GPSS options with 400A

[frank.oconnor19]

I have a P337 with IFCS 400. I went with a G500txi PFD and G5 as backup. Have a GAD43e and GMU out in the wing. I keep the Vacuum System only because it runs the boots for de-ice. The system is fully couple to the A/P will fly with GPSS and will fly approach through GS capture.

I had Carpenter Avionics do an overhaul on the AP last summer. It works great!. If you need I have the manual for the adjustments on the IFSC 400, full service Manual. There are quite a few things you can manage on your own with intercept angles, scalloping on altitude and turn rates. All meant to be done in the air. I looked at a new AP, but 25K to give me the same functions I have already, albeit more accurate, but seems a bit out of line.

That's good to know, thanks.
Did you have to keep your old attitude gyro for the AP? My understanding is that the g500 or g5 can control the AP, but the original gyro attitude indicator must still be connected for it to work properly.

for the benefit of the group, anyone who needs the IFSC Manual I have put it on my google drive, and the link is below.

With the Gad43e installed you can remove ALL mechanical gyros. So that is the system I have. This does require both the 500txi and the G5 as you need a backup to the 500 as PFD. I can tell you the system works great.

Hello everyone. Quick basic question. I have a '65 C337. When I purchased my plane, it came with a Nav400, IN A BOX. I was advised, from a hangar neighbor, that Autopilot Central is the place to have the 400 bench checked/repaired. My question is what instruments drives the Nav 400? The AI, HG or turn coordinator? The reason I'm asking is I'm sure that those instruments have been changed from the originals. So I'm looking at pricing replacement instruments? I don't want to spend the money to install a $30,000 S-tec in a plane that I paid $22,500 for! Actually after buying a overhauled Cont IO-360C and six rebuilt cylinders for the other engine I'm in for over $40,000. But still If I wanted a $70,000 aircraft I'd buy a newer C337, that's better equipped, in that price range.
Thanks in advance!
Regards,
BILLS

So it all depends on where you are based. I am pretty happy with the work done at Carpenter Avionics. Based in the Nashville area at Smyrna. Good work,fair price. They got all of the components working together correctly. Best if you can take the plane to whomever, lots of moving parts....

The attitude and heading indicator. I dig the part numbers out in a bit.
