I always take off with APU on in the sim. I do not have to pay the fuel. :-)

These days, many airlines opt to take off with packs off - this puts less strain on the engines and you can reduce take-off thrust even more. One method is to simply turn off the packs - this will cause the cabin to be not pressurized, which is not a big deal...unless you forget to turn on the packs again. Another disadvantage is that it gets warm in the cabin pretty quick, so I would not do that in the summer or if you expect to wait for take-off clearance more than a few seconds. A second method is to keep the APU running and supply the packs. The engine-anti-ice needs to be on during taxi already if you encounter icing conditions (<10C, moisture) - and you should turn it on for take-off if you expect to enter low clouds with the TAT <10C. Wing anti-ice is only used if you can visibily see icing on the airframe - so you would not turn in on in anticipation of icing. You need to include it in your take-off calculation if you could possibly need it while climbing out to a safe altitude, though. It does not work on the ground anyway - you could turn it on already, then the valve would open up on lift-off. Jan

It's no problem at all, Ole. Just one button to ban you...many more keystrokes for you to create new emails and continually register. Troll and look insane away.
