One of the "faults" of the Tu-154 crew was entering the glideslope too late, too high, that resulted in excesive vertical and airspeed. Our friendly pilot has some problem with that. I already showed his suspicions about the Vy in my previous post. He started looking at how to determine the glideslope start from the published data and found some issues. There is a reason why the terrain contour does not extend beyond 8000m on pic 1. He extended the line and superimposed contour from Google Earth on pic 2 and discovered a discrepancy. Then when he calculated the altitude in relation to the RWY based on the real contour, he got something amazing (heavy blue line on pic. 3). He also realized that entering the glideslope was shifted on the graph by about 500m (pic 4).
That has other consequences. The beginning of glideslope is 9200m from the RWY. It took 28 seconds from there till OM. That is 9200 - 28x80 = about 7000m. The OM is supposed to be 6260m from RWY. He maintains that the plane was on a perfect 3deg 10' glideslope that was shifted to point not to the threshold of the RWY but at some field near the MM.
