Auto Thrust or Auto Throttle?
Are they actually different? Or is it two different terms for different manufacturers? I can't find a definite answer. Any insights or wisdom would be greatly appreciated.
Re: Auto Thrust or Auto Throttle?
If it helps, only gasoline powered piston engines with a carburettor have a throttle - it’s the plate in the carb that’s angled to a greater or lesser degree across the exit of the Venturi and restricts the air/fuel mixture flow out of the carburettor to control the power the engine develops. It’s not strictly correct to call anything else a “throttle”.
DId you hear the one about the jurisprudence fetishist? He got off on a technicality.

Re: Auto Thrust or Auto Throttle?
Boeing calls the associated automated system Auto Throttle and they're definitely jets. But the actual levers are referred to as Thrust Levers. Go figure.
Auto Thrust is maybe an Airbus term? Dunno.
But it's all semantics really.

Potato Carrot. Dassault calls it Auto Throttle

Same thing.

Re: Auto Thrust or Auto Throttle?
I always understood the term 'autothrottle' to be used on systems where the computer actually moves the thrust levers (like a Boeing).
Whereas 'autothrust' is used in the cases where the computer controls the actual thrust, but doesn't move the levers (like an Airbus).
Perhaps I am wrong though.

Re: Auto Thrust or Auto Throttle?
Cliff Jumper got it, and it's my understanding as well from flying the different types. Autothrottle= Levers move along with the level of thrust commanded. Autothrust= You select a thrust mode by placing the levers in a detent. They don't move.
Embraer and Boeing calls it autothrottle and the levers move. The bus calls it autothrust and they don't.
Makes zero sense linguistically however, and Embraer for one even uses the terms throttles and thrust levers interchangeably in their own literature.

That is not correct. Fuel injected pistons have throttles as well. Look inside a servo next time you have a chance.
