Arc Mode
In the arc mode, the EHSI only displays 45
degrees left and right of the aircraft present
magnetic heading. The 90 degree arc mode
displays most all of the information repre-
sented in the full compass mode. Figure 16-
41 displays the typical representation of the
EHSI in the arc mode.
Weather Radar and Map Mode
Selecting the WX function from the display
controller automatically places the EHSI into
the arc mode with map and weather radar dis-
played (Figure 16-42). The map mode dis-
plays the flight plan routing information used
by the FMS. The weather radar provides 4
levels of weather return and ground mapping
color levels.
