February 4, 201214 yr I noticed that de ice, heating, ice door, have no effect on fuel consumption. There should be a consistent difference, expecially at high cold altitudes. Am I doing something wrong?Thanks.Igor. Igor Bischi
February 5, 201214 yr Author Bstolle, If you read this flying tips from real pa46t pilot:http://www.pa46t.com/index_files/Page385.htmhe says that at cruise level, in a typicall winter day, he has to set 900 lbs of torque instead of 800 because of heating.It is a considerable difference I think.

February 5, 201214 yr Because the engine isn't delivering enough bleed air at the combination of low torque and low temperature.You have to increase power manually simply to get a higher bleed air flow from the engine to keep the temperature up.But increasing the temperature itself has nothing to do with a loss of performance etc..

February 5, 201214 yr Author Ok, thanks!Your explanation sounds very good. Next time I'll fly in cold weahter I set 900 torque and light my stove :-) Igor Bischi
