Detailed description

If you intend to erect obstacles to aviation, such as construction equipment or cranes, this can impair air traffic safety. In such cases, you will need a permit from the relevant authority.


Air traffic is most at risk near airfields, airports, or helicopter landing pads. Therefore, the maximum height of your building project depends on its proximity to such a location.

Information

Prerequisites

The obstacle to aviation does not pose a danger to aviation.

Documents required

  • Application with details of:
    • Type of aviation obstacle. For construction cranes and mobile construction cranes, the length of the boom must also be specified.
    • The location of the aviation obstruction is selected in the online portal by precisely moving the pin on the map. Your utmost care is required here. The geographical coordinates of the selected location must be submitted in the application in degrees, minutes, and according to the World Geodetic System 1984 (WGS 84). The permit will refer to this exact location. Applying for and receiving a permit for a construction site is currently not technically possible.
    • Height of the aviation obstacle in meters above ground
    • Date of construction and
  • in case of temporary obstacles:
    • The duration of the project. Special care must also be taken with all other application details (applicant, contact details, etc.) as these will be electronically transferred into the application process.

Please note

If your project already has a building permit and the aviation authority was involved in the process, no additional approval from the responsible authority is required.


Obstacles that are more than 100 meters high always require a permit, regardless of their location.

Deadlines

Submit your application, including all necessary documents, as early as possible.

Procedure

  • You submit the application online with the required documents.
  • The aviation authority obtains expert opinions from Deutsche Flugsicherung GmbH (DFS) and the Federal Supervisory Authority for Air Navigation Services (BAF) if necessary.
