Panel upgrades, wiring archaeology, ADS-B, autopilot gremlins, and the long slow argument about whether to fix the old box or replace the whole stack.
Post the aircraft, the year, and what the previous shop did. Half of every avionics problem is somebody else's undocumented work.

post the aircraft, the year, and what the last shop did to it. no exceptions. i have watched three threads waste a week because nobody mentioned the airplane had a 2011 upgrade that moved half the ground points

Sim tech to avionics, a genuine question. Has anyone found a decent way to log intermittents over time? I am building a spreadsheet of temperature, run hours and fault codes and it feels like something the industry should have solved. Bruno's point about conditions is what started me on it.

Structures asking avionics a favour. When you route a new harness, photograph it before the panel goes back on. Twice this year I have had to open a repair and found a bundle exactly where I needed to drill, with no record of it existing. Two minutes of your phone saves two days of mine.

Sim tech, and a full flight simulator is basically an avionics rack in a room that moves. Same boxes, same connectors, same corrosion, except mine never sees weather and still fails. If you can troubleshoot a panel you can troubleshoot a sim, and the pay is steadier because training never stops.

2004 Cirrus SR20, autopilot disconnects in moderate turbulence but only in altitude hold, never in heading mode. Shop says it is the servo. That does not match the symptom to me but I fix software for a living, not airplanes. Am I wrong?

apprentice question, sorry if its dumb. why do we torque a connector to spec and then safety wire it, if the torque is what holds it? feels like belt and suspenders and i want to understand instead of just doing it

the ADS-B rebate window is long closed and i still get one call a month from an owner who thinks he has until next year. if your airplane is not equipped it has not been legal in rule airspace since january 2020. please
