However, the UGIB route requires EXTENSIVE changes in speed, altitude and manoeuvring to get to the starting point of 6N 93.788E.
The ending point and final straight line route segment proposed in the UGIB paper are based on the satellite data and fuel modelling. That final route segment is NOT dependent on the preceding flight path. The preceding flight path was only included to show there is at least one solution that could link the initial flight path (ie the radar observations) with the final route segment derived from the satellite data. It was not proposed as the ONLY solution that could do so.
