Uncrewed Aircraft Defined

Determining what is, and is not, an “aircraft” is so important because it determines whether it falls under the purview of the International Civil Aviation Organization (ICAO). If it does, then it is held to the same standard as traditional manned aircraft and must comply with all of the same requirements. 

Upon initial review, defining “uncrewed aircraft” seems to be intuitive and somewhat self-explanatory. However, with close examination and careful thought what is and is not “uncrewed” becomes less clear. For example, what if there is not a pilot in the aircraft but the aircraft is being flown by a person standing on the ground, using a remote control? Or must an “uncrewed” aircraft be one that is flown completely autonomously without any human input? 

The plain wording of Article 8 makes clear that the drafters intended “pilotless aircraft” to include aircraft that were remotely controlled, e.g., from the ground (via radio signals); thus, “pilotless aircraft” in the sense that Article 8 refers to an aircraft flown without a “pilot” of Article 32, which provides, “the pilot of every aircraft and the other members of the operating crew of every aircraft engaged in international navigation shall be provided with certificates of competency and licenses issued or rendered valid by the state in which the aircraft is registered”.

When is a uav – “pilotless”?

Defining “pilotless” is of great importance because, “no aircraft capable of being flown without a pilot shall be flown without a pilot over the territory of a Contracting State without special authorization by that state and in accordance with the terms of such authorization. Each contracting State undertakes to ensure that the flight of such aircraft without a pilot shall be so controlled as to obviate danger to the Civil aircraft.” 

The term “without a pilot” was later clarified to mean that an “aircraft which is intended to be operated with no pilot on board shall be further classified as unmanned,” Furthermore, “unmanned aircraft shall include remotely-piloted aircraft.” 

An aircraft is not required to be fully autonomous in order to be uncrewed. An aircraft that is controlled by a person is still “uncrewed”, so long as the person controlling the aircraft is not located within the aircraft. For example, a quad-copter- drone that is controlled remotely by a person on the ground is still an unmanned aircraft. RPA as “an [uncrewed] aircraft which is piloted from a remote pilot station”. 

all aircraft are subject to article 8

All uncrewed aircraft, whether remotely piloted, fully autonomous or combinations thereof, are subject to the provisions of Article 8 and inter alia the ICAO. Annex 7 makes it clear that remotely piloted aircraft (RPA), are simply one type of uncrewed aircraft, and all uncrewed pilotless aircraft, whether remotely piloted, fully autonomous, or combinations thereof, are subject to the provisions of Article 8 of the Chicago convention. Because RPAS are aircraft, ICAO is responsible for their international air travel. They are held to the ICAO standards.

Somewhat ironically, the Chicago Convention, which is considered to be the magna carta of civil aircraft, never actually defines the word “aircraft”. In 1967, in response to advancements in technology, ICAO re-defined “aircraft” as “any machine that can drive support in the atmosphere from the reactions of the are other than the reactions of the are against the Earth’s surface,” 

This change in the definition of “aircraft” came primarily as a response to the invention of “hovercraft”. A hovercraft is a machine that elevates itself off of the ground by pushing in downward to lift the vehicle off of the ground. Because a hovercraft creates lift by pushing air onto the ground it is not capable of “flying” more than a few inches in the air. 

The need for ICAO to redefine one of its most fundamental words, “aircraft” due to development of previously unforeseen technology—the hovercraft—is a perfect example of how quickly technology can change and how it can make prior norms outdated.

UAV In Agriculture

  1. BENEFITS OF DRONE USE IN AGRICULTURE

The use of unmanned aerial vehicles (UAVs or drones) in commercial farming is increasingly profitable. UAVs are used in pest control, monitor crop health, and create plans specific to a field. Drones help farmers get the most productivity from every square inch of a farm. When it comes to UAVs, your imagination can go pretty wild in terms of what is possible.

Drone technology can make farmers more efficient by helping them locate problem spots in vast fields or ranchlands. Increased efficiency could mean lower costs for consumers and less impact on the environment if farmers used fewer chemicals because drones showed them exactly where to spray. Drones can carry different tools, including high-resolution cameras, infrared sensors and thermal sensors. Ground-penetrating radar could even measure soil conditions.

