and potentially even the taxi industry.

The growth of these unmanned aerial craft presents new opportunities for the aerospace industry,

but with more and more of them popping up, are they safe to crowd our skies?

I'm here at the Dubai Air show, where several of the latest drones are on display.

This here is the Aura 100 UAV.

UAV stands for unmanned aerial vehicle.

The company behind this drone are in the UAE to promote its capabilities and find customers.

We have already finalized all the test flights, and we have a few samples,

which are actually ready and flying.

I can say that we are ready for production now.

But the Aura 100 faces stiff competition, with drones from all over the world on display here in Dubai.

We've been flooded with opportunities here

from the defense sector and the government sector, to oil and gas.

The response has been really good.

Jason Braverman is here with his Canadian- built drone, which he says is ideal

for monitoring pipelines and carrying out surveillance.

If you look at the world, this is really the center of oil and gas,

and this region has very particular security issues.

The drone industry is expected to be worth $100 billion globally by 2020,

with military applications making up the bulk of market at $70 billion.

Consumer drones are expected to hit $17 billion,

while businesses and civil governments make up the last $13 billion.

Drone use is expected to grow in all of these three segments,

as production costs decrease and the technology behind drones advances.

For consumers, this could mean heading to a park and flying a miniature drone

with a camera for that perfect photo.

Commercial drones are used in sectors like transport, agriculture, construction or disaster relief.

In the aviation industry for example,

planes can now be inspected for safety by using cameras mounted on drones.

And in the military, the application of drones has allowed armed forces to spy,

increase their situational awareness, gain tactical advantages on the battlefield and even shoot at targets.

Controlling a drone of this type can be done in one of two ways.

Most are remote controlled, but some can self-fly using onboard flight sensors

and navigation systems like GPS to follow digital flight plans.

Amazon is developing Prime Air for autonomous, pilotless deliveries,

while Project Wing is Alphabet's version of the technology.

In 2019, DHL partnered with Chinese UAV maker Ehang to create a customized route for deliveries.

Ehang's new drone, the Falcon, was specifically designed to

overcome complicated road conditions and congestion.

U.S. drone startup Natilus wants to take unmanned delivery even further.

It recently completed tests for an unmanned aircraft prototype

that can carry cargo long distance over the sea.

There's only two ways to ship goods.

There's of course by ocean freight, which is very slow but inexpensive, and of course air freight.

We were always wondering if there was a solution that is something in the middle.

The plan is to reduce air freight costs by inventing a futuristic cargo drone

that would be 17 times faster than a cargo ship but half the price of using a Boeing 747.

The prototype is 30 feet in wingspan and weighs about 2,200 pounds.

The first product is a 3.4 metric ton freighter meant for feeder operation express service delivery

with companies such as FedEx and UPS and other worldwide ones.

And first flight is scheduled in two years.

Frankfurt Airport and drone maker Volocopter are exploring the potential

for an electric air-taxi service that doesn't require a pilot.

The same vehicle was already used to fly above Singapore's Marina Bay in October this year.

That trip was piloted but the aim is full autonomy.

Airbus and Boeing also have their own “flying taxi” projects

that would eventually dispense with an onboard pilot.

Autonomous urban aircraft could become a $1.5 trillion industry by 2040.

That includes everything from delivery drones, flying taxis,

military unmanned aerial vehicles, and industrial worker drones.

Analysts don't see technology as a barrier, noting that battery capacity,

computing power and the rise of 5G technology are all rapidly converging.

But if tech isn't the issue, then what will stop drones crowding the skies?

What can stop them crashing into each other and tumbling to the ground?

This is a UAV Traffic Management system.

What this technology does is identify drones in the sky,

helping to avoid collisions with other aircraft, such as planes, helicopters or other drones.

Our goal is to help every drone that is flying broadcast their position so that another

aviator can receive that information and make a decision.

In the future, the technology will be clever enough where drones can talk to drones,

drones can talk to airplanes automatically, and they can automatically avoid.

The system has been designed to work in tandem with a camera mounted on a radar

which can spot drones heading towards a restricted area.

So the camera's kind of integrated with that drone radar to follow this thing as it's being picked up.

Is it a bird? Is it a plane? What is it? Okay it's a drone, great. Now is it a drone we know about,

or is it a rogue element that we need to take a different action on?

By one estimate, there will be more than 76,000 drones operating in the U.K.'s skies by 2030.

The majority will be deployed for defense, health and education in the public realm and

agriculture, mining and energy firms in the private sector.

But as with other disruptive technologies, public policy often has to play catch-up.

Safety remains the main concern of regulators.

Analysts say that current U.S. Federal Aviation Authority restrictions have been an obstacle

to the sector's commercial development.

They argue in order to unlock the technology's potential, drones should be allowed to fly

above 400 feet, be allowed to fly out of the pilot's line of sight and be granted the

ability to self-pilot and soar over populated areas.

Drones have been with us for several years and their growth looks set to soar.

The benefits should include an increase in productivity, safety and even new jobs in the drone economy.

But how they fly, where they fly and what they are being used for are all challenges to be solved.

Thanks for watching! Let us know in the comments below which industry

you think is going to benefit most from the rise of the drones.
