Genghis,
Cobalt is not making it up. This is the meaning of "complex motor-powered aircraft" as defined by EASA in Basic Regulation 3(j).
It is unfortunate that they chose the word complex as it creates confusion with the common understanding of VP+RG+flaps. However it is important to understand the new definition as it has implications on Ptf, maintenance requirements, etc.
