Which ATA chapter deals with the geometric dimensions and areas related to aircraft surfaces?

• A. Airplane Statics
• B. Dimensions and Areas
• C. Leveling and Weighing
• D. Towing and Taxi

Answer: (B)

The idea being tested is which ATA chapter is dedicated to the actual measurements and surface geometry of the aircraft. The Dimensions and Areas chapter is the one that compiles the standards for geometrical data—how surfaces are sized, where features are located, and how to calculate the areas of skin, panels, openings, and coatings. This information is essential for accurate drawings, repairs, coatings, and inspection planning, since you need precise dimensions and surface areas to fit parts correctly, determine painting or corrosion areas, and lay out repair boundaries. Other options focus on different topics: Airplane Statics deals with forces in equilibrium on the aircraft, Leveling and Weighing covers leveling and weight-and-balance tasks, and Towing and Taxi addresses ground handling and movement. None of these center on the geometric dimensions and areas of aircraft surfaces, which is why Dimensions and Areas is the correct chapter.
