Turboprop and Autothrottle

[QuEsT147]

Hi

I was wondering why turboprop aircraft dont have autothrottle system, what is the reason for this?

Thanks for answers

On older turboprops the added complexity of the prop control along side the engine control is a factor.

On newer types with FADEC etc it tends to be the use of common type ratings eg the Dash 8 -400 has FADEC so could easily have been fitted with autothrottles (from a technical perspective), the 100 series didn't so the Q400 can't either (from a certification point of view or it would have been a Dash 9)

I´ve read somewhere that the Airbus 400 (?) will have ATs fitted as well. Don´t know about others

If they'd put autothrottle on the Q400, pax and crew would disembark into ambulances everytime - with whiplash injuries!
