Sorry, there are just too many red flags here. Usually the DZ pilots are low time and not the most experienced (and yes, you can "learn fast", but that doesn't mean they learn the full envelope as if you'd been flying for thousands of hours). There's the issue of if you hit a little bump and get too many Gs, the issue of multiple excessive control forces (related to above, depends on if you understand them), and the issue of fuel imbalance due to flying wildly uncoordinated. It seems like the context here is lost. We're not talking about an aerobatic or high time stick-n-rudder pilot in this thread according to the information so far, and I think we have a responsibility as high time pilots to not make flying more dangerous than it needs to be. To say it again, I agree that a high bank angle slip will come down like you describe. I've done it and yep, it works, but in relation to this thread and the fuel issue, it just doesn't seem appropriate. Even if you're a great pilot, it starts to add up risk factors pretty fast. I would want the DZ pilots to exercise some control and maneuvering that is not commonly done in other piloting areas. At 110 or so and 60 degrees of bank, a 182 drops like a rock (especially with the gear down). I seem to remember that 3 turns took 4+K without being super agressive.

Well just repeating my earlier points.. but agreed, high-g maneuvers are not for novices. Don't forget however the average drop zone pilot does anywhere from one to four dozen of the exact same profile in a given day and indeed can get very good at the job. You may see red flags, but with that much practice you could probably swallow swords and juggle burning tennis balls. It's 12 straight hours of practice many days. Same for entering full beta in a King Air on the decent, another "red flag" technique that is done all the time. One can develop a very fine sense of what is safe and what isn't with enough repetition of just about anything, and decades of accumulated experience is also there to draw on.

True enough.
