Rant: My instructor at the academy said to always trust the built-in test on the Garmin G1000, but that cost me a whole day on a King Air last week.
The BIT said the AHRS was fine, but after chasing my tail, I found a corroded pin in the back connector that the test doesn't even check, so what other systems have blind spots like that?

Look at any old plane without a glass cockpit. They fly just fine without a built in test telling them every little thing. A bad pin is a pain, but you found it. The system did its main job. People get too used to the computer doing all the thinking. Sometimes you just have to pull out the book and check the wires yourself.

Ever check the standby attitude indicator after a BIT pass? I've seen the G1000 say all good while the backup gyro was slowly tumbling. The system test doesn't watch that needle.
