Cross section of approach path

Using Google Earth I have constructed a cross section of the approach path by sampling the elevation every 15 seconds of arc longitude (268metres - I hope) along the extended line of the runway.

For the purpose of calculating the distance to the runway I have assumed that the runway alignment is exactly east-west and have ignored the latitude change. This will result in a very small error in the result. So small it can be ignored in my view since the runway alignment is so close to east-west.

I have not arranged facilities to post pictures and I am not sure what would be most useful to people anyway - so I have posted raw-ish data only.

I hope I have used the right airport - the one to the north of the city. Should have double checked frst 54 49'N - 32 02'E


Distance from touchdown (intersection of first taxiway) and Elevation (from sea level I guess) all in metres.

Sorry it looks a bit naff, but the pprune she does not accept the tabs (converts them to spaces
