When will some bright manufacturer come up with a flight data "computed airspeed". We fly for thousands of hours at different heights, temps. and weights, with today's computer power it should be possible to take the raw EPR or N1 settings of the OPS Manuals, refine them with saved actual data and get a very accurate computed power setting that would make IAS almost a secondary indication of speed. Add to that the angle of attack indications and I suspect that what you would have would be comparable with today's IAS/Mach No but without the external data derived from pitot and static pressure.
That is after all what simulator systems actually do on a more basic level.
