I'm laughing at the thought of anyone troubleshooting on a turn. How many placards did LAX put on last month?
Just saying.
Have you ever tried to call Tech and get a placard for an autopilot without knowing which part of the autoland system is causing a problem? I can tell from your post that you haven't. Dumbass's trying to do that is what started the whole MD-80 autopilot fisaco a few years back to begain with. As far as placards go, we don't make the rules, we just live by them. We're mechanics. Our job is to fix them not send them back out broken but we don't have have that choice on a deferable item if we're out of time, just like every other station in the system. Do what you can with the time available, shingle it and away it goes.
