What effect does increasing induced drag have on aircraft performance?

Increasing induced drag primarily affects aircraft performance by reducing the climb rate. Induced drag is closely related to lift; as an aircraft generates more lift (for example, during a climb), the induced drag also increases. When the induced drag rises, more power or thrust is required from the engines to maintain the same altitude or to climb further. If the aircraft cannot compensate with additional thrust or power, the result is a decreased climb rate.

This phenomenon fundamentally ties into the principles of flight, where drag must be counteracted by thrust to maintain or alter the aircraft's altitude. Thus, the relationship between induced drag and climb performance is critical for pilots, particularly during takeoff or when maneuvering in a climb, since excessive induced drag can limit the aircraft’s ability to gain altitude effectively.

Other options do not accurately reflect the relationship between induced drag and aircraft behavior. Increasing lift and improving fuel efficiency would not directly occur as a result of increasing induced drag; rather, they are often negatively impacted. Enhancing stability typically relates to aerodynamic design features rather than directly correlating with increases in induced drag.
