Live coverage recordairindex.io/elip/coverage/cor_lax_dtla
Live / unsealed analysis. This report renders the current canonical ELIP coverage from live AirIndex data and is verifiable against the coverage record above and the published methodology. It is not a sealed, provenance-anchored artifact. Coverage is geometry over a reconciled inventory; it does not certify that any individual site is operationally usable for a given aircraft — that requires the site’s RiskIndex assessment and, for the full physical state, a Ground Truth field capture.
