Reduced from 5 to 3 miles for A320 behind 777 at Paris. Almost cut in half.
"Thanks to Recat EU, the distance between a 777 and an A320 has dropped to 3 nm from 5. A controller may also want to introduce a bit more space between two aircraft and insert a third one in between. In any case, the level of safety is unchanged."
