A. Petition Summary

Pursuant with Section 333 of the FAA Modernization and Reform Act of 2012, Pravia, 

LLC (Pravia) requests exemption from the following Federal Aviation Regulations that are found 

under Title 14 of the Code of Federal Regulations (CFR): Part 21 Subpart H, 45.23 (b), 91.7 (a), 

91.9 (b), 91.103, 91.109, 91.119, 91.121, 91.151 (a), 91.203 (a) (b), Part 91 Subpart E (91.401-

91.417). Pravia seeks expedited approval and exemption from the CFRs listed above in order to 

operate the eBee Ag Unmanned Aircraft System (UAS) for the purpose of providing high 

resolution aerial imagery to a domestic agricultural seed company. Operation of the eBee Ag by 

Pravia will follow strict operational limitations as outlined in this document and all

recommendations by the FAA. 

B. Background 

1. Pravia, LLC

Pravia is a scientific and technological services company located in Niceville, FL

that provides research, analysis, monitoring, and reporting of geographic data captured 

via remote sensing payloads aboard manned, fixed wing aircraft. Pravia’s two managing 

partners have been in the aviation industry for 17 plus years and have more than 8 years 

of combined Military UAS experience. Pravia’s UAS background makes it an ideal 

candidate to tackle the unique challenges associated with commercial UAS operations for 

precision agriculture. 

2. eBee Ag

The eBee Ag UAS is manufactured by SenseFly SA of Switzerland, and it 

includes a lightweight battery operated aircraft, ground control station, and associated 

data link equipment. The eBee Ag airframe is constructed of EPP foam and weighs only 
4

1.5 lbs. with a wingspan of 3.2 ft. The eBee Ag is powered by a lithium polymer battery

that drives an electric pusher propeller. It is hand launched, has maximum flight time of 

45 minutes, and operates at a cruising speed of 22 mph – 35 mph. The aircraft is linked to 

the ground control station via a 2.4 GHz USB radio modem with a maximum data link 

range of 1.6 NM. If onboard sensors detect a critical situation at any time (low battery, 

close proximity to the ground, weak data link signal, etc.) the eBee Ag will automatically 

initiate a preprogrammed safety procedure.

SenseFly manufactures a variant of the eBee Ag simply referred to as the eBee. 

The only difference between these two models is the camera suite that they carry. The 

airframe, ground control station, data link, and flight profile is identical between the eBee 

and eBee Ag. All referenced SenseFly documents in this petition will simply say eBee 

and will not specify eBee or eBee Ag. 

The eBee Ag has extensive flight experience and a history of operational success 

overseas. It has been approved for Visual Line of Sight (VLOS) operations in the UK, 

Switzerland, Australia, Canada, and Ireland and Extended VLOS operations in France. 

In the United States, the eBee Ag is being used for research by New Mexico State 
5

University’s Physical Science Laboratory UAS Test Center. NMSU is currently operating 

an eBee Ag under a Certificate of Authorization (COA) to develop safety of flight 

procedures for mapping industry projects such as open-pit mining and oil and gas 

operations. 

For additional information on the eBee Ag, reference Appendix B (eBee User 

Manual), Appendix C (eBee Inspection and Maintenance Requirements) and Appendix E 

(eBee Justification for Airworthiness and Safety Assessment) which specify 

manufacturing information, aircraft performance, operating limits, normal and emergency 

procedures, fail-safe features, and maintenance and inspection procedures.

C. Statutory Authority

1. FAA Modernization and Reform Act of 2012, Section 333

Section 333 (a) states that the FAA “shall determine if certain unmanned aircraft 

systems may operate safety in the national airspace system before completion of the plan 

and rulemaking required by Section 332”. Section 333 (b) then lists several factors that 

should be considered in determining which UAS’ would be eligible for expedited 

integration into the National Airspace System (NAS). Specifically UAS’ that “as a result 

of their size, weight, speed, operational capability, proximity to airports and populated 

areas, and operation within visual line of sight do not create a hazard to the users of the 

national airspace system or the public, or pose a threat to national security”. If a UAS 

meets the criteria laid forth in Section 333 (b), Section 333 (c) then gives the FAA the 

authority to decide if an airworthiness certification as specified by Title 49 United States 

Code, Section 44704 is even required for operation. Section 333 (c) specifically states 

that the FAA can determine “whether a certificate of waiver, certificate of authorization, 
6

or airworthiness certification under section 44704 of Title 49, United States Code, is 

required for the operation of unmanned aircraft systems”. Thus, the FAA has the ability 

to allow a UAS that meets the criteria put forth in Section 333 (b) to operate within the 

NAS without an airworthiness certification as long as the UAS does not pose any hazard 

or threat to the NAS, public, and national security.

