What does loose fabric primarily affect in terms of aircraft integrity?

• A. Aerodynamics and speed
• B. Weight and stresses
• C. Appearance and aesthetics
• D. Functionality and usability

Answer: (B)

Loose fabric on an aircraft primarily affects weight and stresses. When the fabric covering is not securely attached, it can lead to an increase in drag due to poor aerodynamics, which may not directly correlate with increased weight but influences how the stresses are distributed across the structure. If the fabric is loose, it can cause excessive movement and vibration, leading to added strain on the airframe and covering materials. This added stress can ultimately contribute to damage or failure of structural components over time. Therefore, maintaining a tight and secure fabric covering is essential for ensuring the aircraft's integrity, safety, and performance under various flight conditions.
