Stall speed and ISA in a slip
I got into the habit of slipping on final to loose altitude. It's fun for a start and I think it gives me more options should the engine quit: I can get the a/c straight and should make it to the threshold with plenty of room to spare. In some a/c it dramatically improves forward visibility too.
It is all very easy with PA28s and C152s which can loose speed very quickly, so I'd slip at a relatively high speed (5~10kts above normal approach speed) and loose that speed as soon as I straighten up.
I just got checked out in a 182 and found it a bit more complicated, mostly due, I think to the greater speed and weight. I don't think I'll be slipping a C182 as often as I do a PA28 but if I need to I'm curious to find out how people judge slipping speed relative to the stall, specially considering the ASI will be misreading anyway.
Thanks.
