Net thrust is best described as thrust that is available to power the aircraft in which condition?

• A. Thrust produced by engine when airplane is stationary
• B. Thrust available to power the aircraft in flight
• C. Thrust after landing
• D. Thrust lost to drag

Answer: (B)

Net thrust is the thrust that remains available to move the aircraft forward while it is actually in motion. It represents the usable push the airplane can rely on during flight after accounting for the engine’s internal losses and the airplane’s drag. This is different from the thrust when the aircraft is stationary, which is not what powers the airplane once it’s airborne. That’s why the best description is thrust available to power the aircraft in flight. The other scenarios describe conditions at zero speed, after landing, or a loss term, none of which capture the usable thrust during flight.
