In which CODDE will you find the ATA 35-Oxygen System description?

The correct choice indicates that the ATA 35-Oxygen System description is found in CODDE 1. The Aviation Technical Manuals are structured around the ATA (Air Transport Association) numbering system, where specific topics are categorized under designated chapters. ATA 35 is dedicated to the Oxygen Systems found on aircraft, and CODDE 1 serves as the appropriate reference for the detailed descriptions and specifications related to these systems, including their operation, components, and maintenance procedures.

Each CODDE (Configuration & Operational Data Definition for Electronics) contains relevant information, and in the context of the Dassault Falcon 7X, CODDE 1 is specifically structured to contain foundational information on vital systems, making it the correct source for oxygen system details. The other options pertain to different systems or components, not focused on the oxygen system under ATA 35.
