Hi Xercules, I don't think your kg. inches was invented in 97. I first came across them on the Chinook in 81. It took me a while to get my head round it particularly since the datum was way out in front.
I share your frustration with those who provided the AD RTS (I don't think we ever called it that!) when I looked after said document a few years after your time, there was certainly tables with both kgs and lbs in brackets in most of the Hercules chapters. Certainly the min and max dropping speeds at various aircraft weights to preserve the stall margins and suspended loads for parachutes.
Then someone suggested metricating the breaking strains of all the cord and wire we used. - It was not me! Honest.
