There are various roles for the Zeppelin NT; traditional roles have been aerial tourism purposes and for conducting passenger services. The hull surfaces of the aircraft have also been used for advertising purposes. The Zeppelin NT have also been used for observation platforms, such as for aerial photographers and by television commentators covering major events. Due to their capability for low-vibration flight for up to 24 hours at a time, ZLG considers the airships suitable for research missions for environmental observation, troposphere research and natural resource prospecting.
