Came up on a problem with the new burn with the charge changing when going into FFE, when it shouldn't. Got this from LSEC:
"Here is the Log for the Msn I was talking about. If you scroll down the log you can see right before FFE the computer changed the charge from 5 to 6. Then the student" had to change it back to charge 5."
Good day all,
I have investigated the problem reported and found there is a problem with IFCCS' auto-charge selection mode. Normally, IFCCS will select the "Optimal" charge which is the charge that can achieve the largest gun-to-target range within 85% of its max range. When new guns are set to fire such as is the case when going to FFE, IFCCS will reselect a charge but will try to keep the original charge ("Previous then Optimal" mode). It should only change charge when a violation occurs such as max range is exceeded, a crest clearance or air corridor problem . In the scenario submitted by 11Fd, this is not the case. In this scenario, the range to target increases only by 250-300m but IFCCS changes the charge although the previous charge could accommodate another 1300m increase in range. The technical analysis is completed yet but it seems that IFCCS remains in "Optimal" mode instead of "Previous then Optimal" when it reselects a charge. I do not believe this problem will occur very often but the units should be made aware of it. A problem report has been raised and this will be corrected in the next version of IFCCS .
Workaround: If the problem arises, the user should go the User Charge Selection mode and force the charge back of its previous setting.
