Sundance Media Group Training with DMA and Yuneec

Sundance Media Group, LLC (SMG) has been busy this past quarter of 2017 and in an effort to share more of our experiences within the UAS industry, we will post articles more often.  No easy feat when we are more often in the field than in the office!

With most of the clients we train, there is a discussion of which platform is best to use.  Our answer, or rather question, is always the same:  “What is the purpose of UAV as a Tool within your business?”  Every UAV has a slightly different set of benefits and functions and it’s important to source the best equipment for the job at hand.

Early in August, there was an announcement that shook up the drone industry:  U.S. Army grounded its use of all drones and components made by Chinese manufacturer DJI citing concerns of “cyber vulnerabilities”.  As a result, several branches of the military have been investigating other UAV/UAS options.

Subsequent to having their original selection of UAV aircraft grounded for security breaches, the Defense Media Activity (DMA), reached out to SMG for consultation and to identify and train on aircraft that would meet the security directive issued by the Department of Defense.  The DMA is a component of the Department of Defense, in use of UAV for newsgathering, image capture, and field deployment.

Sundance Media Group recommended the Yuneec H520 and Typhoon H480 platforms, and the DMA immediately went about verifying the security statement provided by Yuneec USA regarding security of their platform.

From Yuneec’s Press Release from August 29, 2017:

“Yuneec’s customers recognize the importance of keeping data and images secure. The Yuneec data ecosystem empowers users and organizations to control their data at all times. Yuneec commercial sUAS do not collect and do not share telemetry or visual data to internal or external parties.”

On September 18, 2017, the Department of the Army, the sponsor of UAV programming, did certificate the Yuneec platform as a secure system that may be used for VFR DoD activity in accordance with existing COA’s. The impact of this certification is that the DoD’s DMA division has been able to immediately, securely replace their previous aircraft with an authorized platform that meets security requirements of the military.

According to leadership at the DMA, the Yuneec platform is the only “ready to fly”/ “off the shelf” product currently enjoying the Airworthiness certification for military use. While the new Yuneec H520 was not immediately available for the DMA to purchase, the DMA purchased several Yuneec Typhoon H’s.

Ultimately, the DMA contracted Sundance Media Group for training on their new Yuneec Typhoon H aircraft and with this DoD certification, SMG went to work in providing access to the certificated aircraft, creating a specific training manual and operational documentation for the DMA team.

The SMG team spent September 22 & 23 working with the DMA.  Our instructors, Luisa Winters and Douglas Spotted Eagle spent time going over standard safety practices with the Yuneec platform, the theory of night flight, and in the field working on practical operational use of the aircraft.  As beta testers of the Yuneec H520 platform, we also had the opportunity to demonstrate the new Yuneec H520 platform.

The DMA serves as a direct line of communication for news and information to U.S. forces worldwide. The agency presents news, information and entertainment on a variety of media platforms, including radio, television, internet, print media and emerging media technologies and Sundance Media Group is pleased to be a provider of services that not only meet the quality requirements of the Department of Defense, but also meeting the security requirements set forth by the Department of Defense.

The DMA also had their team film our training days for the creation of a DoD video showcasing how the DMA will be using these sUAS as a media tool.  Once that commercial is finalized, we will be sure to share the link out as well.

Educate.  Mitigate.  Aviate.  Empower your Aerial Workflow.

Plan your UAV Flight for Inspiring Eclipse photos!

2017 brings an opportunity of a total solar eclipse, a rare and exciting event. In recent times, the only place to view a full eclipse has been unpractical as being in remote areas or on the ocean have been the only viewpoints of quality. This year is much different!

cation in the USA is in the central corridor, but that doesn’t mean you won’t be able to see the eclipse in your area.   Learn more about the eclipse, its path, and what to expect from here. Sundance Media Group will be in Hopkinsville, Kentucky where there will be 2 minutes and 40 seconds of totality where the day will become almost as dark as night!

Capturing the sun with the moon overlaid will not be very practical with a drone. Simply put, a very small lens system with a wide angle (as most drones offer) will record only a tiny dot in the sky, and this is why long, telephoto lenses are required for proper direct capture of the eclipse.

