A navigation performance based flight path deviation display assembly includes a display and a display processor capable of generating an image upon the display. The image includes at least one flight path scale comprising a reference point bounded by end markers extending in at least one of a lateral and vertical direction. The display also includes at least one moveable deviation pointer disposed on the flight path scales. Additionally, the image includes a representation of at least one extendable navigation error disposed on the flight path scale, and extending from at least one of the end markers toward the reference point based upon an actual navigation performance (ANP) and the RNP for the aircraft. The image may also include at least one moveable intersecting flight path pointer disposed on the flight path scales.

The method of claim 2 wherein: the disjunctive exclusion status of the base part provides that one or more features on the base part are suppressed; the exclusion status of the bridge node is updated to suppressed; and the exclusion status of dependent features on one or more derived parts is updated to suppressed. 8. The method of claim 2 wherein: the disjunctive exclusion status of the base part provides that one or more features on the base part are versioned; the exclusion status of the bridge node is updated to versioned; and the exclusion status of dependent features on one or more derived parts is updated to versioned. 9. The method of claim 2 wherein: a current exclusion status of the bridge node indicates that features on the base part were formerly suppressed, and the disjunctive exclusion status of the base part indicates that no features are currently suppressed; the exclusion status of the bridge node is updated to unsuppressed; it is determined that there are dependent features on derived parts whose primary exclusion status is suppressed and whose secondary exclusion status is combine-excluded; and the exclusion status of dependent features on one or more derived parts is updated to unsuppressed. 10. The system of claim 9 wherein the base part is a non-native part. 11. The system of claim 9 wherein the base part is a non-local part. 12. The system of claim 9 wherein the bridge node is created without modifying the base part. 13. The system of claim 9 wherein the determining comprises determining if the base part has been modified since the last time the host drawing was read. 14. The system of claim 9 wherein: the disjunctive exclusion status of the base part provides that one or more features on the base part are suppressed; the exclusion status of the bridge node is updated to suppressed; and the exclusion status of dependent features on one or more derived parts is updated to suppressed. 15. The system of claim 9 wherein: the disjunctive exclusion status of the base part provides that one or more features of the base part are versioned; the exclusion status of the bridge node is updated to versioned; and the exclusion status of dependent features on one or more derived parts is updated to versioned. 16. The system of claim 9 wherein: a current exclusion status of the bridge node indicates that features on the base part were formerly suppressed, and the disjunctive exclusion status of the base part indicates that no features are currently suppressed; the exclusion status of the bridge node is updated to unsuppressed; it is determined that there are dependent features on derived parts whose primary exclusion status is suppressed and whose secondary exclusion status is combine-excluded; and the exclusion status of dependent features on one or more derived parts is updated to unsuppressed. 17. The system of claim 9 wherein: a current exclusion status of the bridge node indicates that features on the base part were formerly versioned, and the disjunctive exclusion status of the base part indicates that no features are currently versioned; the exclusion status of the bridge node is updated to unsuppressed; it is determined that there are dependent features on derived parts whose primary exclusion status is versioned and whose secondary exclusion status is combine-excluded; and the exclusion status of dependent features on one or more derived parts is updated to unsuppressed. 18. The system of claim 9, the logic further comprising: determining if any databases represented by any bridge nodes have been unloaded from memory; and for all bridge nodes representing unloaded databases, suppressing all features connected to each bridge node via edge ordering connections, and their dependent features. 19. The method of claim 2 wherein: a current exclusion status of the bridge node indicates that features on the base part were formerly versioned, and the disjunctive exclusion status of the base part indicates that no features are currently versioned; the exclusion status of the bridge node is updated to unsuppressed; it is determined that there are dependent features on derived parts whose primary exclusion status is versioned and whose secondary exclusion status is combine-excluded; and the exclusion status of dependent features on one or more derived parts is updated to unsuppressed. 20.
