Educational familiarization only. This TechOpsBase resource is an original learning transformation grounded in a privately supplied B737 MAX ATA 47 source. It does not reproduce manufacturer task steps, limits, figures or controlled maintenance instructions. Current approved data and aircraft effectivity control real work.
What this resource teaches
An original diagram of the NGS feed-conditioning chain, ASM separation and NEADS route to the center tank.
Follow air quality as well as airflow
The map emphasizes that source air must be controlled, conditioned and kept clean before separation.
Two outputs, one protective objective
The ASM separates the incoming air into NEA and oxygen-enriched air; the NEA path is the one routed toward the tank protection function.
Safety is drawn into the architecture
Check valves, flame arrestor and low-oxygen hazard markers appear because safety boundaries are part of understanding the system.
Evidence-first study method
For any system complaint, separate source/input, control logic, physical response, sensing/indication and consumer/result. When two layers disagree, that disagreement is useful evidence. Do not turn that evidence into a maintenance action until the applicable approved fault-isolation or maintenance data is open.
Approved-data boundary
Educational system explanation only. Do not use this page to perform maintenance, operate aircraft systems, isolate components or determine dispatch status. Current approved maintenance data, aircraft effectivity and operator procedures control real aircraft work.