However, the shadow of the moon passing over the earth is as dramatic as the eclipse itself, and a drone is ideal for this sort of image capture. Still images, time lapse images, or video can all be very exciting when captured from altitude.

Capturing the movement of the moon shadow over the earth will be very dramatic, and quite easy to capture with most any drone. We recommend the Yuneec Tornado, Typhoon H, or Q500 with the CGO‐series cameras.

To capture the eclipse properly, an ND filter is required. If capturing over water, an ND64 is recommended. If capturing over land, an ND16 will suffice. PolarPro and Freewell both manufacture ND filters for use on the CGO3+ camera.

The Neutral Density (ND) filter will slow down the camera’s shutter, allowing for smooth movement of the shadow, while also reducing the dynamic range, providing for clearer contrast and deeper color.

A wide open area is preferable. Being as high on a hill or other elevation with an unobstructed view is also extremely desireable. Altitude is the best way to capture the dramatic movement of the shadow.

With regulations preventing altitudes of over 400’, larger areas and hilltops are very important for the best recording of the experience. The extremely wide‐angle of the CGO3+ camera system will help capture a broader perspective, giving the shadow a very dramatic flair as it moves across the curvature of the earth.

The key to ensuring you capture the images you want is PLANNING your flight.  Safety is paramount as it is likely there will be many curious eclipse observers. You will want to ensure that where you are flying is legal and safe. Here are a few planning tips:

■   Ensure your UAV, controller and camera current on software/firmware updates

■   Scout the area you plan on flying; Check the airspace you plan to fly.

  • File a NOTAM, or “Notice To Airmen.” Dependent on the desired airspace, hobby users can electronically request ownership of a particular area above them at an altitude of higher than 400’. Requesting a NOTAM costs nothing, and is a good safety measure, particularly in areas where helicopters and fixed wing aircraft may be flying.

■     Pre-Plan the steps of your flight to ensure you capture your footage!

  • Practice the angles!
  • Between today and the eclipse, fly the drone to high elevations/altitudes to find the best camera angle at the best times of day for your eclipse view.

Take note of the sun’s location, proximate objects in the foreground, and identify (and write down) the best camera angle that shows more earth than sky. Keep only the horizon in the upper portion of the frame during this time.

Plan on allowing the drone to hover with no movement. The eclipse shadow will move quickly; approximately 2 minutes of totality in the central areas of the US; being prepared is important.

What you DO NOT want to do is spend an entire eclipse event messing around with your settings, or viewing it entirely through your remote/ground station. PRACTICE these angles so that you are able to naturally observe the phenomenon of the eclipse with your eyes (covered by protective eyewear, of course).

Although the small Yuneec Breeze is not recommended for high altitude flight, if you’re in an area where a hilltop and few obstructions exist, the Breeze may also be used. While there are no filters available for the Breeze, Neutral Density gel is available at any theatrical supply, and may be taped in place over the camera lens during this rare, exciting event.

Take caution to not point the camera lens of any camera system directly at the sun without proper MD filtration. It is very likely the intensity of the sun will burn the imager hardware of the camera, permanently damaging it.  Eclipse sunglasses are recommended as well. Here are are a few more eclipse safety tips to know about.

Above all else, practice standard UAV flight safety techniques. Avoid flying over persons, property, or animals, stay within required altitude limits, and keep a watchful eye on the drone during the 2 minutes of the total eclipse.

As we mentioned, SMG will be in Hopkinsville, KY to experience the “path of totality”. If you are in the area, be sure to register with the area organizers and drop by to say “hi”!

Fly Safe and capture some inspiring images! Be sure to drop by our Facebook page and share with us!

WITNESS TO HISTORY

1908 was a big year for the world; the automobile found its way to the masses through the invention of the assembly line, created by Henry Ford. Not only did the mass-production line bring affordable prices, it also created the middle class. up

We’re in much the same birthspace; UAV/Drones are just beginning to grow into toddler-hood and millions of individuals (88% male, by some polls) are rapidly acquiring the skills and technology required to foster and grow this new industry.

Some view drones as mere toys, sideshows for businesses and leisure users.

Nothing could be further from accurate.

