NAS data layer
Reports Q&A
Ask the NAS picture in plain language. Answers are composed from industry-standard reporting records — arrival lists, flight summaries, route conformance, TBFM configuration, TMI advisories — each one sourced, confidence-tagged, and appended to the hash-chained decision record.
R
This is the layer descriptive reporting dashboards don't have: the same data structures answering questions instead of populating displays. Ask why arrivals held, what a TMI is costing, or where the next two hours are going. Every query and answer is recorded to the audit chain. Advisory only — nothing here executes an operational action.
