Possible issue with payload calculations in the ME

[Lau]

Hi,

I have norrowed the best I could the weights & DIs for each individual station, there could be a mistake that I have not managed to find after countless cross-checkings since the process is not user friendly in the ME. The problem seems limited to this SEAD config since my CAP config was not affected.

The reason I'm doing this is to help with mission planning and the study of NATOPS perf for the F4E. That being said, basic numbers should add properly on the jet for an accurate simulation.

Thanks,

Lau

 

Edit 1 : Finally found an error that further reduces the discrepancy from 2776lbs to 1229lbs, getting closer. Pls let me know if you spot any other mistake that I could have done. These type of information's could be made available to the virtual pilots with the module upon release, after all these are the numbers used by the sim to calculate performance which could greatly help with mission planning and immersion.

Now this number is now getting very close to the 1128lbs which is the number used by HB for the weight of the external hard outer inner pylons and the four AERO 3B AIM9 launchers, which you can remove to withness how the weapon load goes in to negative values in the ME. This is due to the choice of HB to base the ZFW on an aircraft ready for war instead of a clean aircraft (31374lbs vs 32502lbs, the delta being 1128lbs). Now my question is did HB made a mistake by adding two times this number? With a bit of luck that could be an easy fix, unless the numbers that I am using are incorrect in which case, I would love that HB publish a full list of weights and Drag Indexes to help out with mission planning. Thank you

Edit 2: Out of curiosity, I have just recalculated my CAP config and reach to the same conclusion than my "edit 1", this time being even closer with 1120lbs discrepancy with the ME. This is now getting very much in line with an error from HB with the 1128lbs weight as explained in the "Edit 1". Thought I add this information since initially I stated that my CAP config was not affected.

Edit 3: Spotted a typo error naming the LAU-34A with LAU-117 but using the correct weight and drag for the LAU-34A on station 2, so my conclusions remain. I still updated the spreadsheet to avoid any confusion.
