In steady, level flight, list the four forces of flight in their typical order of effect.

• A. Weight, Lift, Drag, Thrust
• B. Lift, Drag, Thrust, Weight
• C. Weight, Lift, Drag, Speed
• D. Lift, Weight, Thrust, Drag

Answer: (D)

In steady, level flight the aircraft moves at constant speed and altitude, so the forces balance: lift supports the vehicle against gravity, weight pulls downward, thrust pushes forward, and drag resists forward motion. The typical order to list them is lift, weight, thrust, drag, which follows the vertical pair first (lift opposing weight) and then the horizontal pair (thrust opposing drag). Since maintaining level flight requires lift equals weight and thrust equals drag, this sequence best reflects how the forces interact to keep the aircraft in equilibrium. The other options either start with the wrong force, swap the vertical/horizontal order, or include a non-force like speed.
