Beechjet 400A Computer Training Systems (CTSys) Practice Test

The heating (environmental control) system is designed to supply warm air to multiple zones to prevent freezing and icing and to keep surfaces and equipment within safe temperatures. It protects the windshield by providing defog/defrost and anti-ice capability, ensuring visibility remains clear. It also protects the cabin by maintaining a comfortable temperature for occupants and by preventing cold-related issues with onboard systems. The floor area benefits from heated air as well, helping control moisture and temperature in that space. Because heating serves all these areas, it protects all items.
