Definition#

Thrust is the force generated by an aircraft's propulsion system (jet engine, propeller, etc.) that acts forward along the flight path. It is produced by accelerating a mass of air rearward.

Why It Matters Operationally#

In level flight, thrust equals drag. Excess thrust allows climb; insufficient thrust causes descent. Available thrust decreases with altitude and temperature (density altitude).
