Educational familiarization only. This TechOpsBase resource is an original learning transformation grounded in a privately supplied B737 MAX ATA 31 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 from aircraft-system data through DPC processing to display units and the maintenance REAL/MANUAL/AUTO evidence layer.
Operational and maintenance views share infrastructure
The same display system presents flight/system information and maintenance pages, but the user goals are different.
Snapshots are drawn as stored evidence
The visual separates real-time observation from manual/automatic captured events so learners understand why timing matters.
Cross-ATA data is intentional
ATA 21/27/31/32/36/49/71 examples are shown feeding maintenance pages because the MDS is a maintenance observation hub.
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.
