nice idea, but then you have the problem that you measure very close to the earl tablet. i think this will produce very unreliable values, due to small turbulances. I do Paragliding and i would not trust these values, because you have to keep the earl in the free airstream , and when it is just "one dimensional" you have to keep it in the right direction in the free airstream. A good compromise for the Flight Comunity would be a second Pressure Sensor where a Small Tube ( maybe a little bit Flexible?) can be connected and can be bent in the free airstream.
the principal would be the following:
The Tube Measures the "Total Pressure" which is "Dynamic Pressure + Static Pressure"
The Second Pressure Sensor measures just the Static Pressure (Height)
A Software could Calculate the Dynamic Pressure out of this 2 Values which is the Wind Speed
The tube could be detachable and the 2nd pressure port could be also used for gaining more accuracy for Altitude calculation.
A detachable Windmill-anemometer could be also good because it could be connected through the TRRS port, but the disadvantage of windmill-anemometers are that there are moving parts, which are very sensitive and the Speed can not be measured Height-compensated (less Density of the air in great altitude)
for me a second Pressure Port would be the best compromise, and this system also works on different types of Variometers and Aircraft also Measure their Speed through the Differential Pressure Method. Also an Advantage is that it is very lite and Not Power hungry