2. How Pravia meets the criteria laid forth in Section 333

Below are the criteria laid forth in Section 333 (b) and a detailed description of 

how Pravia meets each of these criteria. 

a. Size, Weight, and Speed

The eBee Ag’s foam airframe weighs 1.5 lbs., has a 3.2 ft. wingspan and 

operates at cruising speeds of 22 mph – 35 mph. This small, lightweight aircraft 

that operates at relatively slow speeds will poses little to no hazard to people or 

structures on the ground, thus making it an exponentially safer alternative to 

manned, fixed wing aircraft for aerial imaging. 

b. Operational Capability

The primary function of the eBee Ag is to provide aerial imagery using 

one of four interchangeable geo-reference still cameras. High resolution data 

generated from these cameras offer a wide range of applications through analysis, 

such as biomass estimation, yield monitoring, leaf area indexing, and overall crop 

health. This information then helps companies maximize crop yields, which is of 

great benefit to the economy and the public.

The eBee Ag is hand launched on-site, requiring no runway for take-off 

and landing and no transit to and from the site. Once airborne, the eBee Ag will 
7

fly at an altitude of 400 ft. AGL or less over the designated agricultural plot. Prior 

to flight, the Pilot in Command (PIC) sets a designated flight area and flight 

parameters to ensure that the eBee Ag will remain within the confines of the 

approved site and not exceed a maximum altitude 400 ft. AGL. If onboard sensors 

detect a critical issue at any time, such as a low battery state or loss of GPS signal,

the eBee Ag will immediately execute preprogrammed safety procedures

(Reference Appendix E). The eBee Ag’s small operational footprint and built-in 

safety protocol provide a much safer alternative for aerial imaging and would 

pose a minimal hazard to the NAS or public. 

c. Proximity to Airports/Populated Areas

The eBee Ag will only operate over agricultural plots for the purpose of 

collecting aerial imagery. There are 10 sites over which the eBee Ag will be 

flown (Reference C.3.b.). All sites are owned and operated by a domestic 

agricultural seed company, which has already granted approval to Pravia to 

conduct eBee Ag flights. There are a few small office and maintenance buildings 

located amongst the agricultural plots and Pravia will ensure all eBee Ag 

operations avoid overflight of these structures. In addition there are no 

commercial airports within 5 NM and no general aviation airports within 3 NM of 

any of the sites. The eBee Ag will also operate at an altitude of 400 ft. AGL or 

less, and as a result will be laterally de-conflicted from manned aircraft 

operations. By operating at low altitudes over agricultural plots the eBee Ag will 

pose no threat to individuals or structures on the ground and will remain well 

clear of any and all air traffic. 
8

d. Visual Line of Sight (VLOS)

The eBee Ag will be flown in accordance with day Visual Flight Rules 

(VFR) and only in Visual Meteorological Conditions (VMC) during day-light 

hours. The eBee Ag will operate within 1 NM and VLOS of the PIC (and the 

Safety Observer positioned next to the PIC) at an altitude 400 ft. AGL or less. The 

Safety Observer will be responsible for ensuring that the eBee Ag remains within 

VLOS at all times and will also assist in spotting potential hazards. 

3. Other Relevant Factors 

a. Operational Limitations

Pravia has established the following operational limitations for eBee Ag 

flights over designated sites. 

o eBee Ag flights are only permitted over designated sites

o The eBee Ag will operate at or below 400 ft. AGL

o The eBee Ag will operate within 1 NM and within VLOS of the PIC 

and Safety Observer

o The Safety Observer will be located next to the PIC and will ensure 

the aircraft remains within VLOS and assist in spotting potential 

hazards

o The eBee Ag will operate in accordance with Day Visual Flight Rules 

and only in Visual Meteorological Conditions during daylight hours

o The duration of each eBee Ag Flight shall not exceed 45 minutes
9

o All take-off and landings will occur on-site in accordance with the 

SenseFly eBee User Manual (Reference Appendix B)

o eBee Ag flights will avoid direct overflight of any office or 

maintenance buildings located on-site

o All employees working on-site will be thoroughly briefed on eBee Ag 

operations prior to operations commencing

o eBee Ag operations will be conducted by commercially certified pilots 

who have completed SenseFly’s eBee Training (Reference 

Appendix D)

o eBee Ag flights will be cancelled in the event that any aircraft or 

ground control station equipment is inoperative or not fully functional 

o If the PIC or Safety Observer spot a potential hazard, such as a 

manned aircraft within close proximity to the designated flight area, 

the PIC will immediately land the eBee Ag and operations will only 

resume after the hazard is clear of the area

o All eBee Ag maintenance will be accomplished in accordance with the 

SenseFly eBee Inspection and Maintenance Requirements (Reference 

Appendix C)

o Only one eBee Ag will be airborne at any given time for each 

designated sites

o The PIC will file a NOTAM for eBee Ag flights at each site, 

providing at a minimum radial/DME, radius, and a date/time group
10

Pravia will be bound by these limitations for commercial flights after FAA 

approval of the exemptions laid forth in this petition. Pravia will also follow any 

guidance from the FAA in accordance with Sec 333 (c) which states that after 

determining if UAS meets the criteria for safe operation that the FAA “shall [also] 

establish requirements for the safe operation of the” UAS in the NAS.

