ATA 84 is associated with which topic?

• A. Fuel Cell Systems
• B. Engine Water Injection
• C. Charts
• D. Propulsion Augmentation

Answer: (D)

Propulsion Augmentation is the topic being tested. ATA 84 covers systems and devices that boost engine thrust beyond normal operation, used to improve performance during takeoff or climb, such as thrust augmentation methods and related components. That broader category is why it’s the best choice: it represents the entire area of propulsion-increasing technologies, not just a single system or a non-propulsion topic. The other options don’t fit this category: charts refer to documentation and flight references, which isn’t a systems topic; fuel cell systems pertain to power generation rather than augmenting propulsion; engine water injection is a specific method of propulsion augmentation, but it’s a particular technique within the broader ATA 84 topic.
