| ***What is  | The FAA has included the "Best Practices" advisory     |
| the FAA's   | material that was developed by an industry Working     |
| proposed    | Group in 1999 and 2000, which included participation   |
| requirement | by the FAA National Simulator Program (NSP). The       |
| or text?*** | material is also included in the 2^nd^ Edition of the  |
|             | ICAO 9625 document and JAR STD 1A, amendment 3.        |
|             | Although the material has been included in Sections 8  |
|             | through 16 of the proposal, it has been re-organized   |
|             | and re-written to the extent that the clarity of the   |
|             | material has been reduced and it is difficult to       |
|             | compare the different qualification standards. This is |
|             | especially the case in Section 9.                      |
+-------------+--------------------------------------------------------+
| ***What     | The material in the proposal appears to compromise     |
| about this  | industry efforts to harmonize regulatory standards for |
| proposed    | the qualification of flight simulation training        |
| requirement | devices. Considerable industry time and expense has    |
| do we want  | been expended over many years to support the FAA and   |
| changed?*** | JAA to harmonize these standards. It is acknowledged   |
|             | that the format of Part 60 may not have readily        |
|             | allowed the incorporation of the "Best Practices"      |
|             | material. However, if the intent was to include the    |
|             | material without significant change to content, it     |
|             | should align closer to JAR STD 1A, Amendment 3, or     |
|             | ICAO 9625, 2^nd^ Edition.                              |

  ***Specific     Table of Contents for Appendix A (page 59607) and\
  section of the  Appendix B (page 59703)
  proposed

  concern.***     

  ***What is the  The titles for several sections in both Appendix A and
  FAA's proposed  Appendix B are the same, and contain the FSTD
  requirement or  abbreviation. For example, Section 8 in each Appendix is
  text?***        titled *"FSTD Use (Sec. 60.11)."*

  ***What about   We suggest revising the Section titles so that those in
  this proposed   Appendix A refer to ***[FFS]{.underline}*** and those in
  requirement do  Appendix B refer to ***FTD***. Accordingly, Section 8 in
  we want         Appendix A would be titled *"FFS Use (Sec. 60.11),"* and

  ***Why is the   This suggested change would enable specific, clear
  change          references to sections of the document and more
  justified?***   accurately describe the contents of each Appendix.
