Which statements about an aeroplane leaving ground effect are correct or incorrect?

• A. 1 is incorrect, 2 is incorrect.
• B. 1 is correct, 2 is correct.
• C. 1 is correct, 2 is incorrect.
• D. 1 is incorrect, 2 is correct.

Answer: (D)

When considering the dynamics of an aeroplane leaving ground effect, it's important to understand the implications of both lift and drag changes that occur at this stage of flight. Ground effect refers to the increased lift and decreased drag that happen when an aircraft is close to the ground due to the interaction of airflow with the ground surface. The first statement likely refers to the aerodynamic properties and behavior of an aircraft when it transitions from ground effect to free air. When an aircraft leaves ground effect, it typically experiences a decrease in induced lift due to a reduction in the ground proximity, as the aircraft is no longer benefiting from the advantageous airflow characteristics provided by the ground. This transition can necessitate an increase in angle of attack to maintain performance, which correlates to the idea that the first statement is incorrect. The second statement would be related to how pilots manage the aircraft controls during this critical phase. As the aircraft exits ground effect, pilots need to be prepared for the change in lift and adjust their inputs accordingly. This readiness to manage the controls and maintain needed airspeed supports the correctness of the second statement within the context of effective pilot response and control during this transition. Thus, the choice that asserts the first statement is incorrect while the second statement is correct distinctly aligns with the
