The aviation industry's biggest players are gathering in Dubai to strike deals and show off tech like the world's biggest passenger plane and electric flight. Here's what to expect.

The show will offer a close look at some of the most iconic planes in the sky today. Airbus' huge jet, the A380, will have one of its last hurrahs.

The largest passenger plane in the world, the Airbus A380, is dubbed the superjumbo. Airbus is stopping production of the plane after 2021.

It can hold 800 passengers.

A Boeing 787-9 Dreamliner will take flight as part of the show, while a Boeing 777-300ER, the world's largest twin-engine jetliner, will be shown by Emirates.

The 787-9 Dreamliner is the middle variant of three: the 787-8 is smaller and the 787-10 is larger.

Airbus will also bring some of its flagship planes, like the A330 Neo and A320 Neo.

Airbus will also show off other passenger jets like the A350-900 and the A220-300.

Smaller plane makers like Embraer, De Havilland, and Dassault will also show off their jets, as will defense companies like Lockheed Martin, which makes the F-35.

And smaller jets will be on display too, like Honda's private jet, which starts at $5 million.

The elite version of the jet can hold seven people and, unusually, has engines mounted over the wings to create a quieter cabin and more fuel efficiency.

The show will be filled with flying displays, including from the aerobatic demonstration section of the French Air Force.

The French Air Force "Patrouille de France" is performing, as well as the UAE's Al Fursan, its aerobatics display team, and UK-based civilian display team The Blades.

The show will feature the world's largest defense companies show their wares. Boeing will display military products like its CH-47F Chinook Helicopter, used by the US Army.

Airbus will display some of its defense products, like the C295 twin-turboprop transport aircraft.

The US Department of Defense will show off fighter jets and transport aircraft, including its F-22 Raptor.

Its aircraft on display include the E-2D Advanced Hawkeye, the F-15E Strike Eagle, and the A10 Thunderbolt.

There will also be the C130J Super Hercules, a four-engine supply plane.

The UK's Royal Air Force will bring along a Eurofighter Typhoon, which was designed by a host of European companies, including Airbus and BAE Systems.

The show has a focus on helicopters as well, including Russian Helicopters showing its new Mi-38 helicopter abroad for the first time.

Airbus Helicopters will show its H225, a helicopter tailored for police in Kuwait.

The show is a good chance to show groundbreaking technologies. The 2019 show includes prototype electric plane engines which will be used in the world's first electric air race in 2020.

Air Race E, together with Airbus, is holding the race in 2020, billing it as the "world's first all-electric airplane race." It will have teams from Europe and North America.

Event organizers say: "Air Race E will see electric airplanes race directly against each other on a tight 5km circuit just 10m above the ground and at speeds faster than any land-based motorsport."

The industry will be watching closely for deals between aircraft makers and airlines, militaries, and leasing companies. The last Dubai Air Show, in 2017, saw some of the largest deals in history.

Here are some of the major deals that we've seen at the show in previous years:

• In 2017, one US private equity firm placed an order for almost $50 billion worth of Airbus jets.
• Also in 2017, Boeing received one of the biggest-ever orders for single-aisle jets, worth $27 billion.
• $37.2 billion worth of deals were struck the 2015 show.

Just how big this year's deals are and what the aviation companies reveal, remains to be seen.
