bobgardner Posted January 28, 2019 Share Posted January 28, 2019 When did the trim indicators appear on a panel like in the C130J? H model? I model? Are the indicators behind the meter simple dc analog meter movements? Trying to find a link to a tm, want to bid on an rfp for some of these indicators. Thanks!

tinyclark Posted February 9, 2019 Share Posted February 9, 2019 They have been there since day 1. They do work with DC. They are a 3 wire input directly from the transmitter. Quote Link to comment Share on other sites More sharing options...
314FMS Posted February 9, 2019 Share Posted February 9, 2019 It's been a long time since I worked on a C-130, but have some info on the trim tab indicators for an E Model. According to the TO 1C-130E-4 (an IPB I do believe), there were three trim indicators on the pilot's main instrument panel: Elevator Trim Tab, Figure 83 - Index 26, P/N 8DJ49GBV2 Aileron Trim Tab, Figure 83 - Index 27, P/N 8DJ49GAW2 Rudder Trim Tab, Figure 83 - Index 28, P/N 8DJ49GAY2 Hope this is some of the info you were looking to find.

tinyclark Posted February 10, 2019 Share Posted February 10, 2019 5P3-3-26-4 is the tech order the IPB calls out, which is a parts breakdown. There is probably a 5P3-3-26-3, depot level book. Quote Link to comment Share on other sites More sharing options...
bobgardner Posted February 13, 2019 Author Share Posted February 13, 2019 Thanks for the feedback folks. I see the C130J model has a panel on the center console with the 4 trim indicators in an edge lit panel, rather than 4 2" gauges like the older models. Still a little confused about the 3 signals from the transmitter to the indicator. If it was a synchro, those might be s1 s2 s3 400hz ac. If it was just a meter movement, I could see gnd and 0-5V or something. We were trying to respond to a request for quote for the new style 4 indicators in a panel (spare parts for foreign sales or ??), and thats why I was wondering what the signal from the position transmitter was.

bobgardner Posted February 19, 2019 Author Share Posted February 19, 2019 That's exactly what I was looking for Mr N1dp. DC Selsyn. Thanks for the link! 1 Quote Link to comment Share on other sites More sharing options...
