On the Zeppelin NT pitch trimming is done via the relative fore/aft ballonet inflation rather than with the elevator trim.
On the Zeppelin NT pitch trimming is done via the relative inflation of the fore/aft ballonets rather than with the elevator trim. Shifting air between the ballonets moves the center of gravity.


* To trim towards nose heavy - set the fore ballonet valve for inflation and/or the aft for deflation.
* To trim towards nose heavy - set the fore ballonet valve for inflation and/or the aft for deflation.
* To trim towards tail heavy - set the aft ballonet valve for inflation and/or the fore for deflation.

If the airship is above <i>pressure height</i>, i.e. the altitude where the lifting gas occupies the entire volume of the envelope, the ballonets are empty and cannot be used for pitch trimming (and the simulated airship is likely to go badly out of trim). Ascending above pressure height also result in loss of lifting gas, beware of losing too much or you will be unable to maintain the envelope pressure when descending to the ground again.
