Piper Arrow III JF - autopilot nav issue

[szymek2392]

Hi there,
does anyone have a problem with GNS 530 on Arrow III where aircraft does not follow flight path on autopilot despite having all set up (AP ON, HDG ON, Rotary Switch: NAV and CDI GPS). HDG, ROLL works ok but airplane just not reacting to NAV mode.

Any ideas?

@szymek2392 Yes I have the exact same problem. Thought it was just me as I hadn’t heard anyone else with a similar problem. I’m on Xbox btw

@onegoodknock Yes, guys on mfs forum also replicated this issue. I guess this aircraft needs update when it comes to gns 530... guess aau2 broke AP.

@szymek2392 interestingly if you switch to the very basic Garmin unit (can’t remember it’s name) the plane will follow the flight plan.

I can confirm having the GNS 530 selected breaks several autopilot functions.

1. GPS course isn't followed.
2. Turning on AP or turning on HDG both lock up the trim (which can usually be freed by toggling VS HOLD on/off).
3. Roll knob makes > rate 1 turn, no matter how little/much the knob is turned.

Working Title advised us a long time ago to remove their addons as they were being incorporated into the default sim avionics so maybe still having it in the aircraft causes a conflict?

Same here, this is quite painful for users in xbox as we have no 750 alternative.

Are you sure the AP is even getting turned on...in ANY mode? Since this last update, the AP has never turned on for me...not even just a simple roll or heading mode...it's never on.

Had confirmation today from Just Flight support that the last Sim update broke some of the autopilot functions and they are working on an aircraft update to fix it.

So it's now 12 September 2024. @Martyn can we take it that there will be no further work done on the Arrow to resolve AP issues?
