Trust questions, answered
Does TANGO certify documents as authentic?
No. TANGO extracts, compares and flags evidence. Authenticity, eligibility, airworthiness and regulatory acceptance remain decisions for qualified people and applicable authorities.
What does a confidence score mean?
It describes how reliably TANGO reads or reconciles a field from the available material. It is not a supplier rating or a legal conclusion.
Can teams change the completeness checklist?
Yes. Authorized users configure required evidence by workflow and material context, and TANGO records which checklist version ran.
What happens when files conflict?
TANGO cites both sources, creates an exception, withholds a final conclusion and routes the issue to the appropriate reviewer or supplier request.
Make the next evidence review easier to defend.
Create a controlled workspace and let TANGO structure the package before your team makes the decision.
