One for the Avionics engineers?
 

I'm trying to find the first aircraft that employed the ARINC-429 data bus and, if possible, what year it was introduced.

Been looking for a while and whilst i can find all sorts of info i cant find anything specific about its introduction.

Any help appreciated

I would hazard a guess.
The 767/757 developed in the early 80s are ARINC 429 -32 bit word technology and was probably the first but I couldn't confirm it

My initial thought was 75/767 but if I recall correctly, and I accept that I may not, the A300/A310 had some use of 429. They, of course, date from 1972/1978

Looks like the Boeing 727 or 37 would be the first aircraft to use the protocol.

Perhaps A310 series would be the first widebody, then ? :)

Cheers guys. I actually found that reference to the 727 earlier but damned if i can find a year it was introduced, ah well, guess mid 70's will be accurate enough:}

Also saw that quote, have my doubts about original 72/737s. Having worked both dont recall 429 on 727-100 or 737-200. Possibly on a very late 727-200 with INS etc.
727-100 EIS 1964
737-200 EIS 1968
737 3/4/5 EIS 1984 - certainly 429 use.
As usual could be having a memory lapse !

I agree Wodrick - surely the 429 standard must have been put in the 27s with the old Carousel (or Litton?) INS units. Nothing in the moldy oldies I can think of with an external data bus.......Maybe the A310 was the first here.

A wrencher or sparky boy from the seventies is what we need. :}

I guess I qualify, I started in 1972 !
A310 was the first course I was Instructed on Arinc 429, later courses assumed knowledge.
As may be guessed my money is on the A310.
