Universal Avionics Systems Corporation's Radio Tuning Unit
(RTU) is a 2MCU box which provides the interface between the FMS displays and
Collins ProLine II radios for true frequency management (Collins CSDB
Interface). A single RTU allows dual FMS systems to be interfaced with up to
eight radios through the Collins CTL control heads. The eight radios consist of
the following:
1. Three Comm
2. Two Nav
3. Two ADF (single or dual control heads)
4. One Transponder
This frequency
management is designed around the concept of providing an easy method of
selecting, preselecting (4 frequencies) and viewing active channels of radios on
board the flight deck. The CTL control heads and the FMS frequency management
are interactive and require no manual switching for selection of one to the
other. |
