PA-46-350P, MALIBU
SECTION 7 - DESCRIPTION AND OPERATION (Continued)
MAP DISPLAY (refer to figure 7-7)
The EHI 40 provides two basic types of map; a 360 degree map display
about the aircraft and an approximately 85 degree sectored map display in front
of the aircraft. Options to be displayed on the map include waypoints and
navaids. The type and amount of data presented on the map will depend on the
interfacing equipment. When coupled with an RNAV, such as the
BENDIX/KING KNS 81, waypoints referenced to the selected VORTAC may
be displayed. The map data is provided by plotting VORTAC symbols
referenced to the aircraft using bearing and distance from the VOR/DME.
The following will address only those areas of
the EHI 40 map mode which are different from
the standard compass presentations previously
described.
1. MAP 360 Compass Card Display - The operation of the compass card
remains the same in the map modes as in the standard EHSI display.
To provide more usable display area for map waypoints and navaids,
the 5 and 10 degree tic marks have been reduced in size. The compass
card radius is unchanged.
2.
Symbolic Aircraft Display - The size of the symbolic aircraft is
reduced to provide a cleaner display as the map graphic data is added.
3. Selected Course Display - The alphanumeric course select readout in
the upper left corner of the display functions the same in the map
mode as in the standard EHSI mode. The standard EHSI selected
course is removed from the center of the display. The selected course
pointer is replaced with the course line. If the selected waypoint or
vortac is within map range, it will be displayed with a movable course
line drawn through its center. As the selected course is changed, the
course line will rotate about the referenced point. If the selected
primary nav sensor is an approach approved No. 1 sensor, the inbound
TO course line is green and the outbound FROM course line is white.
If the selected primary nav sensor is RNV, or GPS, the inbound TO
course line is cyan (light blue). Any time the No. 2 sensor is selected
as the primary nav sensor, the inbound TO course line is yellow.
