    I don't think it would be nearly that bad. I can't remember what airspeed and descent rate we used to see with full flaps in the 182, but if it was a 2:1 glide ratio, and you were doing 60 knots, you'd need a descent rate of around 3000 fpm. Don't think so.

    Engine at idle or engine windmilling?

    The 2-32 has terminal velocity dive brakes…back then I’d have probably tried it, but fortunately the boss said no. ;)

    That is a pretty good thought...
    Like I said I was just guessing...
    2:1= 30 degree glide so the trig says 80mph (7040ft/min)= 3520ft/min
    3:1= 18.5 degree glide = 2233ft/min
    4:1= 14 degree glide = 1703ft/min
    5:1 = 11.5 degree glide = 1379ft/min

    1970 manual shows a clean glide of about 10:1
    10:1 = 5.7 degree glide = 699ft/min

    looking at those number I am thinking in the ball park of 3:1 is probably what it likely does, still just pretty much guessing.

    Who has easy access to a 182 to try it an tell what the power off (idle) descent rate is at 80mph with full flaps?
    If I get a chance soon a will try to remember to try it.

    I was looking for an excuse to go Wednesday afternoon and now you’ve provided it.

    Of course I get the end of day add on meeting. Maybe this weekend. I no longer use 40 or 30 degree flap settings but can confirm that it drops like a rock.

    At one point someone mentioned that slips weren't recommended in the long body Mooneys. Turns out to be a thing, at low speeds you can wash out the elevators and get a pitch down motion, at least I think that's what it was.

    I've got a 73 182P with sportsman wing and VGs. My VSI only goes to +- 2,000 but its easy to peg it with 40* flaps. But, I'm much slower than 80mph more like 60ish or less. I only use 40* flaps when practicing / doing short field landings, so slower the better.

    Interesting data point, had a friend test this today for me in his 182. Q model I think. Full Flaps power idle he reports 1250fpm. So about 5.6:1 glide ratio for him with full flaps.
    I still want to do some testing myself.

    I can see how slips with flaps would be useful, so that the wearers wouldn't have to pull them all the way up in the john on a cold day.

    I didn’t know slips with flaps existed…I thought it was only the union suits.

    That's more like it.