Drones (Some hate the word, yet it has rapidly become accepted in non-military circles) are being used in many industries already. Oil fields, solar fields, search and rescue, law enforcement, fire control, delivery of life-saving or retail goods, terrain mapping, agriculture, artists, wildlife management, mining, land management, fishing, cable/telecommunications inspection, real estate, and so many other industries are already using aerial technology. There are even underwater drones to inspect hulls of boats, ships, docks, etc.

What many may not immediately realize is the growth industry behind drones. Manufacturers aside, there are parts providers, technicians, sales people, support people, pilots, operators, and vendors of services. Colleges all across the globe are scrambling to develop programs similar to those that Humber College in Toronto, Ontario have had for a while now. Open source software drives commercially-focused drones such as those from 3DRobotics company, and computer-aided design plays a role in developing commercial custom drones.

Just as the automobile delivered the middle class to America and other parts of the world, the drone/UAV industry is poised to continue that weave in modern society whether in medicine, delivery, cinematography, transportation, or whatever else may come forward.

Whether it’s designing a custom solution for corporate or commercial work, or small-format cinematography, my team and I are here to assist you in taking full advantage of the shift in world progress.  We are committed to providing the most up-to-date information, advice, technology development, and resources to assuring our clients are presented with the most cost-effective, performance-balanced product possible.

Why *I* Don’t Catch my Drone

Catching a Drone

Recently I was asked “When do you choose to catch your drone vs landing your drone?

Catching a drone in midflight seems to be a badge of honor amongst some drone pilots and the reasoning behind it is baffling. It’s “so easy to do” there are even videos that teach drone operators how to catch their drone.

They have a number of arguments in favor of doing so.

I don’t want to risk my UAV hitting the ground.” “Dirt gets into the props when it’s taking off or landing.” “It looks really cool to people watching, and it shows I’m a pro when I catch my drone.”

On Facebook I once made a comment regarding the safety aspect of drone-catching and was promptly rebuffed with “If you can’t catch your drone, you don’t know how to fly” was the leading theme in the long string of derisive commentary that followed. I *can* catch my drone, just as I *can* play tag with an angry bull in a corral (and have done so).

A previous article entitled “Understanding Turbulence,” discusses how rotors and lee-winds can unpredictably affect UAV/drone flight. A human body is an obstacle to wind and the body is capable of diverting rotor wash or create a sink space. While being able to catch a drone mid-flight is certainly ego-supportive, it simply is unsafe for oneself and bystanders.

Symbol-ErrorWARNING, BLOODY IMAGES TO FOLLOW BELOW!

 

OK, YOU’VE BEEN WARNED

Here are a few injuries from around the web, demonstrating a varying degree of injuries by small UAV propellers. Some propellers are nylon-encased plastic. Others are carbon-fiber (CF). CF props are the most dangerous of all as they have no give, and are very sharp on the edges, providing for faster flight and more precise control.

Small drone injury

This is a relatively small cut from a prop, incurred while catching a drone mid-flight. An arrogant UAV operator commented “He didn’t know how to fly.” Perhaps the injured person knows how to fly; an unpredictable wind caught his vehicle and caused it to tilt?

A drone selfie and catch went wrong when the props fell into the sinkcreated by a body obstructing air.

DroneSelfie

Some people simply don’t learn the first time. There are those that count these scars as “badges of honor.” One might call them scarlet letters of stupidity. This person has experience in cutting himself.

Larger drone injury

With a drone loosely in hand and the motors spinning down,the drone may fall away from or towards the body, catching a bicep or forearm.

Pre-stitch cut

This is a similar injury. The injured man was holding his drone by the landing skids and it “pulled away and then towards him” as the quadcopter attempted to self-balance. Nine stitches later, he regretted catching and holding the vehicle. At least the CF blades made for neat and clean slices.

Drone Stitches

Having a flying Cuisinart at arms-length or less simply isn’t a good idea for a variety of reasons. At arms-length is entirely too close to the face and neck.

A reporter for the Brooklyn Daily was struck by a drone, cutting her nose and chin.

ReporterCut

Ultimately, the crew at Mythbusters (they love UAV/Drones and use them in production of their show) did a segment on the potential lethality of drones. Perhaps a bit extreme, one cannot miss their point.

