With more than 1100 exhibitors from 60 nations, the bi-annually Dubai Airshow, hosted in November, is one of the most important aviation trade fairs in the world and has seen continual growth since it began in 1986. Two of Hamburg's core areas are particularly important in the Gulf Region: aircraft cabins, and maintenance and modification. The cluster, Hamburg Aviation, is representing the world's third-largest civil aviation site as part of the official German Pavilion.
