All this whining about no-bleed takeoffs makes me laugh. Spent years flying 1900s and Saabs, always did bleeds-off in the 1900 until 400' AGL, and the Saab was frequently bleeds-off until 1000' AGL. You want to talk about ears popping? Even with the bleeds both on and working, you still had to yawn or chew gum all the way up and down on the Beech.

Even on the 145, packs-off takeoffs in ice are normal. APU shut down, engine bleeds open, packs off is the normal config for icing takeoff. And it's full-body for both 1 and 4, no half-measures. Just glad I'm not paying the bill for fluids!
