Multi-Rotor or Single-Rotor: Which choice for your next project?

Although multi-rotor drones get most of the attention in the UAV world today, they’re not the only option for a flight project. But why would someone choose a multi-rotor over a single-rotor...or vice versa? Read on to learn the differences between the two, as well as their strengths and weaknesses. A key difference between the two, not surprisingly, is the number of rotors each offers. A multi-rotor aerial vehicle has several rotors that keep it airborne. In contrast, a single-rotor vehicle has one rotor plus a tail rotor to control its heading.  

Multi-Rotor

A multi-rotor is a good choice for operators who need to get a camera in the air for a short period of time. Multi-rotor drones are best for aerial photography and aerial cinematography. One of the advantages a multi-rotor is its high-degree of control over position and framing for aerial shots. However, a downside is speed and endurance limitations. Multi-rotor's high-level of stabilization comes with a constant need for fast and high-precision throttle changes. As such, Rules of aerodynamics dictate that the larger a rotor blade, the slower it spins, resulting in more efficiency. As such, a quad-copter is more efficient than an octo-copter but less efficient than a single-rotor. Flight time isn’t due to battery, but rather weight. There are options to help increase flight duration and payload capacity. A brushless motor for a heavy-lift electric multi-rotor is the best option for longer flight time and zero-vibration operations. If an operators wants the drone to stay airborne longer with a more substantial camera attached, a brushless motor for heavy-lift electric multi-rotor is your best option for longer flight time and zero-vibration operation.  

Single-Rotor

A single-rotor helicopter or other airborne tech project offers greater efficiency than a multi-rotor. Currently, single-rotor vehicles fill a small niche in the drone world. Single-rotors offer certain advantages. Remember the rules of aerodynamics? A single-rotor helicopter allows for longer blades to enable slower spinning and therefore expend less energy. Some applications require extended hovering, heavy payloads and/or long endurance. In these instances, a single-rotor may be the right option. However, single-rotor helis also have disadvantages. One knock is that they have significantly more vibration than a multi-rotor UAV. The larger blades also pose more danger. If a single-rotor UAV loses its overhead blade, the aircraft doesn't feature the fail safe of additional propellers. Whether flying a multi-rotor or a single-rotor, quality parts and components are vital for safety and performance.

FAA requests emergency fast-track of electronic drone authorization

It seems the Federal Aviation Administration (FAA) finally reached a breaking point with requests to access restricted airspace. Currently, it can take up to 90-days for an operator to get authorization to navigate controlled airspace. With more and more authorization requests pouring in, the logjam continues to get worse. As such, the speculation is that some operators decide not to wait and fly without authorization. This may explain the increase in the number of non-compliant operations, as reported by the FAA. It is estimated that there are over 250 drone-related safety reports each month.  

Access to restricted airspace

Under 14 CFR 107.41, “no person may operate a small unmanned aircraft in Class B, Class C, or Class D airspace or within the lateral boundaries of the surface area of Class E airspace designated for an airport unless that person has prior authorization from Air Traffic Control (ATC).” Since Part 107 launched, the FAA has received an extremely high volume of airspace authorization requests from UAS operations. From September 2016 to July 2017 the Agency received 20,566 authorization requests. Of these, the Agency processed 14,334. At any given time, there are up to 6,000 authorizations in the processing queue. Additionally, the number of requests continue to increase. The FAA expects the queue will exceed 25,000 pending authorizations within the next 6 months.  

Ongoing efforts by the FAA

The solution? Fast-track the electronic authorization of drone flights. The groundwork for this eventuality has been a work-in-progress for the FAA. The first step came when the FAA implemented Part 107 in August 2016. This year, the FAA – in collaboration with airport tower staff – developed and published a series of grids. These grids depict the maximum safe and permissible altitude for unmanned aircraft operations. The FAA published these maps online. The maps serve as the foundation for the Low Altitude Authorization and Notification Capability (LAANC) system. The goal is for LAANC to provide a quick and efficient response to airspace authorization requests.  

Real-time authorizations with LAANC?

When operational, the FAA believes LAANC will help the agency grant “near-real time" authorizations for the vast majority of operations. The FAA states that remote pilots certified under part 107, who submit requests that comport with the published limitations, can expect almost real-time, electronic approval. The system is also vital to the safety of National Airspace. The FAA expects LAANC to reduce “non-compliant” operations by at least 30 percent. Plus, once operational, it reduces distraction of controllers working in the Tower. The FAA’s recent request seeks to accelerate the implementation of LAANC, which was to take until the end of the year. “Due to the pressing safety consideration of reducing safety reports due to non-compliant UAS operations, the FAA cannot wait the normal 90 days of public comment,” the agency stated in the Federal Register notice Oct. 11. “Therefore, FAA is requesting Office of Management and Budget's (OMB) approval of this collection of information 7 days after publication of this Notice in the Federal Register. Upon OMB approval of its Emergency clearance request, FAA will follow the normal clearance procedures for the information collection associated with LAANC.”  

