Some peeks at the "code"

Finally getting some engineering stuff versus the basic things I see in the 'bus manuals.

- We may need to define some terms.

- Smilin' Ed may help us ( a squid golden arm), but the mach corrections to Aoa look a bit harsh to me. OTOH, the plane prolly has an efficient subsonic camber and could be more susceptible to mach effects than what he and I and 'bird and Retired flew.

As several of us have observed, if AoA data is available regardless of speed, we could have a case questioning the design. I ain't going that way........ yet.

- Interesting, the use of tables. Of course, original Viper used analog circuits, so everything was "instant" and the outputs were the result of op amps and function definitions mechanized with discrete components. Outputs were basically voltages. Ten years later the system was digitized. Don't know how the digital system handled frame rates and "mixed" the outputs, but control system technology was moving along at a rapid rate.

thanks for the insight, A33
