The many suggestions of using GPS and/or INS for backup airspeed come up short when it comes to correcting for wind, especially in turbulent conditions with the up and down drafts throwing off vortices.
I modestly propose force transducers on the radome mounts. The forces from the transducers could be algebraically summed to produce a net force which could then be processed against radome drag coefficient to produce airspeed.
Differentials between opposite sensors could even be used to derive AOA and yaw.
I hope those suffering boredom from trawling through the hamster wheel may have found some amusement
