Right on, and this is why I am not hard nosed about less than fabulous teaching skills of those instructors attempting to teach commercial students after untold months of not having such a student. All I ask is they know what they are supposed to be showing, even if they can't nail it due to lack of recent practice. So, if an instructor is using air time to reread the PTS then I think they should do that kind of thing at home. But if they are rusty due to lack of practice, then well maybe the student should try and realize that not many commercial students come by in a given year. I do not see any shame in the instructor being honest about this up front, either. I see check-level instructors where I work that do not really know what the PTS says on some of the maneuvers. My own commercial instructor was badly out of practice on the maneuvers and I suspect he actually had never had a commercial student before me. That's one thing, but to not mention this is a disservice to the student. Both parties need to realize the commercial certificate is a special in this way and make adjustments for it.
