Hi,
Using this new, more accurately-scaled graphic, I re-drew the 3deg theoretical glideslope (blue line) which I assumed began about 300m into the runway, (normal touchdown point). I used another line to show the extended the runway elevation, (brown line).
PJ2 .. what is the white (or pale gray) straight line in the graphic (view from above)
Methink it's the line where must normally be the plane .. so the plane is not only too low but also left of the normal approach (and this already before struck trees) ?
