Current fit-out:
Steam gauge 6-pack.
GNS430W.
Trutrak Vizion 380 autopilot on one of the GNS430W's serial ports.
Trig TT21 ADS-B-Out on another one of the GNS430W's serial ports.
OBS indicator, also connected to the GNS430W.
Note: no devices connected via ARINC, they're all RS232.
Plan:
Upgrade the autopilot to a 385. Trutrak has already confirmed that it's a $500 changeover.
Connect the 385 to the GNS430W on ARINC instead of RS232.
Replace the steam-driven AH with a Garmin G5.
Connect the G5 to the same ARINC bus as the 430W and Trutrak.
Connect a magnetometer to the G5.
My understanding is that that package will yield:
Heading instead of GPS track on the top of the G5's AH and HSI displays.
A heading bug on the G5 which can be used to control HDG mode on the autopilot.
An altitude bug on the G5 which can be used to control altitude select on the autopilot.
Full VNAV, GPSS, etc comms between the 430W and the autopilot, such that the airplane will fly its own holds, procedure turns, approaches to minimums, etc.
I can't believe that I'm the first person to have installed a G5, 430W and TruTrak 385 together.
This is a step in the journey towards converting my night VFR RV-6 to IFR. Hoping to get some wisdom from the crowd about whether my expectations align with reality, and anything else I might have forgotten which I need to accommodate.
Also hoping to have the plan nutted out soon enough that I can acquire the required bill of materials via OSH show specials
Advice appreciated.
Thanks,
