Differences between the FIM MOPS and the Aircraft Control Model on GitHub

There are some discrepancies between the Aircraft Control Model code on GitHub and what is described in the FIM MOPS in Appendix H (and the paper referenced on GitHub called “Derivation of a Point-Mass Aircraft Model used for Fast-Time Simulation”):

• In the FIM MOPS section H.2.3 and in section 4.3 “Derivation of a Point-Mass Aircraft Model used for Fast-Time Simulation”, the condition is missing from the MOPS Aircraft Control Model that is provided on GitHub.
• The Energy Share Factor algorithm (Algorithm H.4) in the FIM MOPS section H.2.3 last Else statement is slightly different than what is in the Aircraft Control Model on GitHub and in section 4.3 “Derivation of a Point-Mass Aircraft Model used for Fast-Time Simulation” which is below.
else if(eV > Vthreshold)
ES F = 1.7
• There is a lot more code for the increased drag than what is described in Algorithm H.6 in Section H.2.3 in the FIM MOPS and in section 4.3 “Derivation of a Point-Mass Aircraft Model used for Fast-Time Simulation”.

These differences don't seem to be causing any major issues for testing. But the documentation should be updated to capture these in a future version. Thank you.

Start by comparing the Aircraft Control Model on GitHub with FIM MOPS Appendix H and the paper “Derivation of a Point-Mass Aircraft Model used for Fast-Time Simulation,” focusing on sections H.2.3 and H.6 and paper section 4.3. Document the missing condition, Energy Share Factor difference, and increased-drag details in the appropriate future documentation version; completion means these discrepancies are accurately captured.
