P3D is totally awesome using iPads !!! ... and iPhones !!
Even better if you have a couple of iPads and also works with iPad version 1 !
It works with multiple concurrent iPads and even your iPhone LOL !!!
== Installation: == (Its a manual installation copied and modified for P3D)
Step 1
Download the Airtrack Gauge for Flight Simulator X v1.6
http://haversine.com/airtrack/downloads
Step 2
Turn the Flight Simulator off and copy the file airtrackFSX.gau in the directory
C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\gauges
Step 3 (requires administrative rights)
Backup missionpanels.cfg in the gauges directory. ie: rename it to missionpanels.cfg.old
Insert the line:
Window10=AirTrack
in the file P3D_DIR/Gauges/missionpanels.cfg just after the line:
Window09=Countdown
Step 4
add the following lines at the end of the file:
[Window10]
size_mm=25, 25
window_pos=0.01, 0.01
background_color=0,0,0
ident=10099
visible=1
update_rate=10
gauge00=airtrackFSX!AirTrack, 0, 0
Save the file (You will probably need to save the file to your desktop and then move it back to the GAUGES directory). Important: Make sure you save it as a CFG file and not a TXT (if you are using notepad). Saving it from notepad, make sure you save is as an 'all files' and not a TXT type file or else It will tag a TXT extension to your file.
Step 5
Restart P3D and change your view to Cockpit (not virtual) and a small square with a plane should appear on the top left of the P3D screen. Depending on your resolution you may need to hide the menu bar to access it (right click and choose hide menu bar). Click on the image to activate the connection.
In window mode you should see the mention: P3D with WideServer: 1 connected on the title bar.
Step 6
Turn on your iPad AirTrack app and you should see the connection (under Device Location Services): It will show: FSX on 192.168.1.xxx. Click on it to link to your simulation... and Voila !!!
Notes: port used for COMS is 2424. might need to open it (I didn't need to)
