GNS V2 Real Air Legacy P3Dv4.5 autopilot problem (resolved)

[mslim 14]

I've got the GNS500 nicely installed in one of my favorite planes the RA Legacy,. It's starting to work well but I can't get the autopilot to lock on the desired track in NAV mode. HDG works as it should as does ALT hold and VS. I have GPS selected on the NAV select toggle switch on the panel. I try to intercept the desired course at a 45 degree angle.

The HSI needle seems to read correctly but when I engage NAV, the plane goes into a slight bank and starts to circle. I can fudge my course with using the HDG bug and function but I'd like the autopilot to follow the flightplan automatically that I have input into the GPS.

My first thought is maybe I don't have the config panel setup correctly. I have a set of screengrabs but when I try to "insert other media" it can seem to find them.

Hi,

Can you please post the content of the RXP log files? (see RXP User's Manual for file/path)

Log files are not showing anything peculiar.

However this is an older aircraft for FSX only and this might be the root cause, in particular:

- Is this aircraft offering a RXP GNS preset?

If so this is for the older RXP GNS and if you're using this preset, you might have to also enable the following GNS V2 advanced setting: " Use Legacy L:vars with 3rd Party Aircraft"

NB: "Legacy L:vars" is about the legacy RXP GNS, not the Legacy aircraft!

I have GPS selected on the NAV select toggle switch on the panel.

Just to make sure: is the GNS V2 set as "Master Device" and is it in GPS mode as well?

[mslim 14]

GPS was not set as "master device" GNS V2 is in GPS mode. I don't know about the RXP GNS preset. Mutley's Hangar says in their review:

"• Optional RXP GNS WAAS gauge integration (RXP gauges are a separate purchase from Reality XP) with multiple configurations
          (dependant upon the RXP package) including: 1 x GNS530, 1 x GNS430 + 1 x GNS530, 2 x GNS530, 2 x GNS430 or 1 x GNS530 + 1 x GNS430,
          all with cross fill;"

There is a file labeled "panel_200609_042652.gns.rxp in the Panel folder but AFAIK it is not enabled in anyway unles it was enabled by the installation of the RXP GNS V2. It reads as follows:

GPS was not set as "master device"

Well if not, then it won't control the A/P as expected.

Please search for "Master Device" in the RXP GNS User's Manual.

For example:

Each device connects to different instruments independently (example: GPS1 to VOR1 and GPS2 to VOR2). The Master Device has exclusive access when two or more devices, including the simulator GPS, are sharing the same resource (like the autopilot

Got it. Thanks for the help. I enabled the Master Device and now the autopilot tracks the selected flight plan.😃
