thereby taking off overweight?
Don't sound so surprised. 200kgs, if it is 'overweight' is no more than the water left on the airframe after a shower of rain and if you are using standard weights on a charter/holiday flight you can pretty much guarantee you are underweight. Try and get the picture, 200kgs set against 60,000kgs is inconsiderable. If you are stuck for such a minuscule amount you must get the AFM out, not the quick reference handy cards, go through them chart by chart, temperature, slope, wind, pressure altitude etc. 200kgs will be a lot less than the thickness of a pencil.
