OAV ACARS and X-Plane common issues

ACARS not connecting to simulator:
If you are running X-Plane as administrator, chances are you should run OAV ACARS as administrator too in order for it to connect to the simulator.
OAV ACARS installation folder is located at C:\Users\username\AppData\Local\Apps\2.0. There you will find 2 more subfolders with a strange name and inside a folder with the name oava..tion...Enter that one and mark oavacars.exe to run as administrator.

XPlane altitude always 0:
If ACARS is not reading correctly the altitude of the aircraft and is always displaying 0 as a value, open XPUIPCOffsets.cfg with a text editor (e.g. Notepad++) and add the following to the end of the file

Code: Select all

Dataref PosElevation	sim/flightmodel/position/elevation		float
Offset	0x34B0	FLOAT64	3	rw	$PosElevation
Dataref TotalFlightTimeSec	sim/time/total_flight_time_sec		float
Offset	0x04A8	FLOAT64	3	rw	$TotalFlightTimeSec
The altitude will be reported correctly now.

XPUIPC ip address error:
Regarding the IP address error, open XPUIPC.ini, change the Server Address to your computer's IP address and it will go away:

Code: Select all

Server Address = xxx.xxx.xxx.xxx
If your computer is changing IP address periodically set a static IP on your computer or a static reservation on your router and that should rectify this.

As always, if you are still having issues, just report it in this forum.
