(b)
Set the RANGE switch on each EFIS control panel to position the radar targets in the center of each EHSI. 1) Make sure each EHSI have the data that follows:
a) WX mode message. b) Antenna tilt message shows the WXR control panel antenna tilt position.
c) The half range message is the correct value d) The arcs have equal space between them. e) The weather or terrain radar returns are in the
approximate center of the display.
(c) Set RANGE switch on the captain's EFIS control panel to the range above the initial position. 1) Make sure the radar returns move to the bottom of the
