- Classify what each display is actually showing, distinguish repeated data from independent evidence and choose a safe response when the navigation picture conflicts.
- Interpret GNSS geometry, integrity and datum information without converting a precise display or receiver status into a guaranteed position bound.
- Audit every route leg, turn and cross-track corridor at useful scales and close a route that depends on hidden, stale or unverified data.
