It describes how to calculate values for tables 1503, 1504,1502, 1506 and 1507 that will result in accurate values for thrust vs altitude in FS.
The article is 19 pages in length and, in addition to the main body, it has two appendices. Appendix A contains a list and description of the tables, terms and equations used by FS when applying the corrected method of performance calculation to get actual values used in the aerodynamic calculations.
Appendix B contains a brief description of how to use the NASA applet EngineSim to verify FS flight test results.
I hope this article will help anyone who deals with .air files and I welcome discussion on its content.
