Hi aa73,
When we first controlled the revs of a petrol engine, we "throttled" the carburettor by restricting the airflow, we even "choked" it when starting from cold. We've moved on a bit since then.
Capt. Dart. Having flown conventional aircraft & now Airbus A320 series - I still miss the Thrust Lever position feed back, and I miss the feed back in my control wheel when the other pilot is flying - especially near the ground.
I think B777 improved on Airbus, by providing both feed backs.
