Can anyone comment on:
- the relative precision of the AoA "from an ADR" and "from an IR"?
Aren't they the same probes, just piped through the aircraft systems differently?
Compared to an airspeed system, an AOA system is significantly more accurate at low (approach) speeds and much less accurate at cruise speeds.(Assuming proper calibration and design.)
Remember that your approach speed is used primarily to infer an angle of attack for the approach.
