I've heard that the A400 has a cross under problem for parachutists exiting the side doors. But I would think that could be easily resolved based on the fact that the C-17 had the same problem. The C-17 solved it with the right combination of airspeed, deck angle, flap setting, and air deflector angle. On the other hand, the A400's props may create a very different airflow around the A400 compared to the C-17's turbofans which may require more extreme measures to resolve. What have you heard concerning the A400's paratroop problem?
