For the bleeds, it depends on how much air conditioning you want. As long as it's on it should be OK. 180kts climb is OK, slow climb is 160kts and fast climb is 210kts. with the slow climb expect 15 degrees pitch up and 3000+ fpm.
April 23, 201313 yr As a dash driver myself, I can say it's all down to performance... With bleeds at max, you're diverting air away from the engines for use by the AC packs (which also provide pressurization)... So if you want to reduce your takeoff roll for whatever reason, setting the bleeds to NORM or MIN will send more air back to the combustion chamber and therefore increase your maximum takeoff power available by a small amount. Doing that however will reduce AC effectiveness. That's why once you're off the ground and safely climbing away from the ground, you can switch it back to MAX to keep the folks in the back happier In reality however, on a hot day, runways are often plenty long enough that you can just takeoff with bleeds in max...
