ATA chapters are organized by aircraft systems, with each chapter named after the system it covers. When a question asks which chapter corresponds to Information Systems, the direct match is the chapter that carries that exact name. This chapter concentrates on the onboard information processing, avionics data management, software, and data networks, along with the related maintenance procedures. It’s distinct from other chapters whose titles point to different areas: Doors deals with door mechanisms, Fuselage with the aircraft’s primary body structure, and Standard Practices and Structures - General covers broader methods and general structural considerations. So the chapter titled Information Systems is the correct one for that topic.

The main idea is knowing how ATA chapters map to aircraft systems. In the standard ATA numbering, chapter 80 is devoted to the Starting system. That means it covers everything involved in starting an engine—procedures to start, the components that enable starting (like starters, power sources such as the APU or ground power), and related controls and checks. The other topics listed don’t fall under the starting chapter; they belong to different system areas in the manuals. So the subject that ATA 80 covers is the Starting system.

Understanding how maintenance is governed across the operation is tested here. The chapter labeled Maintenance Policy is the place that lays out the overarching rules, responsibilities, and regulatory compliance requirements for all maintenance activities. It sets the framework for how work is planned, performed, documented, and audited, ensuring everyone follows the same guidelines and stays compliant with applicable regulations. Other chapters focus on different areas: Administrative deals with general managerial and procedural aspects, Support covers logistics and services that enable maintenance, and Airplane Statics addresses structural loads and related calculations. None of these target the broad policy and compliance guidelines that govern maintenance as a whole the way Maintenance Policy does.

In ATA documentation, chapters are grouped by the aircraft system or function they cover, and the chapter title itself tells you the subject. When the topic is “in-flight fuel dispensing,” the chapter that carries that exact name is the one that covers it, since it directly identifies the subsystem and its related components, installation, maintenance, and procedures. The other options refer to different systems—nitrogen generation, information systems, and airborne auxiliary power—which belong to their own chapters and do not address in-flight fueling. So the chapter named In Flight Fuel Dispensing is the best match.
