To ensure that radiocommunications systems of new aircraft function flawlessly, manufacturers need to test the system and verify its functionality in a near-real environment. Aircraft manufacturers often install real air traffic control (ATC) radios to perform the required verification activities.
To operate these radios, they need a compact voice communications system (VCS). VCS test systems provide the relevant operational features and the exact same behavior on the radio frequency, but they do not need to deliver the same performance as the operational systems of air navigation service providers. Flexible, scalable and cost-effective solutions are required.
