Jayteeto you see it only from the perspective of the Flight Crew. Just for a moment consider the relatives of the Pax. They might reasonably ask why the AC was less than 1 mile from the Mull, doing 170 knots Groundspeed below 500 feet heading straight at the mountain shrouded in fog. At this point the new TANS Waypoint was reselected by the crew. The new waypoint track was never acquired.
After that the AC began a climb but failed to clear the mountain, the final flight path onsistant with late visual acquisition of the terrain.
Those are the facts that we know. Post 431 was an inaccurate summary.
Agaricus Bisporus - I hear you five by five and agree. Some people seem unable to emotionally detach. The job that day was to transport passengers. When you read some posters they seem to have forgotten that. I also believe fighting in the wrong direction runs the risk of missing the obvious. In the case of the Mull, if they had WX Radar and used it, I doubt very much whether the event would have occurred.
Q. Do large Military UK helicopters now have Radar?
