Why are the engines of the Airbus A400M slightly tilted down? Picture: Youtube.

Firstly, are the engines really tilted down? I have tried to check another picture over the net, seems they are really tilted down slightly. But need confirmation from you experts, however.

Second, if it is true, what is the reason?
As Jeffrey points out in his comment to the question:


  In flight, they are probably horizontal.


When that plane is at cruise conditions, it will be in a very slightly nose-up pitch attitude. the thrust line from the props will then be in the direction of travel.
