Bravo on the rant. Alas, I'm sure the flaps checked twice will be here forever. Also, slight correction...the training department isn't involved in the SOPM. They have SOME input but it is largely flight standards that makes the rules for the training department to teach. There were many instructors not happy with some things in the new SOPM when it came out. Like
@Autothrust Blue said, they removed the ignition on the 200 checklist. I already forget what it was but something was labeled "checked L/R" and there's absolutely no L/R to be checked. Should've been just "checked." Training department had nothing to do with that other than to submit feedback to flight standards.