U.S. Border Patrol Announces sUAS Pilot Program

The steady advance of Small Unmanned Aircraft Systems (sUAS) into real-world environments, continues. In September, the U.S. Customs and Border Protection (CBP) announced  a new pilot program. The program, executed by the U.S. Border Patrol, evaluates the use of sUAS within the CPB operational environment. Tests sites, already identified, include three USBP sectors. The program kicks off within the Tucson sector with plans to expand to Rio Grande Valley and Swanton later this year.  

Eyes in the sky

Border Patrol agents will use the remotely piloted sUAS for reconnaissance, intelligence, surveillance, tracking, and acquisition capabilities. Their primary operational environment is in areas that are difficult to access or otherwise considered too high-risk for manned aircraft or CBP personnel on the ground. “We anticipate the sUAS program to be a valuable tool for Border Patrol’s highly trained law enforcement personnel in securing our borders and helping identify and intercept illicit activity along U.S. borders,” said Carla Provost, Acting Chief of the U.S. Border Patrol. “These aircraft will enable Border Patrol agents to surveil remote areas not easily accessible by other means, which is critical to our ability to secure the border," Provost said. "They will also be invaluable for humanitarian missions, aiding in locating individuals in need of medical assistance along inhospitable areas of the border.”  

Border Patrol sUAS program

The pilot program tests the operational effectiveness of three sUAS fixed-wing and rotorcraft: Puma, Raven and InstantEye Quadcopter. All of the sUAS share a few common features deemed vital for operations. Each is portable, easily fitting inside an SUV, highly maneuverable and deploy rapidly. The sUAS pilot features two rotations in each of the three identified sectors. The first rotations began in September 2017. The second starts in January 2018. The aim is to test both hot and cold weather capabilities of the sUAS. CPB will issue a final review late Spring 2018. The review is expected to also include future investment decisions and expansion of the program to other USBP Sectors.  

The End Game

The hope is that the rapid deployment of sUAS will help field agents do their job safely and effectively. The three sUAS models should deliver vital sensory and visual data to agents on the ground. Each model has a proven track record in military operations for surveillance and Force Protection missions. The sUAS program is fully compliant with all Federal Aviation Administration (FAA) regulations, policies and laws. USBP will operationally test the sUAS under an approved Memorandum of Agreement (MOA) between the FAA and USBP. The MOA in place maximizes risk avoidance to commercial and general aviation traffic in the National Airspace System. All sUAS are to operate under a 400-foot ceiling. In addition, USBP has an approved MOA with CBP’s Air and Marine Operations further addressing operational risk avoidance in day-to-day operations.

How drones are turning the tide on coastal monitoring

New and emerging technologies tend to enhance existing industries and services. In addition, emerging technologies also help create new industries and services. Unmanned aerial vehicles are one of the biggest trends due in part to their potential use across a range of service and industry applications. One such emerging application is coastline monitoring.  

Drones help fight the tide

There are many reasons why coastlines are under threat but climate change is widely seen as one of the biggest causes of beach erosion. A number of companies are starting to use drone technology for many coastal monitoring applications. The issue of protecting coastlines is a critical one in many countries across the globe. In the UK alone, over a million residential and commercial properties, as well as thousands of hectares in agricultural land lie within areas that are at the mercy of unpredictable changes. Undertaking coastal protection studies requires careful monitoring of any changes that occur. The most efficient solutions for arresting and reversing erosion of coastlines also requires an understanding of existing environmental factors and their effect on the affected beaches. Monitoring thousands of miles of coastline, though, is a tough ask especially in an era of dwindling financial resources. Effective solutions are gleaned through careful consideration of the above factors combined with any available historical knowledge and data. In effect, this is where emerging technologies like unmanned aerial vehicles come in.  

Coastal monitoring drones

Drones are quickly becoming an invaluable tool to both monitor and help maintain the health of coastlines around the world. UAVs provide many advantages for this application. One such advantage is a drone's ability to cover increasingly large distances in a single flight. Plus, when outfitted with the right equipment, drones can capture highly detailed images and footage. The data harvested on these mission can, in turn, help inform decision making. An additional advantage of using UAVs for coastline monitoring is the elimination of any human risk. For example, drones can quickly conduct an initial survey to assess damage after large storm events. UAVs can also monitor potentially dangerous situations, such as the stability of cliffs, from a safe distance. Additionally, UAVs can keep track of beach erosion by measuring land volume and capture changes in coastal vegetation states.  

