengers, and additional expenditure for ground services quickly add up. According to the DLR, the average damage per incident was half a million euros, with individual major incidents such as in Munich 2025 not yet included.

In addition to the direct costs, experts also criticize the security gap: the Federal Police's detection systems have so far only been able to keep pace with the growing volume of drones to a limited extent. Industry representatives are therefore calling for faster approval procedures for defense systems and better coordination between air traffic control, airport operators, and security authorities.

Drones pose a growing risk in civil aviation that can only be contained through a combination of technology, law enforcement, and public awareness, according to the study's authors. They recommend, among other things, the expansion of jamming systems at major airports and a uniform reporting obligation for sightings.
