To make the licensing procedure easier as well as increase safety standards it is necessary to find a standard in Certifi-cation for small-windturbines. The guideline 61400 includes all relevant details for this development proposal. This paper shows how these guidelines can be used for airborne wind turbines. Thereby we can observe the applicability of ISO 61400 regarding the set definitions (airborne wind turbine = small wind turbines, rotor surface = kite surface), the trans-ferability of components of small wind turbines to airborne wind turbines (see graphic) as well as the safety standards. By accomplishing a certification we achieve better approval by authorities and make the licensing procedure easier. Since only a few components of a airborne wind turbine and a classic windturbine are identical, there is a large need for clarification, how the effect (load) and safety requirements for components such as the rotor can be transferred to a air-borne wind turbine. The claimed static test for rotor blades from the ISO 61400- 23 can’t be used for the Kite. Here we need new innovative thoughts regarding an adaption of the components and we have to consider the fact, that some of the airborne wind turbines are mobile systems.

Adopting the ISO 61400 for airbornewindturbines: In which extent is it possible to make use of existing guidelines for

airbornewindturbines? Is there a way to interpret claimed conditions new/differently?

With regard to innovative approaches, the absence of a rig-id support structure causes not only safty and reliablity is-sues, it also allows to define the wind energy converter in an entirely new way. Therefor the authors will presents pat-end ppat-ending procedures for the operation which will be more in detail explained in the paper and when by then the IP is-sues are clarified.

Up to now, there are lack of experience on the part of the ap-proval-related institutions due to the innovative technology of high altitude wind turbines. Right here must be valued and to develop a method to simplify and speed up the approval proc-ess. To develop and implement this process

there could be obtained a research partner, which already has experience in the field of certification and approval of ad-vanced technologies. The strategy is the practical testing by building representative test sites, which will give character-istic reveals of environmental compatibility, acceptance, and which provides potential risks. First steps towards accept-ance and sensitization are done by having a long-term au-thorization for the flight test operation in the Berlin- Branden-burg region.
