For the second time in less than a month, flights at a major London airport have been halted by drone activity.

On Monday evening, departures from Heathrow Airport were stopped for about an hour after a drone sighting nearby with the British military investigating the situation.

But at a time when the number of drones—hobbyist and commercial—will only increase, is there anything airports and governments can do to safeguard against delays, and, in the worst circumstances, fatal collisions?

Tiny drone, big threat

It's no secret that a collision between an airliner and a drone could be catastrophic. Even though it's small, these "mechanical geese from hell" pose big threats to a plane's exterior and its engines.

Yesterday's disruption at Heathrow has been minor compared to the holiday mess at Gatwick Airport,  which shut down after an airport security officer spotted two drones  flying over a perimeter road. Over 140,000 passengers had their flights  diverted or delayed.  Airport operations at Gatwick did not resume until  36 hours after the original incident.

Detect, identify and jam

Small drones are elusive. Despite 93 credible sightings by witnesses at Gatwick Airport, there was no good video of the drone  in action, and drones are just as difficult to spot on radar.

Radar to  spot and track aircraft is designed to filter out small, slow objects,  which were previously most likely to be birds, so special sensors are  needed for drones.

Maybe something more advanced than manually aimed bullets is needed.

The Phalanx CIWS fitted to U.S. warships is a computer-controlled, radar-guided cannon  with an awesome rate of fire.

Affectionately known as R2-D2 (and "the  Dalek" to UK Royal Navy crews), it spits out 70 20mm rounds a second and  can shoot down sea-skimming missiles at the last second before they  reach a ship. A modified version, C-RAM, defends U.S. bases from rockets and mortar rounds.

According to a report from Goldman Sachs released earlier this year, construction will be the biggest commercial  sector for drone use in the near future.

We saw a similar trend when we  examined DroneDeploy user data in our Commercial Drone Industry Trends report — construction was the fastest-growing industry for drone use.

For  many, this trend isn’t a surprise.

Current commercial and prosumer  drones can easily fly the area of a typical construction site and  provide timely and high-resolution maps and 3D models of site progress —  offering significant efficiency gains compared to traditional methods.

Drones at Brasfield & Gorrie

Brasfield & Gorrie began exploring the use of drones for inspection  several years ago, but when new FAA regulations were released, wanting  to ensure full compliance, they ceased operations until gaining their  commercial section 333 exemption in December 2015.

Today, drone  operations are housed in the Virtual Design and Construction (VDC)  group, a 24-person team dedicated to improving construction processes  through the use of Building Information Modeling.

Advice & best practices for drone use in construction

Have  you been thinking about incorporating drones into your construction  business? The Brasfield & Gorrie VDC team have some advice to share:

• Plan your mission first. No  two construction sites are the same, and neither are the hazards  involved. The worst thing you can do is arrive to a site without a  predetermined flight plan.
• Establish your goals. Know what you want to do with the data before you collect it, since  this will determine the level of detail needed for mission success.
• Ensure FAA compliance. Be willing to deny services if unsafe or uncompliant operation is being asked of your organization.
• Enlist the help of real pilots. UAS flight overlaps with actual aviation. Brasfield & Gorrie  enlisted the support of a licensed pilot in order to establish  operational use of drones.
• Research before buying a UAS. Be alert and agile, as the technology is changing rapidly.

Faster data collection leads to Big ROI

Using  a drone to map the area allowed the VDC team to assess earthwork on the  site much more quickly than they could have done using traditional  methods, while also providing a higher degree of detail.

Whether they're swooping in to deliver packages or spotting victims in  disaster zones, swarms of flying robots could have a range of important  applications in the future, a new study found.

The robots can transition  from driving to flying without colliding with each other and could  offer benefits beyond the traditional flying-car concepts of sci-fi  lore, the study said.

The ability to both fly and walk is common in nature. For instance, many birds, insects and other animals can do both.

Robots with similar versatility

Robots with similar versatility could fly over impediments on the ground or drive under overhead obstacles.

But currently, robots that are good at one mode of transportation are usually bad at others,  study lead author Brandon Araki, a roboticist at the Massachusetts  Institute of Technology's Computer Science and Artificial Intelligence  Laboratory, and his colleagues said in their new study.

The roboticists developed algorithms

The roboticists developed algorithms that ensured the robots did not  collide with one another.

In tests in a miniature town made using  everyday materials such as pieces of fabric for roads and cardboard  boxes for buildings, all drones successfully navigated from a starting  point to an ending point on collision-free paths.

Adding the driving apparatus to each drone added weight and so slightly  reduced battery life, decreasing the maximum distances the drones could  fly by about 14 percent, the researchers said.

Still, the scientists  noted that driving remained more efficient than flying, offsetting the  relatively small loss in efficiency in flying due to the added weight.

In a move that’s been coming since a worrying earnings report late last year, Parrot has confirmed that its toy drones – the Mambo, Bebop and Swing – are being discontinued.

These drones are entry-level devices, mostly aimed at children as a cheap and accessible introduction to flying.

