Excerpt of the rules:
"Antenna near a marker beacon should be located on the continuation of the axial line of the runway at a distance of 850-1200 meters from the runway threshold of the approach and the displacement of less than ± 75 m away from the centreline of the runway.
The antenna far-marker beacon should be located on the continuation of the center line of the runway at a distance of 4000 ± 200 meters from the runway threshold of the approach and the displacement of not more than 75 meters away from the centreline of the runway."
But the long-range (outer) NDB in the North is located at 6 km ...
Fog and stress added to the confusion ...
"The correct rate of descent" in this case is somewhat different from "traditional", "victim of automatism".
That's all the "false glide path", favourite local trolls ...
Descending to the correct height, waiting for the signal passing inner NDB.
And it is not coming ...

It is in this place (2 km) opposite side of the ravine.
Stress, hair standing on their necks - you cannot change the laws of physics ...
At a distance of 1700 meters go lower still in disarray.
Hear the cries of the dispatcher.
Finally, everyone understands. There is still 1500m to the threshold ...
Well, about this point begins the diagram by the distinguished Aml ...
