FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

What physical factors are involved in the aspect ratio of airplane wings?

1. Span and chord

2. Weight and lift

3. Length and width

4. Drag and lift

The correct answer is: Span and chord

The aspect ratio of an airplane wing is determined by the ratio of its span (the distance from one wingtip to the other) to its chord (the distance from the leading edge to the trailing edge of the wing). A high aspect ratio indicates a long, slender wing, while a low aspect ratio indicates a short, stubby wing. Therefore, in the context of airplane wings, the physical factors involved in determining the aspect ratio are the span and chord of the wings. In this question, option A is correct because it correctly identifies the physical factors (span and chord) that are involved in the aspect ratio of airplane wings. The other options (B, C, and D) are incorrect as weight and lift, length and width, and drag and lift, respectively, are not the primary factors used to determine the aspect ratio of airplane wings.
