Yeah, back when I was flying King Airs we got a new boss. After a few weeks he held a meeting to discuss how we were doing things. Everything from uniforms, office duties, standard callouts and procedures, and even checklist usage came up. He didn’t want us using slang or doing our own thing with the checklist. Hey, that’s fair, we all agreed. About an hour later we had a flight and the very first god damned thing he does is start using nonstandard checklist call outs. I still remember holding the paper checklist when he starts with “I’ve got 2 up, 2 down, lights, Ice and bleed air.” I’m looking at the checklist and just say “I have no idea what any of that means.” To his credit he went back and said it properly, more or less (at least I could follow along somewhat with the checklist). I did get a talking to about how I could have handled,ed that in a more professional way.
