There are two levers that control thrust in most propjet aircraft making a total of four for two engines.
One lever sets the speed of the jet engine, rpm's, the amount of fuel supplied to the engine.
The other lever sets the amount of blade pitch. This lever is used more than the engine speed lever.
During the takeoff run, the engine speed lever is set at maximum, the pitch lever is set for the maximum "bite" for forward thrust.
Once in cruise flight, the engine speed is backed down to cruise and the speed is adjusted using the pitch lever.
Upon landing, the length of the runway, how fast the aircraft must clear the runway is taken into consideration of the pitch and engine speed settings.
Short runway= Increasing engine speed while setting the prop pitch to reverse and pushing the brake pedal.
Long runway, light traffic= Maybe increase engine speed some while setting the props for reverse, might not even touch the brake pedal.
On the Saab 2000, there are two levers only, one for each engine. The levers control both engine speed and prop pitch combined.
The worst possible situation is where an engine fails and the props cannot be feathered. The means set for the least resistance against the moving air.
The happens ever so rarely. You have one of two large props creating so much drag on one side of the aircraft that it goes into a sharp turn on dives till it hits the ground. Most if not all propjets have "Auto-Feather". If one engine fails, it will automatically feather the dead prop. This is most important when the aircraft rotates, i.e., leaves the ground.