Latin pop-star Enrique Eglasias likely has lost significant sensitivity in his hand due to attempting to catch a UAV during a concert performance. I have little doubt that some UAV operator is reading this blog thinking “That guy is stupid” while justifying why he/she catches their UAV.

Eglesias

I don’t catch my drone because I lack the skill to do so; like most people proficient with a UAV, I can put it precisely where I want it to land.

I don’t catch my drone because I’m averse to injury of myself and others. Safety always precludes “looking cool” or even saving a small cost of operation.

It may look cool to catch a drone and it may even reduce the risk of ingesting dust or dirt particles into a motor, thereby shortening the motor’s life. Perhaps think of it this way; A new motor may cost as much as $50.00. That’s a mere fraction of the cost of a trip to the emergency room and likely significantly less costly than an insurance deductible.

Happy flying!

UNDERSTANDING TURBULENCE for sUAS

UNDERSTANDING TURBULENCE for sUAS

 

Image result for drone crash, buildingAs sUAV/drones become more and more popular, it seems that more and more of them are striking the sides of buildings, trees, or poles without the pilot understanding why.
“It was flying fine and all of a sudden it zipped up and into the side of the building.” “Everything was great until the drone had a mind of its own and flew straight to the ground.”
“The drone was flying over the trees and all of a sudden it spun around and dropped into the trees.”

Reading forum conversations around the internet suggests this is a common, yet unfortunate and avoidable experience.

First, let’s establish that flying in GPS mode may be ineffective when very close to a building. Signal may be lost, and this could explain a few of the building strikes.

However, far and away more likely in most instances the UAV was caught in a “rotor.” These are also known as up/down drafts, lee waves, or cross-winds, depending on which aviation discipline one adheres to. Needless to say, these phenomenon do exist, and play havoc with any sort of aerial activity whether it’s wingsuiting, parasailing, skydiving, model aircraft flight, swooping, small aircraft, and particularly light-weight multirotors.

Image result for wind turbulence map
THESE “WAVES” ARE INDICATORS FOR MANNED AVIATION AND CONSTRUCTION CREWS, YET THE PRINCIPLE IS
ONLY A MATTER OF SCALE.

Even when a manufacturer provides a statement of stability in “X” winds, this should not fool a pilot into thinking that the sUAS is turbulence-resistant. Given enough turbulence or infrequency of a wave, the UAV will become unstable.

It’s always better to be down here wishing we were up there, instead of being up there wishing we were down here.

The first rule is to set wind limits. Small quad-craft should stay on the ground at windspeeds of greater than 12mph/5.5 meters per second. Hexcopters should consider grounding themselves at 22mph/10meters per second. Of course, this figure may vary depending on your organizations policy and procedures manual, insurance requirements, or payload on the sUAS.

This video provides some demonstration of the cycle of the wave and how a gyro and accelerometer might cope with the cycles. Notice how all the aircraft are “cycling” in an attempt to maintain altitude and position, even as the waves of the wind rotate?

Truly, knowing about them is half the battle. Staying away from them is the rest of it. Failing the former, being able to manage the craft in turbulence is the next-best step.

A building blocks the wind on one side (windward side) and on the opposite side (leeward side) the wind will pay all sorts of havoc with any flying object. Winds will extend in distance up to four times the height of the obstacle, and two times the actual height.

Understanding Turbulence 2

40×4=160 feet. Therefore, for 160’ beyond the obstacle at ground level, your multirotor is at risk for catching either a down draft or an updraft.

Huh?

OK, say there is a building that is 40 feet in height, and you have a medium wind blowing. Gusting or steady, it makes no difference.

40×4=160 feet. Therefore, for 160’ beyond the obstacle at ground level, your multirotor is at risk for catching either a down draft or an updraft. Either way, the airframe/hull is not in clean air. In extremely high velocities (high winds) the ratio of obstacle/distance may be as great as 15X (of course, a UAS would likely not fly in these winds)!

In terms of height, depending on wind velocity, the UAV may have to climb as high as 80’ to find clean air above an obstacle. yet at 80′ AGL, the winds are likely entirely different as well, depending on the weather and other obstacles in the area.

