A great deal also is dependent on the features you autopilot has. Two axis? Alt hold? Auto trim? Do you have a slaved DG? Is there a flight director? I can give the name of a guy in MI that is kind of an autopilot whisperer.

GPSS options with 400A
Patrol Pilot. Thanks for the reply. I have the original equipment list. I'll check it to see if lists the instruments. Also check the part numbers of the instrument in the box of autopilot parts. But I think there is only an AI.

The Nav-O-Matic 400 (Straight 400) had two versions that I am aware of. There was an early model with a little different control head and then the current unit used up to about 1969 I think. It seems the change from the early 400 to the latest 400 was about 1968. Attached are a couple cut sheets of the systems
If someone needs other info on the Nav-O-Matic 400 I have a couple files about these units. Service and Parts manuals and user manuals

Nav-o-matic 400
Herb. Thanks for the pictures. I think I have the system on Fig 3-1. But I'll have to go to the airport to check. I may need the manuals you have. I did download the schematics for the head and computer, from you in the past.

Navomatic (STRAIGHT) 400
Herb.
Thanks for sending me the thread. I checked the autopilot I have and found I have both types shown in the pictures. The one that was installed in my C337 is FIG 2-1 but the other system I have is FIG 3-1. I contacted Autopilot Central (Tulsa)and Mayday (Michigan) they both say that getting those OLD navomatic (straight) 400 can be difficult to fix and or find the parts. It seams that my 400 requires a DG and a AI. The AI I have is the old type pictured. I was hoping to get a more modern AI that shows more details and color coded (blue/brown). Autopilot Central is quoting about $10,000 to get my system working/installed with a DAC converter. The other shop is NOT sure about the overall costs? I have contacted tha Nashville shop yet. But will if the other shops can't help! regards, BILLS |

Navomatic 400 (Straight)
Herb.
Hello again. I'm looking for 1965 Navomatic autopilot manual. Probably the install manual as I'm trying to determine the DG and AI that are required for the 1965 year 400 Navomatic. I downloaded the manual that you had, but it only shows Chapter 3 and Fig 3-1. My 400 is the one with only one trim light on the control head. If you have Chapter 2 and Fig 2-1 I'd appreciate it. Thanks. Regards, Bill Story bstory@pa.rr.com |

Thanks for the reply. Is the AF-520A the amplifier? The reason I'm asking is if that number is for the amplifier? Because my number is CA-520A? Thanks, BILLS PS: Do you have the SECTION 2 manual? The Section 3, which Herb sent to me is for 1968 model year, mine is a 1965. |