In an earnings report last year that came alongside another round of job cuts and staff restructuring, Parrot predicted further consumer losses and a significant contraction of its drone business in 2019.

“The actions taken are expected to reduce the annual loss to a sustainable level to continue responding to the market’s long-term potential,” said the company’s quarterly report.

The job cuts were expected to protect R&D investment with a view to stronger growth for Parrot’s various commercial drone companies. The plan was for most of those to be breaking even by the end of this year.

All eyes on the Anafi

The decision to step away from toys leaves the Anafi platform out on its own as Parrot’s main drone.

A spokesperson for the company confirmed to The Verge that “Parrot has stopped the production and development of any drone but the Anafi and its variations.”

Which makes a lot of sense. The Anafi has been designed to be an adaptable platform to suit both the consumer and enterprise markets, as we’ve seen with the launch of the Anafi thermal.

Rather than compete with DJI at every price point, the French manufacturer has decided to focus efforts on developing that platform and making it last.

Going against Parrot’s DNA

We spoke to Parrot CEO Henri Seydoux earlier this year about what drives him and how he goes about developing new products.

“When I ask myself what to do next, my point of view is ‘what is missing?’ What is feasible with actual technology but does not exist. And also I’m only interested in mainstream products. I am not a niche person. I try to develop things that anybody can use,” he said.

It’s clear the harsh realities of the consumer drone business are forcing Parrot in a direction Seydoux would prefer not to go. Sacrificing the company’s mass consumer appeal and shifting the focus towards its many enterprise interests makes solid business sense, but it’s not going to be as much fun.

If there’s one thing DJI is good at, it’s stuffing a ton of features and functionality into increasingly small drones — and nothing showcases this talent more than the Spark.

Despite the fact that the drone’s hull is roughly the size of a Twinkie, DJI somehow managed to cram in many of the same goodies you’d find under the hood of the Spark’s bigger, bulkier, and more expensive brothers.

Aside from its tiny and hyper-portable design, the Spark’s biggest feature is arguably its plethora of intelligent flying modes.

In addition to DJI’s standard stuff, the Spark sports a handful of brand-new modes, including Rocket, Dronie, Circle, and Helix (more on those in a moment). The drone also comes with gesture recognition abilities, which allow it to be operated without a smartphone or controller.

Spark is one of the hardiest drones we’ve ever encountered.

Another big addition is Spark’s obstacle avoidance system. While the ability to sense and avoid objects is usually a feature reserved for larger drones, DJI went ahead and built one into the hull of the Spark.

It’s not quite as robust as what you’ll find on the Phantom 4, or even the Mavic Pro, but it still serves its purpose, and helps you avoid crashes.

Oh, and let’s not forget about the camera. In addition to a 12-megapixel camera that shoots video in 1080p at 30 frames per second, the Spark also sports a two-axis gimbal. This lets it mechanically stabilize the camera and cancel out any jarring, shaky movements — resulting in smoother, better-looking footage. This also gives it a leg up on the competition; most selfie drones only feature single-axis mechanical stabilization.

A sturdy, colorful little drone

We’ve said it before and we’ll say it again: DJI makes some of the sturdiest, most well-designed drones in the game — and the Spark is no exception. It might actually be the toughest drone the company has ever produced.

With short arms, no legs, and a tucked away camera, there’s not much on this drone that’s likely to break in the event of a crash.

We wouldn’t trust it to survive a big plummet onto a hard surface, but if you’re flying over grass or carpeting, this little guy could probably drop two-dozen feet without suffering any serious damage.

The most likely items to break are the props, and those are cheap and easy to replace. All in all, Spark is one of the hardiest drones we’ve ever encountered, and the build quality is top notch.

The overall design isn’t particularly remarkable, though. Sure, it’s small and compact — but not so tiny that it’s a game-changer.

Truth be told, it’s not really much smaller than the competition. Yuneec’s Breeze drone is only slightly larger than the Spark, and drones like the Hover Camera Passport and ZeroTech Dobby are actually more compact and portable.

Don’t get us wrong — the Spark is extremely well designed and impressively small considering the tech it carries, but it’s definitely in the middle of the pack when it comes to portability.

There is one design element that really helps the Spark stand out from the crowd — both literally and figuratively. Unlike any other drone we’ve seen, this little bugger comes in a rainbow of different colors.

The swappable top plate is currently available in white, red, yellow, blue, and green — and we’re willing to bet other colors/patterns/designs are on the way. It’s not a groundbreaking addition, but it’s certainly nice to have color options.

Average fly time and recharge speed

DJI’s official specs say the Spark’s battery is good for 16 minutes of flight time with a full charge and optimal flying conditions.

Real-world performance is usually a different story — so we grabbed a stopwatch, sent the Spark into the air, and let it hover in place until it had to come down for an emergency landing. From takeoff to touchdown, the drone managed 14 minutes and 10 seconds of airtime.

During normal flight — while making full use of the drone’s motors, sensors, and processing power — we averaged about 13 minutes of flight time.