Compared to traditional fixed wing aircraft, UAVs can fly lower, slower, and hover in place for extended periods of time, all of which enhance the precision, speed, and safety of pesticide application. In fact, studies suggest that pesticide application by a UAV could be up to five times faster than traditional fixed-wing aircraft.4

  1. Aerial Pesticide– The fact that UAVs can operate significantly closer to crops without causing damage, due in part to the lower thrust exerted by a sUAS relative to larger manned aircraft, reduces the concern for drift. 
  1. These benefits may also result in sUASs supplanting uses that have traditionally required hand-application for certain pesticides, reaping farmworker safety benefits currently addressed by the Worker Protection Standards.
  2. UAVs limit the risk of pesticides drifting to non-target areas, potentially poisoning non-resistant neighboring crops or agricultural workers. Drift can be caused by pesticides being released at improper altitudes, at inappropriate ambient temperatures, or with incorrect droplet sizes.28 EPA mandates specific applicator boom length and nozzle size to mitigate drift of certain pesticides. 
  1. Improve Crop Health- Agriculture drones can look at massive fields of crops to scout out where crops are too wet, too dry, too diseased or too infested with pests. 

Essentially, you make a drone map of your field and request the according analysis you need. And the goal of these analyses is to “scan” the field and determine the location and the percentage of problem areas.

There are, for example, analyses that can show you how to spot weed and diseases, identify pest-infested areas and even help you count plants and trees. Besides being drastically faster than traditional measures, drone data analyses offer exact numbers and percentages together with the precise location of healthy and problematic areas.

  1. Topography of Fields–  Allows farmers and agronomists to create an overview of their fields. To let them mark points of interest on their field (such as ponds, or barns) and calculate how large certain areas on their fields are.

    II. CHALLENGES TO IMPLEMENTING A UAV PROGRAM

  1. Old FAA Laws

There are rules and limitations, among others, on operational hours and require registration for UAVs. Some, but not all, of these limitations may be waived by the FAA Administrator. The technology of UASs is moving forward so rapidly that the laws and rules and regulations have been created, the regulations surrounding aerial pesticide application have not yet been updated to accommodate the specific benefits and limitations of UAS use. As a result, a patchwork of exemptions, waivers, and label modifications is currently required for a commercial entity to aerially apply pesticides via UAS.

  1. Burdensome Application Process

Many of the FAA regulations on aerial pesticide application have not been updated in almost half a century and fail to accommodate advancements in technology, especially UAVs.

However, companies can apply for waivers and exemptions from the FAA to use UAVs in a way that will benefit farming.

  1. Part 107 Waivers

The FAA Administrator has the authority to waive some of the limitations placed on UAV use, so long as the Administrator determines that “the proposed [sUAS] operation can safely be conducted under the terms of [the] waiver.” 

Anyone may request a waiver, but their request must include a “complete description of the proposed operation and justification that establishes that the operation can safely be conducted under the terms of the waiver.” 

The FAA says that it “will strive to review and issue decisions on waiver and authorization requests within 90 days”.

  1. Part 11 Exemptions

The FAA can exempt an individual from any FAA regulation by submitting a request for a Part 11 exemption. This pathway, however, is far more burdensome than the Part 107 waiver process as it requires publication in the Federal Register and opportunity for public comment. The FAA requires that the petition be submitted at least 120 days before the petitioner anticipates the exemption is required. Additionally, Part 11 exemptions are typically only valid for 2 years, as opposed to 4 years under a Part 107 waiver. The FAA does, however, provide guidance to individuals seeking a Part 11 exemption and a searchable database called the Automated Exemption System (AES) is accessible to the public.

  1. 333 Exemptions 

As of July 14, 2017, 18 individuals and companies have received a waiver of the § 107.35 limitation to multiple drone operations. DroneSeed’s success demonstrates that the FAA is open to the use of drones as pesticide applicators; however, the current complex approval process serves as a significant barrier to entry for potential competitors.

sUASs as a possibly safer and cheaper substitute for traditional fixed- wing or helicopter/rotocopter aerial applicators. In the meantime, a combination of Section 333 exemptions, Part 107 Waivers, Section 11 exemptions–depending on the size of the UAS–are a viable, albeit expensive and time-consuming, alternative to permit limited use and testing of sUASs for aerial pesticide application in the near future.

There are currently three exemption and waiver processes that a UAS operator would need to navigate to aerially dispense pesticides, depending on the type of UAS used. For UASs over 55 lbs., a Section 333 Exemption is required. This application is more open-ended, has fewer limitations, but is more expensive and takes longer to obtain. For sUASs, a Part 107 waiver may be used. These waivers are cheaper and faster to obtain, but are more limited in the restrictions that may be waived. Finally, Part 11 Exemptions permit relief from a vast array of FAA regulations; however, this process requires full notice and comment for each applicant and requires navigating significantly more regulations. An overview of each of these three processes follows next along with an example of a UAS aerial pesticide applicator that has successfully navigated these regulatory hurdles.

Recently, Yamaha received a Section 333 Exemption to use its UAS, the RMAX, in aerial pesticide application. Because the RMAX weighs in excess of 55 lbs., it is ineligible for the Section 107 sUAS rules and must use the Section 333 Exemption.
