Surely if you tell your aeroplane that the temperature is hotter than the prevailing conditions it will give you more power. I'm sure everything that I have flown to date has had a worse performance getting airborne on a warm day than a colder day. A warm day is when I would want more -not less - power.
Now if you told the 'aeroplane' that it was colder than for real, then I would expect it to use/need less power.
