"For what it's worth, my company prohibits slips (to lose altitude) across our fleets. I was part of that decision, and I'm comfortable with it."
And this decision was based on what?.........The "Because I said so principle." I'm curious...what's your company's policy on hand flying, raw data approaches, appropriate levels of automation, and the like? I've seen many once fine aviators who've forgotten the BASICS of flying. Can you believe a commerical airline pilot with over 25,000hrs of instrument flying can have NO functional crosscheck. They can't trim hands off in a turn or for level flight. They can't hand fly and think, they're task saturated. Guess what? Their out there. And I find they work for companies that set policies like yours. I'd be careful of setting company policies that stiffle pilot skills.
Every pilot needs a bag of tricks. And he needs to inventory that bag from time to time. They don't need micro-managing desk jockeys who take stuff out of their pilot's bag of tricks. BTW, some of the worst flying pilots I've ever seen have been Check Airmen/Instructors. I know what's in my bag? If you're gonna take something out of my bag, you better have a damn good reason. Some better than "Because I said so".
