In aviation, what does the term "reverse thrust" refer to?

The term "reverse thrust" specifically refers to the thrust produced in the opposite direction during landing. This mechanism is typically employed by jet engines or propellers to help slow down the aircraft after touchdown. When deployed, reverse thrust changes the direction of the engine's thrust from forward to backward. This contributes significantly to reducing the landing roll distance and enhancing safety during landing, especially on shorter runways or in adverse weather conditions. Using reverse thrust can aid in achieving a safer and more controlled deceleration immediately after landing, allowing for a more effective braking process.
