I found an aircraft performance chart and I stand corrected. At 75% power
the aircraft flies 140 TAS at sea level and 150 TAS at 8K feet. This is 140
IAS at sea level and 124 IAS as 8K feet. I am very surpprised, because I
always thought you would get the same IAS for the same power.

Every pilot is taught that in private pilot training. Those of us that
live at higher altitudes really know this because we deal with reduced
power every day.
