Pitot tube pressure question
Easiest thing is to imagine you're in a motorboat on a river, with a current, driving in circles at a constant water speed, indicated by a water speedometer that measures the dynamic pressure of the water more or less the same way as an airspeed.

Your path relative to the bottom of the river will be a spiral and your speed over the bottom will be faster or slower as you move with or against the current, as you make a perfect circle in the water, but your indicated speed through the water will be constant.

Airplanes are exactly the same.  The air is a big river.  You're just in it instead of floating on top.
