Chapter 18 of 23 · DMS · Document Control

Controlled documents withaudit trails a regulator believes.

Document control built for a regulator who will ask "who approved this, when, and what did it replace." Every revision is immutable, every approval is signed, every distribution is tracked, every reader has acknowledged.

The manual revises
The proven marshalling fix changes the ground operations manual. The revision carries the action that caused it, routes for approval, and every affected ramp lead acknowledges the change, on record.

Why it holds

Approval + supersession are tracked, not implied.

Operations Manuals, Safety Notices, regulatory PDFs and training materials live under one control regime. A revision is a new record linked to the previous; supersession is recorded as a fact, not assumed from a filename.

What it does

The capabilities, on one record.

Revision control

Immutable versions, signed approvals, full supersession chain.

Digital signatures

Approver chain with cryptographic signing. Exportable for audit.

Distribution matrix

Role-based distribution with acknowledgement tracking and expiry escalation.

Expiry & review alerts

Review dates fire as workflow events. No document ages out in silence.

The records it produces

Real records, one reference each.

Every record carries a stable reference and a source on every field. Nothing is silently overwritten, and the trail is the record.

Revisions are immutable records, not file renames

Approval chains are cryptographically signed

Distribution acknowledgement is a tracked record

Review due dates fire as workflow events

The gate

Documents change for a reason, on record.

A revision links to the action or decision that caused it, approval is workflow, and acknowledgement is tracked to the person. The current version is never in doubt.
