AIR DATA COMPUTER TCAS

The KDC 481T is the Central Air Data Computer that processes pitot and static pressures and air temperature inputs for the KAD 480 Air Data System. The processed information is supplied to both the KCP 520 Flight Computer and KAV 485 Altimeter/Vertical speed indicator. The KDC 481T uses a strap module which contains aircraft specific information required for overspeed protection. The Central Air Data Computer is also capable of supplying  air data information to optional Navigation Management Systems.

Features

• This KDC 481T includes TCAS functionality.
