I'm still having a terrible time remembering to say "checks" at 500 feet. Oh, the humanity!
Flew with one CA that instead of saying "checks"... to remind himself he would say a different cereal name at 500 feet. It worked, haha.
I still think "hold my beer, watch this" should be a callout prior to initiating any takeoff or landing procedure. Maybe that will come in phase 5.
