A lead mechanic told me to ignore a specific fault code on a G1000 system
He said the 'AHRS ATT' flag was just a quirk on this Cessna 182 and to clear it without looking. I did that for three flights in a row. On the fourth, the whole PFD went blank over Kansas City. Turns out a corroded connector on the magnetometer was causing it, and ignoring it let the issue get worse. Anyone else had a senior guy give advice that almost caused a real problem?

That AHRS flag is a magnetometer warning, not just a random quirk. I saw a similar thing on a 172 where that exact code meant the unit was starting to fail. It's wild he told you to just clear it without even a basic check of the connections. That kind of advice can make a small problem into a big one real fast.

Oh man, that's scary. I had an instructor tell me to ignore a weird fuel flow fluctuation on an old Piper. Said it was just the gauge. It was actually a tiny crack in the fuel line behind the panel. Found it during the annual, but it could have been real bad.