The air goes over the obstacle and is “pulled” to the ground (downdraft), where it then “bounces” upward (updraft) and tries to resume its level flow.

These phenomena are entirely independent of  sinks,thermal rises, dust devils, and the like.

This also occurs in natural/unbuilt up areas. Trees, canyons, ridges, rock-lines; any large object will incur rotors. Avoid them. It’s virtually impossible to determine exactly where the down draft vs. the updraft may be occurring, and the location of these dirty winds will change with swind velocity.

Understanding-Turbulence-3

FLYING IN URBAN ENVIRONMENTS

When wind flows between buildings, the mass of the air/gas is compressed. This results in an increase in velocity. Think of squeezing hard on a tube of toothpaste, compressing the contents through the tiny hole in the end of the tube. This increases the speed/velocity at which the toothpaste squeezes out. The same thing occurs with moving air between buildings or other solid objects.

Depending on the wind speed, the increase may require as much as 4-10 times the distance before the winds return to “normal” velocity seen before the gap or corner.

Ground winds and winds “aloft” (true winds aloft are beyond the reach of most UAS operations) are rarely equal. Winds at 50′ are rarely the same as winds at ground level in an urban or suburban environment.  Even small berms in the ground can cause jarring turbulence (as shown above) that settle in the low areas. These urban “microclimates” can be very problematic for light weight UAS in required-precision environments.

Turbulence

Here is a more complex example of winds blowing at 22mph in an urban environment.

Complex Winds.JPG

complex winds 2

Compression of the flow due to building dynamics push the wind into more than 40mph in some areas. While the overall winds, and reported winds in the area suggest that the windspeed is perfectly acceptable for most commercial aircraft, turbulence and accelerated velocities within tight areas are far beyond the risk limits of most small UAS’.

Flying from warm sands to flying over water on a hot summer day may also create challenges to smooth and level flight.

DUST DEVILS

Dust devils are summertime phenomena that can be very dangerous to humans anywhere a UAS may be flying. If they happen in a city, there is usually ample evidence of their existence, as debris flies high in the “funnel.” These nasty actors can show up anywhere there is hot asphalt, sand, dirt, and if that mass of rapidly moving air connects with a cool surface, they can turn violent very quickly, slinging a sUAS far from its intended flight path.
Image result for dust devil Image result for dust devil

DUST DEVILS IN THE NEVADA DESERT CAN BE FRIGHTENING, ESPECIALLY WHEN TWO OR THREE COMBINE INTO ONE VORTEX.

If by chance a dust devil is seen climbing in the distance, prepare to bring the aircraft home and land. If the dust devil is anywhere near the vehicle, climb in altitude while moving in any direction away from the dust devil. They are usually very short-lived.

Image result for dust devilIMAGE COURTESY WASHINGTON POST

How do we avoid getting caught in turbulent air? The long answer is “experience.” Flying in these challenging spaces teaches us to find the lee, based on the behavior of the UAS, which will always be slightly latent to the wind.
The short answer is to study environments. Look at the wind indicators that might normally be missed.  Learn to read the environment; it’s not hard once one begins to look for the details around buildings, trees, brush, monuments, chimneys, and other ground obstacles.

Two standard practices that may save pilots from troubles;

  • Always use a windmeter/anemometer, and check the winds frequently in midday flights.
  • Have a corporate or personal policy of a hard-deck/stop speed.  This eliminates wishy-washy/should I/shouldn’t I decisions in the field.  Our cap for teaching students with a Hexcopter/Yuneec Typhoon H is 16mph. If a gust crosses 16, we immediately stop, and wait it out to determine the wind trendline.

Another practice (although not standard) is to put a 5′ stream of crepe’ paper on a stick at eye level or so. This WDI, or Wind Direction Indicator, will immediately demonstrate changes in windspeed or direction, both clues that the weather may be rapidly shifting.

Determine distances from obstacles as accurately as possible prior to flight in order to best understand where the rotors will occur.  Doing so goes a long way to maintaining control and safety when the drone is in flight. With a bit of experience, one rarely needs to worry about obstacle turbulence.

Happy flights!
