An aeroplane designed with its wing roots above its wing-tips is said to haveQuestion 2Select one:a.Anhedralb.A low aspect ratioc.A high aspect ratiod.Dihedral

Understanding the Terms

1. Anhedral: This refers to a downward angle of an aircraft's wings relative to the horizontal plane. Wings with anhedral can enhance maneuverability.

2. Dihedral: This describes an upward angle of an aircraft's wings relative to the horizontal plane, which generally increases stability during flight.

3. Aspect Ratio: This is a measurement of the wingspan compared to the average wing width. A low aspect ratio indicates short, wide wings, while a high aspect ratio means long, narrow wings.

Analysis of Choices

• a. Anhedral: This could be correct since the configuration implies a downward wing position.

• b. A low aspect ratio: Not applicable based on the description of wing position.

• c. A high aspect ratio: Also not relevant based on the wing root and tip position.

• d. Dihedral: This would imply that the wing tips are higher than the roots, opposite to what is stated in the question.

Conclusion

Given the description of wing roots being above the wing tips, the correct answer is:

Final Answer: a. Anhedral.
