IMHO probably right - more sensors to impact calculations - but at least some sort of visible aural warnings if mismatch gets us to ???
Hmmm-
Nowadays, ADCs are digital. The transducers called Analogue to Digital Interface Units are present near the static and pitot source. The readings are converted to digital signals before the ADC receives the information. The Total Air Temperature has always been an electrical reading as it uses a temperature sensitive resistor which gives out a Voltage.
OK - so at a high temperature near takeoff , the mach calculation would give a LOWER mach number meaning a greater stab deflection ? And if ANY other sensor ( static v dynamic , temperature ) than AOA was incorrect on the same computer as AOA - the old standby match the curve game goes bonkers and ....
