Magenetic deviation

[jford74]

Here's one not to try. Here's the flight plan:
[flightplan]
title=NZNV to AAAS
description=NZNV, AAAS
type=VFR
routetype=0
cruising_altitude=13000
departure_id=NZNV, S46* 25.13', E168* 18.30', +000005.00
departure_position=4
destination_id=AAAS, S78* 0.37', E24* 47.68', +011283.07
departure_name=Invercargill
destination_name=Amundsen-Scott Station
waypoint.0=NZNV, A, S46* 25.13', E168* 18.30', +000005.00,
waypoint.1=AAMQ, A, S54* 31.00', E158* 56.87', +000002.25,
waypoint.2=AADU, A, S66* 41.80', E139* 57.32', +000005.45,
waypoint.3=AAVK, A, S78* 27.85', E106* 51.95', +011336.62,
waypoint.4=AADV, A, S68* 35.00', E78* 15.00', +000002.11,
waypoint.5=AASY, A, S69* 1.40', E39* 39.17', +000003.19,
waypoint.6=AAAS, A, S78* 0.37', E24* 47.68', +011283.07,

If I'm not mistaken, in the Cessna, the GPS is tied to the magnetic heading indicator. If the heading on the GPS is 090, the heading indicator should read the same.

I am not sure if the gps is tied to the heading at all
You sould adjust your heading to compensate for this.
This is what you would do if you were flying this for real.
On your heading indicator there is a knob for this you will need to know which way to turn this so your heading is correct. I am not sure but try using shift z to bring up the fps info as well as what your heading is. But I am not sure if this will be adjusted automatically for you.
In FS2004 there is a set of keystrokes that will do this for you look in your assignments menu

I do bring up the fps using shift Z. The heading on it matched the heading on the GPS course, but the heading indicator showed 200 degrees. I set this heading using the heading adjustment knob and was able to track the GPS course fairly well. At either waypoint 1 or 2 in the flight plan, the heading indicator matched the fps perfectly. I read somewhere that the geomagnetic south pole is off the coast of Antarctica. When I fly from South America to Antarctica, I do not get this deviation.

All of that about the magnetic south pole might be true. But the question is does M$ use the same place. I honestly do not know I have never tried flying over either of the poles. But I have had a message come across telling me that my heading was incorrect and to fix it I had to press a couple of keys  and my heading would change. But this is in fs 2004
