Regulatory requirements for installing FLARM in aircraft

When installing any type of equipment in a type-certificated aircraft, there are mainly two types of legal requirements: First, the equipment has to be approved, and second, the installation itself has to be approved. These two requirements are distinct and commonly mixed up even by aviation professionals. We have published a white paper that explains those two requirements and how they relate to the installation of FLARM. The white paper can be downloaded here.
