Pilot/Plane issues: 1st person horizontal alignment (Battlefield 5)

Hey guys 🙂 

When playing as a pilot in BF5 and bringing the plane‘s nose downwards in order to shoot some bullets/rockets at enemies (infantry):

The game automatically slightly pulls up the nose of the plane which is veeery annoying and makes it harder to attack.

How can I deactivate this? So annoying...

This happens in 1st person view only.

thanks in advance
