New FEAST test at july 2011 in Spain.
SDM was replaced by a brand new test: DART (Dynamic Air Radar T---).
There isn't any info on the internet about DART.
It had nothing to do with strips. It was a radar simulator. You had to change heading and flight levels to avoid conflicts (not local or opposite conflicts, but real crashes).
It's easier than SDM. Instructions are well explained and you have 3 tests to practice before real test.
