For aircraft communications subsystems, which ATA chapter applies?

• A. ATA 23 Communications
• B. ATA 22 Auto Flight
• C. ATA 21 Air Conditioning and Pressurization
• D. ATA 24 Electrical Power

Answer: (A)

Communications subsystems are documented under the ATA chapter that specifically covers Communications, which focuses on the radio and data-link equipment used to exchange information between the aircraft and ground stations or other aircraft. This is why the correct choice is the chapter dedicated to Communications, as it directly addresses the hardware, interfaces, and maintenance considerations for all onboard communication systems. The other chapters cover distinct areas: Auto Flight deals with flight controls and automation systems, Air Conditioning and Pressurization covers environmental control and pressurization, and Electrical Power addresses power generation, distribution, and related electrical systems. While these areas may interact with communications in some ways, they are not the primary chapter for documenting or fixing communications subsystems.
