For instance, what would it cost to develop an a/s sensing instrument preferable to the Pitot? A device with no sharp bits to collect ice, no moving parts, and a simple mechanism to measure tagged airflow, from release to capture, and compute an a/s correct to tenths of a knot. Not so very much, especially if applied system wide. At first it would be a back up for the current methods, since its strong suit is accuracy in poor Wx. It would no doubt replace all pitots, though GA would most likely not be interested.
rfp172 A Poll then? I vote "Did not want to find". It would be inelegant to call them "Stupid".
