With the spoilers in the MAX position and flaps set to what degree, may the aircraft show a slight wing dip?

• A. 10 degrees
• B. 15 degrees
• C. 20 degrees
• D. 25 degrees

Answer: (C)

When spoilers are deployed to the MAX position, the airflow over the wing is disrupted, which can cause a change in lift and affect the aircraft's stability. If the flaps are set to the correct degree, specifically 20 degrees, this configuration can lead to a slight wing dip. At 20 degrees of flap, the increase in lift on the wing where flaps are deployed can be overshadowed by the disruptive effect of the deployed spoilers. This combination results in an imbalance of lift between the wings, causing the aircraft to exhibit a tendency to dip towards the side with more lift (where the flaps are deployed), but not as significantly as at higher flap settings. In summary, having the flaps set to 20 degrees is the key factor for experiencing this specific slight wing dip due to the combined effects of increased lift from the flaps and altered airflow from the spoilers.
