 | | These are the LOM, or locator outer marker, normally located five miles from the end of the runway and the middle marker, located one-half mile from the runway. |
 | | For the configuration shown, outer marker 40 is used as the waypoint, and the magnitude and angle of the C vector along line 58 gives bearing and range to the waypoint. |
 | | Assuming that waypoint unit 88 is set to the outer marker address and waypoint unit 90 is set to the middle marker address, when switches 74, 82, 106, and 114 are set to the "ARM" position (at the begining of an ILS approach,) switches 100 and 102 are set in the # 1 positions. |
