MODEL 560 INSTRUMENTATION AND AVIONICS
AVIONICS
The standard avionics package includes dual audio control panels, dual VHF COMM transceivers, dual
NAVs, dual RMUs, dual DMEs, dual transponders, ADF, automatic flight guidance system, pilot’s electronic
flight instrument system (EFIS, which is part of the flight guidance system), a GNS-X
L
flight management
system with GPS capability, a standby horizontal situation indicator, a secondary flight display and weather
radar. Included as part of the automatic flight guidance system is altitude preselect, altitude alerting, altitude
reporting and vertical navigation. The system provides Category II equipment capability. An optional traffic
collision avoidance system (TCAS) and a second ADF are available.
VHF COMM - HONEYWELL PRIMUS II REMOTE RADIO SYSTEM
The RCZ-833F integrated communications unit normally operates in the frequency range of 118 to 136
MHz with 25 kilohertz (KHz) and 8.33 KHz spacing. The unit can be strapped to extend the upper range to
152 MHz for operation in parts of the world where those frequencies are used. The RCZ-850 unit is the
communications component of the SRZ-850 integrated radio system. The COM radios are controlled from
the RM-850 radio management unit (RMU), two of which are mounted on the center instrument panel.
COM 1, NAV 1, ADF 1, etc. are controlled by the left RMU and COM 2, NAV 2, and ADF 2 (if installed) are
controlled by the right RMU. The unit being controlled is annunciated on the control display unit of the
RMU. The four radio functions: COM, NAV, ATC (Transponder), and ADF which are controlled by the RMU
are all displayed on page one (main frequency select page) of the RMU. Tuning control for the desired
function/parameter is obtained by pressing the line select key next to that function/parameter. The COM
radio has a memory capacity for up to 12 frequencies to be selected and stored for later use.
CONTROLS AND INDICATORS
Control of the COMM radios is normally through the controls and display located in the upper left
corner of the radio management unit (RMU). Any selectable parameter is changed by pressing the
corresponding line key next to the displayed parameter which brings an amber box (cursor) to surround that
position, which allows it to be tuned by the single controller tuning knob on the bottom of the RMU.
