Absolutely , ATCA is 100% owned by Lufthansa Flight training Gmbh , but what would be interesting to know is in which Pilot licencing system they operate , especially their solo flights since the aircraft they use are N registered. If the students are issued an FAA licence to do so, then the medical needs to be re-assessed , as German law does not allow transfer of medical files/ history to a third party. (one of the left over from consequences of WW II). Maybe it is what the lawyers are after .
