The Federal Aviation Administration (FAA) has granted Amazon Prime Air permission to operate UAVs beyond visual line of sight (BVLOS). This allows Prime Air to expand its UAV delivery service to more customers and scale operations across the U.S.
Prime Air’s BVLOS operations rely on detect-and-avoid technology, which allows UAVs to autonomously navigate obstacles for safe flight operations. Amazon provided the FAA with detailed engineering data and conducted flight demonstrations, which included real-world scenarios involving planes and hot air balloons, to validate the system’s safety.
With this FAA approval, Prime Air will extend its delivery area in College Station, Texas, using its MK-27 UAV. The service will integrate into Amazon’s existing delivery network, with UAVs deploying from facilities adjacent to same-day delivery sites.
Prime Air received an Air Carrier Certificate in 2020. The recent BVLOS approval further extends its capabilities, allowing Amazon to access more densely populated areas. The UAVs aim to deliver packages within 30 minutes or less.
Many have heard about efforts by Amazon to use UAVs for home delivery of orders within hours. Unfortunately, Amazon’s UAV trials have yet to be transitioned to “production” across the United States. Its website states that UAV deliveries are only available in College Station, Texas, and Lockeford, California.
Walmart is also in a trial phase of getting its rapid UAV delivery system working; however, its same-day UAV delivery is only servicing customers in the Tampa, Orlando, Phoenix, and Dallas areas. Nevertheless, there are many other automated deliveries underway around the world for meals and product deliveries, especially in Asia.
One segment where UAV deliveries appear to have been successful for medical samples and medications, which are now being shipped regularly on time-sensitive routes by UAVs (and, of course, several trial deliveries of these items are still underway).
The EMED transport/courier service used extensively by the UK National Health Service took part in one of the most recent medical shipment trials — which recently wrapped up in UK — with more than 400 pathology samples being rapidly shipped by fixed-wing UAVs between two hospital sites.

The UAV used in the EMED trial was a tried and tested Swoop Aero Kookaburra III fixed-wing aircraft with a 3kg payload that flies at 330 ft in segregated airspace.
In the United States, OhioHealth aims to use a proven medical delivery system supplied by Zipline. Its plans for delivery UAVs include rapid shipments between Ohio medical facilities and prescription delivery to patients. By 2025, OhioHealth predicts that more than two million people in the Columbus area could be served by the Zipline delivery system.
OhioHealth plans to use Zipline’s Platform 2 delivery UAV — a fixed-wing carrier UAV with vertical take-off and landing (VTOL) capabilities able to autonomously hover and accurately lower a package-carrying “droid” into a tight delivery spot. The previous Zipline Platform 1 system drops packages by parachute, which requires a substantial area to receive deliveries. The “droid” has three directional fans that allow it to maneuver at the end of the tether to within six feet of the planned delivery point.
Over the last six years, Zipline has built up a whole fleet of Platform 1 aircraft and the complete infrastructure for its medical delivery operation in Rwanda.
In Rwanda, there was a need for different delivery methods to get medical supplies to hospitals, as communities are spread over large distances. Before bringing such a service to the United States, Zipline aimed to get a delivery service running, get experience, and de-bug and prove the system’s capabilities. Six years and half a million deliveries later, Zipline is now ready. For civil certification, the Federal Aviation Administration previously liked to see lots of evidence of established operational activity. Therefore, Zipline was fortunate to have six years of proven delivery activity in Rwanda when they looked to start up in the United States.

