When I wish to do a DME update I select a waypoint number for the VOR/DME. Am I correct in assuming that if I choose e.g. waypoint 1, it is a different waypoint 1 to that entered when setting up the navigation waypoints? In other words there could be two waypoint 1's in the INS memory. One used for navigation and the other used for updating.

Gianfraco,

Just curious, if you enter DME Updating mode, can you then use
the card reader and load the ADW or whatever its called, and
thus automatically populate all the DME slots?

Sorry if this is covered, I have done things manually and it works
fine, but I just wondered if it could be made this quick and easy?

Thanks,

J

When you first use the ADEU that is when you enter "all" the DME update waypoints for your entire flight. In other words you only need to do it the once. The other waypoint cards can be entered when necessary while the ADU's are updating. As each DME waypoint comes into range select it on the ADU as per the manuel. Once the ADU is tracking it return the unit to other duties. Don't try to upload normal waypoints from the ADEU whilst the ADU is still in the DME insert mode.
