One more thing.
The 2nd pilot's remarks he knows of the ravine (10:30:45 Worst is that there is a hole there and fog showed up). Then he says that TAWS will be enough as long as Zietas (the navigator) enters something [introduces corrections]
After that they no longer discuss the issue which means that pilot and 2nd pilot might also be completely unaware of dealing with uncorected RA readings, possibly because they are shy of talking too much in presence of the Air Force general, busy trying to spot the earth, etc. The navigator was the LEAST experienced person there with some 30!!!! hours only on that equipment.
