SECTION III
INSTRUMENTATION AND AVIONICS
MODEL 560
The MAP format is always oriented to the airplane heading and the airplane symbol is located at the
center of the display. When coupled to the FMS, the NAV route, with up to ten waypoints, can be displayed
to the range limit. When weather returns are selected, range control defaults to the WC-650 Weather
Radar Controller.
PLAN MODE
In PLAN mode the top of the display is oriented to North; a three-inch range ring is displayed and
centered horizontally on the display area. An aircraft symbol is plotted at present position (if present
position is on the display) and is oriented with respect to heading. The PLAN mode display encompasses
360°. Weather radar returns cannot be presented in the PLAN mode.
Traffic COLLISION AVOIDANCE SYSTEM (TCAS) (OPTIONAL)
The TCAS mode allows the TCAS window to be displayed when TCAS is installed in the airplane.
TCAS resolution advisory will be displayed on the PFD (if TCAS II is installed) and traffic advisories will be
displayed on the MFD.
WEATHER (WX) MODE
The WX mode allows the MFD display to be used as a weather radar indicator. In WX mode, weather
data is presented on the MFD and is superimposed upon the normal navigation display. Weather radar can
only be selected for display on the MFD if MAP mode is selected. If the MFD is in PLAN mode, selection of
WX mode will force the display into MAP mode. Range selection is controlled by the weather radar control
on the pilot’s instrument panel. When the WX button is toggled, the progression of selection is: WX on -
WX off. Annunciation of weather mode annunciations, warnings, and antenna tilt angle are provided at
the lower middle left of the MFD display. Annunciations are color coded in magenta, green, and amber
according to the importance of the display. Operation of the weather radar with the weather radar control
is discussed in this section.
Checklist Mode
The NORM button on the MC-800 provides entry into the normal checklist display function. The
normal checklists are arranged in the order of standard flight operations. Button actuations cause
presentation of the normal checklist index page that contains the lowest order incomplete and unskipped
checklist with the active selection at that checklist.
The RCL, SKP, PAG, and ENT buttons and the joystick on the MC-800 provide control of this function
and are discussed under "Controls" below.
The EMER button on the MC-800 provides entry into the emergency checklist display function.
Actuation of EMER results in the presentation of the first page of the emergency checklist index with the
active selection at the first checklist. The RCL, SKP, PAG, and ENT buttons and the joystick provide
control of this function and are described in "Controls" below. These controls perform as described for
NORM with the exception of the action taken upon completion of the checklist. All checklist items are
removed from the page and "EMERGENCY PROCEDURE COMPLETE" is written below the amber
checklist title. This will be cleared when the index is selected. The SKP, PAG and ENT buttons will be
inoperative.
EFIS BACKUP MODES
In case of a symbol generator failure, the side having the failure may be selected to the opposite side
SG. If SG1 is selected it means that the pilot’s symbol generator in his DU-870 is driving all three PFD
displays. SG2 means the symbol generator in the copilot’s DU-870 is driving all three PFD displays. In
these cases the MFD will be normal and both PFD displays will have the same format. The multifunction
display has no complete symbol generator function of its own and its symbol generator is therefore not
selectable.
