The purpose of this revision is to add A321neo XLR equipped electrical rudder evaluation results, to address emphasis for the optional Autopilot (AP)/Traffic Alert and Collision Avoidance System (TCAS) function, to update the Appendix 3, Differences Tables to a more comprehensive content structure, and to update the Airbus Flightcrew Difference Requirement (DR) Table references. This revision converts this document to the new Flight Standardization Board Report (FSBR) format and complies with Section 508. Change bars are not included in this document because the entire report is revised and updated.
