What's the UX in modern airliner avionics for diversion choices, and does it integrate to autopilot?

On a Boeing 777, the pilot can select to have nearby airports displayed on their navigation display (ND). It's the quickest way to get the info IMHO. Of course this data needs to be corroborated with ...

At what point is the input data to glass cockpit PFDs converted to digital?

Glass cockpits are modular systems, and not all of them are exactly the same. But many/most include a module called an Air Data Computer (ADC) which performs the digitalization function for the ...

At what point is the input data to glass cockpit PFDs converted to digital?

On smaller aircraft, the conversion is done within the Air Data Computer (see TypeIA's answer). This makes replacing older steam gauges with a glass cockpit relatively simple because you just send the ...