Zipline has also done everything needed to ensure the delivery process in Rwanda is as efficient as possible — from the order processing system, through packaging and loading into the UAV, a catapult launch system that accelerates the aircraft to climb-out speed, battery charging and exchange for each flight, autonomous navigation to the delivery point, parachute delivery at destination, autonomous return to base, and an automated capture system on arrival. As a result, it’s not unusual if a delivery can be dispatched within 90 seconds from receipt of an order.
The distances are large in Rwanda between where people are sick and where they can get help, and the necessary supplies may well be located elsewhere — at times, as much as 150 miles away. However, since Zipline deliveries became common, in-hospital maternal mortality rates have been reduced by 88% — quite an achievement. Each delivery that is dispatched really has the potential to save a life.
Now, Zipline has the potential to improve turn-round times for the health system in the United States. The company is ready to prove that the Platform 2 system makes very little noise because of specially designed propellers, that precise deliveries are possible, and it is even ready to take on regular parcel deliveries without being limited to only medical shipments.
Hopefully, some of the big retail organizations will be willing to watch, listen, trial and eventually bring the proven Zipline delivery system into their operations. There is much work to do to bring about regular UAV deliveries, but with a proven track record in Rwanda, the odds favor a successful outcome in the United States.
A2Z Drone Delivery, developer of commercial UAV delivery solutions, has launched its second generation RDST integrated cargo UAV, the RDST Longtail. The RDST Longtail features the company’s factory-integrated RDS2 drone winch, allowing payloads to be deposited safely from altitude so that spinning rotors are kept far from people and property.
The RDST Longtail serves as an off-the-shelf, ready-to-fly delivery UAV for last mile delivery. It can deliver or retrieve payloads up to 5 kg and over a distance of 11 km, making it suitable for various applications such as local parcel or food delivery, emergency medical deliveries, water sampling programs, offshore logistics, search and rescue operations and more.
The RDST Longtail continues the company’s focus on addressing consumer-protection concerns as the number of residential drone deliveries increases. By conducting deliveries from altitude, A2Z Drone Delivery’s solutions protect recipients from spinning UAV propellers, while mitigating privacy concerns of low-flying UAVs. Depositing payloads from altitude also keeps the UAV high above trees, power lines and buildings, enabling longer sight distances for missions requiring visual line of sight.
With the upgrades made to the RDST Longtail, A2Z Drone Delivery aims to democratize drone delivery for residential delivery and cases where operators need to quickly and efficiently deliver or retrieve payloads. For example, A2Z Drone Delivery platforms are in use delivering emergency defibrillators to first responders in the field, collecting water samples for analysis and delivering supplies in disaster relief efforts.
The UAV can also auto-release packages without the need for a recipient to be present at the delivery location. This is made possible by the all-new bag auto-release mechanism, allowing for easy pickups and auto-releasing of bags during deliveries.
Designed to meet FAA regulations, the RDST Longtail is remote ID compliant with a factory-integrated remote ID beacon. The Premium edition of the drone can fly in inclement weather and features a quick-release battery system for minimal downtime.
“Our prototype RDST Longtail has already logged 500 flight hours conducting daily residential parcel deliveries near our Ground Zero Test Facility outside Shanghai,” said Aaron Zhang, founder and CEO of A2Z Drone Delivery. “Many of the upgrades included in this second generation RDST have been made in response to customer feedback on capabilities they need to deploy for missions in inclement weather. The RDST Longtail is the flexible commercial delivery UAV for last-mile deliveries that will round out a logistics fleet.”

Two Walmart locations in Utah, one in Lindon and one in Herriman, are now providing UAV delivery for customers nearby. Walmart has UAV deliveries operated by DroneUp, Flytrex and Zipline at 36 stores in the United States.
For a $3.99 fee, customers within a mile of the stores can receive their groceries via UAVs. The two Walmart locations in Utah can deliver more than 120 times per day and each UAV can carry up to 10 pounds. The hubs for deliveries are in the parking lots of each Walmart location and are operated by Federal Aviation Administration-certified pilots.
Walmart is using UAV delivery in seven states, including Florida, Arizona, Texas, Utah, Virginia, North Carolina and Arkansas. The most common products delivered include ice cream, lemons, rotisserie chicken, Red Bull and paper towels, according to Walmart.
Walmart drone deliveries launched in October 2019 in Arkansas. In 2022, Walmart completed more than 6,000 deliveries across all 36 participating locations.
A2Z Drone Delivery LLC, developer of a patented tethered freefall drone delivery mechanism, has launched its RDSX commercial delivery UAV.
The company delivered the UAV in collaboration with a global logistics provider to deliver dual payloads per flight, helping drone service providers streamline deliveries while mitigating consumer concerns with residential drone delivery. The RDSX integrates A2Z Drone Delivery’s proprietary tethered freefall Rapid Delivery System capable of quickly and safely delivering payloads from altitudes as high as 150 feet. By keeping spinning rotors far from people and property, the RDSX helps mitigate consumer concerns with drone deliveries—such as the potential for property damage and intrusive rotor noise—and assuages some of the privacy concerns with low-flying unmanned aerial vehicles.
A2Z Drone Delivery will be showcasing the new RDSX at the Commercial UAV Expo (September 7-9, 2021 in Las Vegas, NV).
The RDSX is a flexible drone delivery platform capable of carrying dual payloads each weighing up to two kilograms on a round trip of up to 18 kilometers. Alternatively, it can be configured with a single tether to expand its range out to 30 kilometers. The controlled-freefall delivery method it employs allows UAV service providers to reduce time-on-station to a minimum by delivering the package to the ground in seconds and eliminating the need for the drone to touch down. By maintaining its altitude throughout the delivery, the RDSX keeps spinning rotors away from people and property, mitigating consumer concerns and enabling it to deposit payloads into areas congested by trees, wires, or other dangerous obstructions.
The integrated A2Z Drone Delivery app combines manual control system operations with an onboard computer and sensor array to manage the package’s controlled-freefall and gentle stop before the ground. With the package delivered, the RDSX’s Kevlar tether and auto-release mechanism releases the payload before being reeled back up for reuse.
A2Z Drone Delivery’s freefall delivery technology has previously been leveraged for residential drone delivery trials, deployment and retrieval of ground sensors for energy exploration, as well as for shore-to-ship port delivery. The technology is equally applicable for first responders delivering life-saving medicine, for search and rescue professionals quickly deploying equipment to remote areas, or for rapidly collecting samples throughout an expansive mining facility.
The RDSX leverages a proven UAV flight platform equipped with a pair of cameras allowing pilots to navigate beyond visual line of sight (BVLOS). Additionally, the system features an independent downward-facing LiDAR sensing system to stream continuous data to the onboard firmware which controls the payload’s rapid descent and allows the pilot to visually monitor payloads through flight and delivery. Featuring quick-swap bucket-style batteries to limit downtime between flights, the RDSX can operate in diverse conditions including temperatures ranging from -20 to 45 Celsius, in up to 95% humidity, and from elevations up to 4,800 feet. Additionally, the RDSX’s eight rotor arms, fitted with durable carbon fiber propellers, can fold away for easy transport of the drone.
With its patented delivery system, A2Z Drone Delivery, LLC is developing innovative solutions to enable safe, accurate and low-noise drone deliveries. Its flagship delivery system, the RDS1 (Rapid Delivery System) enables payload delivery and retrieval to locations where most UAVs are unable to land, and its RDSX is a commercial multi-payload delivery system designed to meet the needs of the growing drone delivery industry. Based in Los Angeles, A2Z Drone Delivery originated as a drone delivery project at Brown University in 2016.

