Safe and easy to remember number for turning around a G-IV is 60 ft.
Unfactored landing distance is often well below 3000 ft when light, with figures in the 2700 ft range.
Ive seen one touch down and stop in less than 1800 ft. Getting airborne is somewhat of a different issue - but seems it went well in this case...
So can it be done? For sure.
Should it be done? Who can tell.
But reversing the entire length of the RWY....thats priceless.
