Airworthiness Test Method of Ka-band Satellite Communication System for Civil Aircraft

Broadband satellite communication is one of main means of communication in civil aircraft cabin. This paper focus on broadband satellite communication system with Ka frequencies, giving a brief introduction firstly and then starting with CCAR25 airworthiness regulations, analyzing the airworthiness provisions that the system needs to meet, and discussing the method of conformity verification. Then, from the two aspects of ground test and flight test, the test method of Ka broadband satellite communication system to demonstrate the conformity is introduced in detail.
