Which ATA chapter covers Indicating / Recording System?

• A. ATA 25 Equipment / Furnishings
• B. ATA 34 Navigation
• C. ATA 29 Hydraulic Power
• D. ATA 31 Indicating / Recording System

Answer: (D)

Indicating and recording systems are the cockpit instruments and data-recording equipment that present information to the crew and capture flight data. In the ATA iSpec structure, each major aircraft system is organized by a chapter number, and the chapter dedicated to these indicators, displays, warning annunciators, and data recorders (like the flight data recorder and cockpit voice recorder) is the Indicating / Recording System chapter. This is why the best choice is the one corresponding to Indicating / Recording System, numbered as ATA 31. The other options point to different subsystems: Equipment / Furnishings covers cabin equipment, Navigation covers navigation-related systems, and Hydraulic Power covers hydraulic systems.
