Ray Miller's hints on use of the Apollo GX55 GPS

Fellow Aircrew Members,
For those of you who may be interested, there is a free downloadable copy of the GPS User's Guide at http://www.upsat.com/gxdocs.html
to download: right-click on "GX55 Operation Manual" and from the pop-up select "Save target as." It is a 1.7 Meg file and you will need Adobe Acrobat Reader to view it. I suggest you browse the site as there are other useful files there.
In addition to the excerpts previously distributed by Capt. George Kelen, aircrews may find the following pages useful:
|page 90 -- Marking a position|
|page 91 -- Creating a User Waypoint by US Grid|
|page 92 -- Flying Direct to a US Grid|
A couple of things learned by experience:
YOU select the starting point in the grid. It is determined by the very last digit of the grid selection that you have entered, as follows:
a selection of Grid 364A1 -- would start you at the NW corner of sector A of Grid 364, Grid 364A2 -- would start you at the NE corner, Grid 364A3 -- would start you at the SE corner, Grid 264A4 -- would start you at the SW corner.
If you fly with no grid selected on the GRD soft key, you will still see your course lines as programmed and you will also be able to see all other nav info selected i.e. airports, airspace, find markers, etc.
Of course, you may prefer to fly with the grid lines showing instead, or if you prefer, you can navigate the search pattern using the CDI nav page.