Matching the drone to the environment

One company, QuestUAV, is demonstrating how new technologies can help tackle serious issues like environmental degradation. Their coastal monitoring work has helped local communities slowly reclaim lost beaches and coastlines. The harsh environment of the North Sea seemed a fitting place to test the feasibility and durability of drones for coastal monitoring. Wind speeds on the North-Eastern shores of the North Sea frequently reach up to 65 mph. Quest’s UAV platform features an airframe design with gimballed sensors and high spatial accuracy to ensure good data quality even in the difficult conditions. Plus, its use of Post Processing Kinematic (PPK) technology allows for detailed survey mapping. PPK technology allows the mapping of coastal areas with up to 2cm spatial accuracy without relying on Ground Control points. Given the difficulty in placing ground control points in landscapes such as coastal dunes and cliffs, PPK technology provides a faster and more economic way to achieve great results. Read about when and why our partner, Altavian, chooses to use PPK over RTK.  

Surveying remote and challenging environments

In addition to coastline monitoring, the company conducted geological rock and cliff surveys, monitored sea color changes, and inspected breakwaters. They've also monitored industrial applications based in remote environments such as mining sites and power stations. The company has kept track of the Northumberland Coast in the U.K. since 2008. In that time the area has suffered two major storms; one at the end of 2013 and another in the first month of 2017. In the aftermath of the most recent storms, QuestUAV deployed so as to immediately assess the damage. The information gathered is used in conjunction with historical data, satellite imagery and models created in 3-D to ensure an accurate compilation of current conditions.  

The future of coastal monitoring

Most experts agree that climate change is one of the biggest challenges to face mankind in recent memory. Beach erosion is one of the symptoms of the phenomenon. The use of drone technology can go a long way in the effort to help protect beaches and coasts around the world from being claimed by the sea.

Drone Insurance: what is it and do you need it?

Drone InsuranceWhen it comes to insuring personal possessions, many are tempted to decide against getting coverage if the law does not specifically require it. People are even more resistant if the cost to cover the item is higher than the cost to replace the item. That's just common sense, right? Maybe. Insurance can be an important part of planning for the unexpected, particularly if a business is involved. If you use drones in your organization, or are looking to do so, it makes sense to get insurance coverage for your air vehicles...just as you would for your terrestrial kind. There are several advantages to insuring your drone. For one, it enables you to recoup any losses due to mishap, crash or theft. And, even more importantly, drone insurance could potentially win you more clients. Many individuals simply won't work with a company that is not insured. But what is drone insurance and do you need it? And, if you're operating a drone-based business, what kind of insurance coverage do you need? Is it different from drone insurance? Read on to find out if drone insurance is the right move for you.  

Drone Insurance Coverage

Similar to other insurance policies, drone insurance provides coverage in the event of a mishap, accident or theft of the drone and any related equipment. This coverage can also include other ground-based and non-pilot crew in addition to drone operators. Drone insurance policies commonly comprise two parts; damage to the drone itself, and liability, which cover any damage and claims from third-parties. For additional peace of mind, your chosen insurer should also offer coverage for third party liability, personal injury, and premises liability. This provides insurance for any damage to your company’s buildings or those of a customer or private owner.  

Drone Insurance 101

The process of getting drone insurance is similar to securing coverage for a home or vehicle. Some companies may require additional information, such as: proof of training, maintenance logs, operating manuals, a record of parts or add-ons. Such documentation proves that you are operating your vehicle in a safe, conscientious manner. It also improves your chance of acquiring more favorable insurance rates. In terms of selecting coverage, it depends on a few factors including the primary way you employ your drone and the environments in which you operate. A drone used to take real estate photography may need different coverage than a drone used to inspect bridges. Identifying these potential hazards is a key to choosing the right amount of coverage.  

Drone Insurance Costs

When it comes to cost there are, of course, many variables. What type of drone a you're flying? How many drones do you need to cover? What are your potential operating liabilities? How much coverage do you need to protect yourself and your equipment? For example, a commercial-use policy for top end drones, such as the Yuneec Typhoon H or the DJI Phantom 4, costs between $600-$800 per year with coverage up to $1 million in liability. Another factor that influences cost is your flight experience. Of course, costs rise depending on the size of liability coverage you require. Each insurance company structures their policies differently. Some only cover single units while others are willing to insure multiple drones.  One option for fleet owners is a policy that offers coverage for both liability and physical damage using a pricing model for one UAV. As long as only one UAV is flown at a time, there is no additional cost to cover additional drones in the fleet.  

