not remain symmetrical during turns. The procedure is listed in table

indicator is used as the controller, the procedure is the
same as given below.
2 Fly to an altitude of 10,000 feet AGL or greater.
3 Set range to 50 NM.
4 Adjust the tilt down until a solid band of ground returns are
shown on the screen. Then adjust the tilt until the green
region of the ground returns start at about 40 NM.
