I don't know if you can measure that, the airplane would have to be flying perfectly level (to at least within 0.5%).

  0.5% is around a pound for a lot of people.. should be ok, isnt it?

    It's not the magnitude of the measurement, it's that if the airplane is descending at 1 degree when you measure, you'll get around 1% less weight than your actual mass. If the airplane is descending at 90 degrees, you weigh nothing.

      If the airplane descends at 90 degrees, I have a different problem :-)

        Eh just wait until it gets to one meter from the ground and jump off, a one-meter jump will be no problem.
