SECTION III
MODEL 560 INSTRUMENTATION AND AVIONICS
PART TIME DISPLAYS
Part time displays are present when selected on the display controller or the flight director mode
selector panel. The mode and bearing pointers available depend upon optional equipment installed and
may not be present in all installations. Some annunciations also concern other systems, which will be
discussed under headings pertaining to those systems.
Bearing Pointer and
Source Annunciation - The bearing pointers indicate relative bearing to the selected navaid and
can be selected as desired on the display controller. Bearing pointers
appear on the compass rose when they are selected by means of the
knobs on the display controller, and the bearing pointer source
annunciations are in the lower left of the EHSI display. If NAV source is
invalid or LOC frequency is tuned, the NAV bearing pointer and the
annunciation will disappear. The “O” bearing pointer is always NAV 1,
ADF 1, or FMS. The “
~ ” bearing pointer is always NAV 2 or ADF 2 (if
installed).
Elapsed Time Annunciation - Shows elapsed time in hours and minutes or minutes and seconds.
Selection is made on display controller.
Time-to-Go and Ground
Speed - Pressing the GS/TTG button on the display controller alternates
time-to-go (to next waypoint or navaid) and ground speed displays.
Desired Track - When long range navigation is selected, the course pointer becomes a
desired track pointer. The long range nav system will position the
desired track pointer. A desired track (DTRK) digital display will appear
in the upper left corner of the EHSI display. When FMS is selected, the
course selection knob on the remote instrument controller is inactive.
NAV Source Annunciation - Appears in the upper right side on the EHSI presentation when a NAV
(NAV), ILS (ILS), or FMS (FMS) source is selected as a navigation
source. Distance to next waypoint or to selected VORTAC appears
below the annunciation. Annunciated source will be displayed on the
EHSI course deviation indicator (CDI).
Wind Display - The wind display (magenta direction and arrow) is located at the lower
left-center of the display when FMS is selected for navigation.
Weather Radar Modes - Along the left top side of the EHSI display are the displays of the weather
radar modes. These modes and displays are discussed under Weather
Radar in this section.