How to Get Drone Insurance

To insure your drone, simply get in touch with any of the insurance companies listed below. In addition to proof of any ongoing or completed drone pilot training, here’s what you’ll need to ensure that you get the best possible insurance policy for your business:
  • A minimum of 50 – 100 hours of piloting and flying UAVs
  • An FAA Drone pilot licence
  • Maintenance Logs
  • Type of Coverage; liability/ Hull
  • Details of Leases, or Proof of Ownership
  • Information pertaining to how the drone is used and operational environments
To ensure you get the best coverage for your dollar, you will need to shop around. Get quotes from a number of companies, compare costs and coverage and decide which one is right for you. A word of caution, it is possible to lose your coverage if any of the policy providers’ conditions are not met. These include but are not limited to: failure to log flight and maintenance data, operating a drone without proper identification details or serial numbers, and instances of unethical flying. For commercial operations based in the United States the following companies offer drone, UAV, and UAS insurance policies. Providers include Allianz, Avalon Risk Management, Aviation Insurance, Berkley Aviation, Skyvuse, UAV Protect, Verifly, Starr Aviation, and many others. There are many drone-specific insurers but others offer a broader range of insurance products.  

Filing Claims

Unfortunately, mishaps do occur and when that happens you'll need to file a claim. It's a good idea to review your policy and understand the claim process before an incident occurs. That way there are no surprises. Most often, the first step is to notify your insurance company as soon as possible. Depending on the incident, you may also need to notify local authorities. To expedite the entire process, cooperate with the insurance company. Provide any information needed quickly and efficiently. Though there are many advantages to drone insurance, particularly for commercial drone operators, ultimately the decision is up to you, the operator.

Steps to Take Before You Experience a Flyaway

Up, Up and Away!

Steps to Take Before You Experience a FlyawayA gust of wind. Interruption or loss of the control link. Pilot error. A dreaded flyaway. There are many ways to lose a drone. But when you think about the various hazards surrounding flight, outright loss may not come to mind. In fact, loss of a drone during flight is more common than you may think. Of course, today’s drones are more and more automated and most come equipped with GPS. But that doesn’t mean things can’t and don’t go wrong…because they do. In the event of a catastrophe, the odds of finding your drone improve based on the steps you take before such an event occurs.  

Register your drone with the manufacturer

There are two basic camps when it comes to registering product with the manufacturer: those who automatically do it and those who consider it a waste of time. Don’t neglect this step; there are many benefits to registering your drone. Some benefits include: proof of ownership, more efficient warranty services, product updates and recalls, and more. The minute you unpack your new vehicle, take the time to register it with the manufacturer. If your drone flies away, some helpful individual may contact the manufacturer and help reunite you with your drone.  

Register your drone with the FAA

As you know, as of December 21, 2015, the FAA requires all drones, model aircraft and other sUAS weighing between 0.55 and 55 pounds to be registered. You must register before your first flight. Registering your drone with the FAA is inexpensive, easy and it can save you from getting hefty fines.  

Update your drone’s GPS

If your drone has a GPS, power it up in a place that gives clear view of the sky and give the GPS time to update. Updates are automatically sent from the satellites. This step usually takes about 15 minutes but is well worth your time. Updated GPS helps ensure that in the event you need the drone to “return home” it has accurate positioning.  

Tag it with a tracker

GPS-based trackers are an inexpensive and popular option. GPS trackers provide accurate positioning details of a lost drone. In the event your drone flies away, information on the longitude and latitude of its location helps you zero in on, at the very least, your search area. There are several trackers available on the market today, each with their own pluses and minuses.  

Tag is with your number

It might not sound very tech savvy but putting your phone number on your drone is helpful. Consider this, if your drone flies off into the sunset, eventually, it comes crashing to the ground. There’s a chance some unsuspecting individual finds it, “Oh look, a lost drone!” If your phone number is taped somewhere on the drone, this good Samaritan may just give you a call. Low-tech but effective. Of course, it is always advisable for new flyers to grow their skills in open fields, away from obstructions and innocent bystanders. Keeping the drone within line of sight is also vital. Remember to fly with fully charged batteries and return home before the battery is completely drained. Read more helpful tips for first time drone operators.  

If you find a drone

If you happen to find a lost drone, there are a few steps you can take to help reunite the little buddy with his fretful owner. One option is to locate the serial number, call the manufacture and report it “found”. If the manufacturer is able to help, they’ll outline next steps. If the drone has a camera you can attempt to use the feed to communicate with the owner, which likely goes to their computer or mobile device. A shot of the phone number where the owner can contact you, is one suggestion. Place an ad on Craigslist. It might seem unlikely but an ad could help you find the rightful owner. And, of course, if the owner placed his number on the drone, simply give him or her a call.   In the event you experience a dreaded flyaway or simply lose your drone somewhere over the rainbow, consider the proactive steps listed above. Of course, there are no guarantees but the steps outlined may just help you get your drone back.
