ehhh
It's really too bad that the cessna "slip myth" has scared one too many green students as well as those new to something as stable as the cessna 172/182's.
I've heard them all. Slipping with full flaps is dangerous! the plane will flip over! You'll lose your elevator and lawn dart into the ground!
No, no, no you won't. You'll get down faster and have used a sometimes priceless tool for hitting your spot whether it be an actual emergency, a spot landing for a checkride, or if you just like falling out of the sky on final just for the hell of it.
As stated previously, the only reason that placard (s/p?) is there is for the occasional bufffeting you get which could alarm someone not expecting it. Hell, I've heard of people writing incident reports because that 'buffeting' is not part of normal operations.
Who gave these people pilot's liscenses?
Stop scaring people with this myth that it's even SLIGHTLY dangerous or shouldn't be done. I'm not perfect, if I fly 5 diff airplanes on and off, my spot landing in a 172 might require a little slipping if I've been flying a seneca all week. Just don't stall
