Except at half power directed away from the air. Quoteddirectly from the article:
"We were not aware that the power of the antennas in the United States have been doubled compared to what's going on elsewhere. We were not aware that the antenna themselves have been put into a vertical position rather than a slight slanting position, which then taken together compromise not only the radio altimeter systems but the flight control systems on the fly by wire aircraft."