Network Tool Helps Find Children
Microsoft and Esri Canada have developed the Child Search Network to enhance Canada’s national strategy for missing children. The network provides police services with a quick way to share information and collaborate with others, as well as with the general public, to find missing children faster and reunite them with their families. Police can put out information on a missing child via a website and smart-phone app. Members of the public can then offer tips by downloading the MCSC rescue app to register to receive alerts and share any information they may have regarding a missing child or youth. The tool helps meet the “gap of response” for high-risk cases of missing children that do not meet the strict criteria for the AMBER Alert.

S’more Delivery Options
Grocery chain Kroger and Drone Express have launched a pilot delivery program in Centerville, Ohio, filling orders in as quickly as 15 minutes. Orders are sent to the customer’s smartphone location, which could include sending picnic supplies to a park or sunscreen to a beach. As part of the project, Kroger is selling bundled products within the payload weight — about five pounds, such as a S’mores bundle with graham crackers, marshmallows and chocolate.
One of the largest Adélie penguin colonies in the world was surveyed with multiple UAVs in March. Survey time was reduced from three days (with a single drone manually piloted) to under three hours. The work was led by a team of experts from Stanford University, Point Blue Conservation Science and Conservation Metrics. UgCS software by SPH Engineering was used to develop a system to autonomously survey the penguins. Thousands of high-resolution images were taken on each survey. An artificial intelligence model by Conservation Metrics is under development that will automatically identify and count adult penguins and their chicks. Using UgCS with a Stanford-provided planning algorithm, the survey team efficiently photographed more than 300,000 breeding pairs at Cape Crozier, Antarctica. The surveys will contribute to large-scale assessments of penguin populations and breeding success, key metrics for monitoring the health of the Antarctic marine ecosystem.

Seeing Sinkholes with Satellites
Synspective Inc. is offering a sinkhole-detection prediction tool using satellite imagery analysis. Part of the company’s Land Displacement Monitoring service, an algorithm uses data science and machine learning to detect spatial and temporal variations. It can identify areas where sinkholes are likely to occur, areas where cave-ins have occurred, and areas where cave-ins are in progress. The input data is automatically updated, and the platform handles the processing and analysis of the complex satellite imagery.
UAVOS has successfully tested its cargo delivery UVH-170 unmanned helicopter. The trial aimed to validate a highly automated delivery flight from a vendor to a destination and back, across precisely pre-selected pathways.
The flight took 1.7 hours and covered a standoff distance of 62 miles (100 kilometers). Critical humanitarian aid weighing 17.6 lbs (8 kg) was delivered with neither the need to land nor the need for a ground-control station on the receiving side.
UAVOS’s UAS is equipped with line-of-sight data link (LOS) and satellite communication data link, which supports beyond visual line of sight (BVLOS) flights. Watch the cargo delivery UVH-170 UAV in action.
UVH-170 unmanned helicopter is designed for commercial operations and immediate air response, emergency relief under demanding conditions and tight timescales. The aircraft’s high standoff distance makes it well-suited to humanitarian and disaster relief applications.
The capabilities of the UVH-170 unmanned helicopter address many social (medical, pharmaceutical, remote communities, humanitarian aid, etc.) and economic (mining, oil and gas, courier, etc.) use-cases being requested by customers.
The solution is based on the gasoline engine UVH-170 unmanned helicopter. With a maximum take off weight of 99 lb (45 kg), and a payload of up to 22 lb (10 kg), the UVH-170 flies at an altitude of less than 8,200 ft (2,500 m) at maximum speed of 74 mph (120 kph).
“As we have seen during the trials, the customers can derive significant benefits from the use of the UVH-170 UAV,” said Aliaksei Stratsilatau, CEO and Lead Developer of UAVOS. “As a robust VTOL platform, the UVH-170 does not require any additional take off or recovery equipment, which makes it perfect for delivery to remote areas. Besides, the unmanned helicopter has demonstrated capability to operate in windy conditions with gusts more than 14 mps.”
UAVOS has offices in Hong Kong, the United States and Europe. Among UAVOS’ unmanned technologies is the high-altitude pseudo-satellite (HAPS) ApusDuo, multi-platform autopilot solution for converting manned vehicles of all types into unmanned, and unmanned aerial vehicles aimed to counteract systems of electronic warfare.
