About the Dubai Airshow
The biennial trade show brings together a who’s who of the regional and global aviation industry including Emirates, Etihad Airways, Qatar Airways, Boeing, and Airbus among others.
This year’s event i s set to be the largest, according to event organisers F&E Aerospace. There will be more than 1,000 exhibitors with up to 60,000 trade visitors expected.
F&E Aerospace Chief Executive Officer Sharief Fahmy said that Airshow has confirmed more 150 static aircraft displays and that the US military has confirmed fly-bys from a F22 and B1 aircraft.
The AirbusA400m military aircraft and the Boeing F/A -18E Super Hornet will be on display in the region for the first time.
Dubai-staple Emirates will display one of its Airbus A380s while Qatar Airways will have a 787 Dreamliner, Bombardier Global 5000, and a Airbus A330F on show.
Airlines will also be keen to show the changes to the interior of their fleets. Hybrid airlines flydubai and flynas (formerly nasair) will each have planes on hand displaying their respective new business classes.
Raja Azmi, flynas Chief Executive Officer said that the airline will also showcase its new airplane livery since rebranding from the nasair name.
Last month F&E Aerospace hosted the press at the new venue in Dubai World Central to showcase the new location that includes an exhibitor space the size of seven American football fields.
The move to the new location has been driven by Dubai’s evolving aviation sector driven by the growth of Emirates. Previously held at airport Expo near Dubai International the Airshow has moved to its new location because of the show’s growth.
Fahmy previously said that the new site meant the show was subject to less flying restrictions.
At its new location the Dubai Airshow has more than twice the available space with a total site size of 645,000 kilometres.
We definitely built a venue that attracts the right type of business to the Dubai airshow,” Fahmy said speaking about the new Dubai World Central location.
For the first time in the Middle East French aerospace company EADS will have an integrated presence alongside Airbus, Eurocopter, and Cassidian product static displays.
Along with the Emirates branded A380, Airbus will have a fill size A350 XWB cockpit mock-up at the show.
Airbus will also have several military aircraft on display.
American competitor Boeing will look to showcase its industry partnerships at this year's Airshow.
In service with UAE Armed Forces, Boeing will have a UAE Land Forces AH-64D Apache helicopter and a UAE Air Force C-17 Gobermaster III airlifter on show along with other military displays.
The Dubai Airshow is an industry-only event hosted from November 17-21 with tickets available at the door. F&E Aerospace is holding Skyview for the first time from November 18 – 21. The family-oriented Skyview is open to the general public giving visitors access to a 4,000 grandstand to watch aerial displays along with aircraft on the ground.
