What still needs to be decided?
we get a valid airspeed but calibration needs to be worked out. There was talk of making this dynamic during flight by the GPS and wind estimation. There are two main values, what zero m/s is and the scaler.

What still needs to be done?
The airspeed data gets created by static calibration values but is never used. The meat of the code is in NASA\libDCM\airspeedPitot.x. There is also an analog pin definition in options.h of ANALOG_AIRSPEED_INPUT_CHANNEL

Misc:
Here is a picture of Tom Pittenger (driver) and Phil Giacalone calibrating the airspeed sensor using GPS ground speed while driving in the car.