That’s not the full 16 minutes that DJI printed on the box, but it’s still decent — and puts the Spark well ahead of competitors like the Yuneec breeze (~11 minutes) and Hover camera Passport (~9 minutes).

That said, all these mini drones come with two batteries, which means the Spark can get about 26 minutes of flight time per outing, as compared to the Breeze’s 22 or the Passport’s 18. DJI has an edge when it comes to stamina.

The GoolRC T33 drone is a lightweight quad-copter selfie drone that is  designed and marketed to fit into the low-cost, fold-able drone segment.

Despite its small size and easy to swallow price tag the T33 comes  packed full of technology and advanced features that are commonly found  in the higher-end models.

All in all this brand gives the user more free  accessories; boasts more pros than cons; offers more bang for the buck  over its competitors; and has a ton of real reviews that seem to agree  that it is worth the cost.

Actual owners, professional reviewers and  critics alike have generally positive things to say for this particular  model of fold-able drone.

Pros of GoolRC T33

• Small capacity batteries
• Very short in-air time
• Relatively short range radio signal

The Verdict is In on the GoolRC T33

Now that consumers have purchased, explored, broken, fixed and put  the GoolRC T33 to the proving grounds the consensus seems to be that it  is a fair buy if you are in the market for a beginner level drone that  wouldn’t break the bank to replace.

It is the perfect vehicle for  children or those new to the dynamics of flight and wanting to learn to  become a better drone pilot.

The advanced tech features are enough to  satisfy the most savvy user but simple enough to be taken advantage of  by the push of a button.

The camera quality is good enough to send back  stunning images from endless new angles and with built-in Wi-Fi  capabilities your smart phone immediately receives the data and stores  it for later review. Don’t forget that the same smart phone can be  fitted to the controller and tilted to steer the drone and give it  various commands.

The GoolRC T33 is so well thought out that it has many  people wondering why other companies don’t take the same initiative and  create high tech yet affordable versions for every audience.

With a flight range of 5km which is considerably lesser than that of the  Mavic Pro, one may wonder why he should invest in this model especially  when it costs almost 2 times the price of Mavic.

Well, before we go  into that, here’s something you should take note of: recently, with the  release of Phantom 4 Pro,  the price of the present model has come down considerably, so it’s as  good a time as any to get your hand on the model if you are so inclined.

Pros

• 12 Mp stills with a resolution of 4000 X 3000
• 4K High Definition video (at 30 FPS)
• GLONASS and GPS dual positioning modules as well as dual IMUs and a dual compass module for greater reliability
• Flight time of 28 minutes
• Ability to handle heavy payload

Cons

• Longer charging time and shorter flight range than Mavic Pro

Features

A common consensus among enthusiasts is that the Phantom 3 ushered in  the birth of the camera drone. From that perspective, it’s fair to say  that the Phantom 4 is more of an evolved version of its predecessor — it  still carries most of the features found on the latter. Having said  that, though, it’s worth highlighting that DJI have introduced a number  of enhancements in key areas.

So here’s what you can expect to find on the Phantom 4:

1. Advanced optics: Although the camera remains pretty much the same as  that on the Phantom 3, it sports a host of upgrades in capability. The  refresh rate takes a leap from 60 to 120 frames per second. More  resolutions (3840 X 2160, and 2704 X 1520) are also provided alongside  the standard 4K option.
2. Active Camera Stabilization: This is an advanced 3-axis gimbal that  cancels out the camera’s vibrations and movements in flight.
3. OSS: Short for obstacle sensing system, this relies on 2  forward-facing optical sensors to help the drone detect obstacles and  navigate around them.
4. Automatic Flight Positioning System: Like the name suggests, this employs GPS technology to make the drone more user-friendly.

Performance

As a linear upgrade of the Phantom 3, the DJI Phantom 4 takes care of  most (if not all) of the former’s shortcomings. On the surface, it does  away with the old plastic body and replaces it with one made of a  magnesium alloy. This is informed not by the need to improve aesthetics,  but rather provide a more robust housing for the other improvements.

The Deer HS177 is a great drone for flying indoors due to its altitude hold. It will  hover steadily at a default height for ease of control, and this makes  it a great option for children or those new to flying drones.

This is a battle drone which means it can fight with infrared shots and is a blast for children and adults alike.

It also has a simple headless mode which ensures the front of the  drone will face the same direction as the pilot – another great feature  for beginners.

With its flight time of 9 minutes, emergency stop feature, 3 speed  modes, and a one-key start/ landing feature, the Deer HS177 drone is a  great drone to fly indoors with lots of control.

Pros

• Affordable
• Great control
• Hovers at default height
• Emergency stop feature
• Headless mode

Cons

• Batteries don’t last very long

How it compares to others

There is a lot of competition at this price point, but this model blows almost everything else out of the water. The reason being the ease of use and the amount of novice-friendly features it packs.

Most other drones at this price point are heavier and more cumbersome to control. They are also not as speedy or as reliable to fly. Many often do not feature the altitude hold function, which is absolutely essential for newbies and even expert pilots.
