Autothrottles for Light Jets.
Got asked in class today, why don't light jets that have FADEC such as newer CJ's Phenoms etc, why don't they have autothrottles.
I didn't have a reasonable answer so I thought I'd consult my panel of experts. I understand that on airframes where its a hydromechanical fuel controller set up its because of the weight and complexity. But in the newer FADEC controlled engines where the throttles are potentiometers, ie connected to wires and the computer schedules the fuel flow.
Would it make smaller jets more efficient...safer. Should all jets have autothrottles.
