According to post 1346 the accident helicopter was higher and to the west of the position of the typical helicopter flying that route. Was this a slight error that in this case was fatal?
NTSB chair pointing out the horizontal position of the helicopter during last weeks testimony.
The altitude is still uncertain because of difference between jet and heli values and destruction of the heli altimeter. So work on that is continuing with a focus on other sources.
But note the 75 ft separation is a maximum. So if the heli was at 200ft then it was on the glide slope.
Another interesting point is that mixed heli and fixed wing is forbidden in the yellow zone (permanently), and ADSB mandatory in the red zone. With routes 4 and 6 cut.
