Low and flat approaches are msotly used for short field landings or grass strip approaches where the surface is suspect? Also, low and flat approaches presumes slow speed, dragging the aircraft in?
If that is so then I can think only that these pilots have not been taught to fly at airfields where there is sufficient runway to fly a visual 3' approach path; or that they have not the flexibility or training to adjust their flying technique to the conditions in which they find themselves and that could be serious bad news.
