HI
I found an interesting discussion on calculation formulate in progress. I would like to contribute on the same.
Before we know what is C , K or other terms are. We need to know basics of CG shift and law of movement.
Each aircraft when manufactured needs to specify various dimension i.e. distances. So, a arbitrary point is fixed by the manufacturer from where all calculations will be written. This reference point is called Datum Point.
Thereafter so we are suspending a load of 1000 kg at a longitudnal distance from the datum point. The impact of this load needs to be studied. So, arm x wt = movement. This was all types of loads are computed for movement. Now the movement put together becomes so big a figure which is difficult to handle. As such, a figure is selected which will reduce the big size. This is called C constant for which we need to rely on the engineer who has freezed the formula. The index movement is poistive K constant say 50 or 100 is selected.
Trust it gives some information to your field of discussion.
