Inheritance Logic:

If new position attributes are added, the new rules are added to the corresponding Aircraft configuration rules.

If the existing position attributes are modified, the modified values are inherited to the corresponding Aircraft configuration rules.

In case of deletion of existing position attributes, the system deletes the intermixing rules and ETOPS twin position rules from the corresponding Aircraft configuration rules. If the interchangeable rules are getting deleted, the system deletes the records corresponding to the deleted interchangeable part in Intermixing rule, ETOPS Twin position rule and Permitted Serial #s from the Aircraft configuration.
