Message: [QUOTE="and one, post: 4102036, member: 10475"] My title was Aircraft Instrument Tech to which was added Avionics Tech after a getting a 3 week break from Nam going to Clark AFB to get specific F-4 avionics systems training. I had a lovely time but the avionics on the RF-4C we're significantly different from the non-reconn models. Both had nice integrated systems but many different inputs. Instruments was a lot of remove and replace once the bad part was found, which could be the indicator, the input sensor(s) or in the wiring. Wiring was the worst as airplanes flex, vibrate, leak oil and hydraulic fluid, and harnesses can get burned. With the integrated systems there were many heated discussions between the instrument, radar, nav, and comm shops as to just whose problem it was. When no resolution was found there were a couple of McDonnell Douglas tech reps to help sort things out. If it was a wiring issue requiring major harness replacement they took the lead to get that done. I didn't work them but was a big fan of the C-7, with their funny little tail and the ability to take off and land on short and bad runways. Not big but could get people and cargo into spots even a C-130 couldn't. [/QUOTE]
