This would require 1) a small accurate (and light!) pressure sensor that would run off a small set of batteries, and 2) a similarly small, light, low-power way to get the information down to earth. I'm thinking of having the output be a tone whose frequency is proportional to the airspeed. Does anyone know of such a system, or where to look for the individual pieces? Comments?? Thanks.
