Need Installation Manual for 400A Autopilot

[Dan schultz]

There are five wires to connect to the autopilot controller. I am out till late he 15th. I used Approach Fast stack for my wiring harness. My GNS530W is connected to the 400A. I can tell you the wires to connect when I get back.

I don’t think my 69 T337D AP has any external inputs for pitch etc.
Except from the artificial horizon or small control head.

It may just be an “A” model?

AP has the small control head center stack down by pilots right knee.

Control head has a heading bug there, as well as pitch / turn center and controls.
Also has an altitude HOLD switch.
Activates pressure sensor in computer to “hold” altitude
At whatever pressure altitude present when switch is flipped.

If there is a vertical interface, that would be interesting.
Not critical, but interesting.

As you know 337 so stable, barely ever use AP.

Dan, I’m quite interested in your 530w solution as I also have 400A AP working fine in HDG but apparently not functional in NAV(GPSS). Look forward to your return!

Ok, I am using an Approach Fast Stack hub. My 530W is only integrated with my NSD360 HSI. My Auto pilot computer CA-530A,

From the computer:

Nav1 Right is pin B
Nav1 Left is pin A
GS +Up is pin C
GS +Down is pin D
ILS/GPS Approach a

Rick,

If you haven't sorted this out yet let me know what you need. I just went through this design stage for my 73 with a 400A and can probably help with any questions you have. I have all the manuals as well if you need specific pages.

Thank you J, I hope to get into this part of the project next week...
