Specifications

waypoint 1. CDI or HSI will also be flagged until both VOR and
DME are valid.
Groundspeed and time-to-station information will not be
accurate unless you are flying directly to or from the VORTAC or
waypoint. You have determined that you want to fly a 112" course
to the first waypoint,
so you place 112" under the lubber line on
your CDI (using the
OBS knob on the CDI) and fly to center the
needle.
Soon after you are on course direct to waypoint
1, your
groundspeed and
TTS will become accurate.
At this time you may also want to check the dent of the VOR
by pulling the ON/OFF/Volume switch to place it in the "out"
position. When satisfied, you can return the switch
to the "in"
position and mute the ident tones. DME ident is also available
if connected to your aircraft audio system.

Waypoint passage
12.You are now passing over waypoint 1. The TO/FROM flag on your
CDI will shift to the FROM position and the needle will hold steady.
If Autopilot coupled to NAV, waypoint passage will be smooth
(wings level).
Your flight plan calls for a course of 132" direct from waypoint
1 to Memphis,
so you use your OBS knob to place 132" under the
lubber line, fly to center the needle and continue your flight on the
outbound course from waypoint 1.