b. Sites

There are 10 current sites that are owned and operated by a domestic 

agricultural seed company where eBee Ag operations would be conducted. This 

company has already granted approval to Pravia to conduct UAS operations at 

these locations. These sites are agricultural plots where crops are grown and 

monitored by scientist in an effort to increase crop efficiency and yield. A few 

small office and maintenance buildings can be found at several of these sites and 

Pravia will ensure all eBee Ag operations avoid overflight of these structures. In 

addition to this there are no commercial airports within 5 NM and no general 

aviation airports within 3 NM of these sites (Reference Appendix A for additional 

site information)

As precision agricultural continues to grow there is the potential for 

additional sites that would require eBee Ag operations for aerial imagery

collection. In addition to seeking approval to operate the eBee Ag at these 10 

current sites, Pravia seeks approval to operate at future sites that meet the

following criteria: 1) site is owned and operated by the domestic seed company, 

2) site consists of agricultural plots, 3) no commercial airports are within 5 NM of 

the site, and 4) no general aviation airports are within 3 NM of the site. Pravia 

will also comply with any additional requirements or restrictions the FAA may 

have for eBee Ag operations at these future sites.

2. Specific Sections of 14 CFR from which Pravia Seeks Exemption

Below are the sections from which Pravia seeks exemption, with specifics on the 

extent of relief sought, reason for relief, and why exemption would not adversely affect 

safety.

a. Part 21 Subpart H – Airworthiness Certification

Part 21 Subpart H establishes the requirements for the issuance of an 

airworthiness certificate. Pravia seeks complete exemption from Part 21 Subpart 
12

H pursuant with Section 333, which authorizes the FAA to exempt a UAS from 

the requirements of an airworthiness certificate based on consideration of the 

following: size, weigh, speed, operational capability, proximity to airports and 

populated areas, and operation within VLOS. 

An equal level of safety will be achieved with the operational limitations 

established in this document (Reference B.3.a) for all Pravia eBee Ag flights. 

Specifically that all flights will occur within VLOS of the PIC and Safety 

Observe, at an altitude of 400 ft. AGL or less, and only over designated

agricultural plots. As a result the eBee Ag can safely operate without creating a 

hazard to any other aircraft, people, or structures on the ground. The combination 

of the eBee Ag’s safe operational history in Europe and the United States and 

small, lightweight airframe, in conjunction with Pravia’s pilot requirements and 

operating limitations result in a safer alternative for aerial imagery collection.

b. 45.23 (b) – Marking Requirements

45.23 (b) requires aircraft to display the roman capital letter “N” with 

registration number and the words “restricted”, “light-sport”, “experimental”, or 

“provisional”, as applicable, on the entrance to the cabin, cockpit, or pilot station 

in lettering that is between 2 in. and 6 in. in height. The eBee Ag is unmanned and 

thus has no cabin, cockpit, pilot station, or entrance on which these required 

markings could be displayed. In addition Pravia may not have a registration 

number assigned by the FAA. As a result Pravia seeks full exemption from this 

regulation. Pravia will to the maximum extent possible comply with the location 

requirements of 45.27 (a) and the size requirements of 45.29 (f). Pravia 
13

specifically proposes to put the word “EXPERIMENTAL” in the largest lettering 

possible on top of the aircraft in accordance with 45.29 (f) “if no surface 

authorized to be marked by 45.27 is large enough for full-size marks, marks as 

large as practicable must be placed on the largest of the authorized surfaces”. 

Pravia also proposes placing a flag at the ground control station with the words 

“EXPERIMENTAL UAS” in 3 in. lettering. 

An equal level of safety would be maintained by displaying the word 

“EXPERIMENTAL” on top of the aircraft and by placing a flag at the ground 

control station with the words “EXPERIMENTAL UAS”. Since the eBee Ag will 

always be within VLOS of the PIC (positioned at the ground control station) and 

flown at a low altitude (400 ft. AGL or less) the markings on airframe and the flag 

located at the ground control station would allow all parties to visually be 

informed of the UAS’ operating status. 

c. 91.7 (a) – Civil Aircraft Airworthiness

91.7 (a) states that “no person may operate a civil aircraft unless it is in an 

airworthy condition”. Pravia is already seeking exemption for airworthiness 

Certification (Reference D.2.a.) and thus no FAA standard will exist for 

determining airworthiness. As a result Pravia seeks full exemption from this 

regulation. 

Pravia will achieve an equal level of safety by using SenseFly’s eBee User 

Manual and Inspection and Maintenance Requirements (Reference Appendix B 

and C) which contain pre-flight protocol for each flight, safety checks, and 

comprehensive maintenance procedures. In addition the eBee Ag has already 
14

demonstrated the ability to fly safely in the NAS under the current NMSU FAAapproved COA, and thus is airworthy.

d. 91.9 (b) – Civil Aircraft Flight Manual in the Aircraft

91.9 (b) states that no person may operate an aircraft unless there is a 

current approved flight manual for the aircraft onboard. The eBee Ag’s small and 

lightweight airframe is not physically capable of carrying an aircraft flight manual 

onboard. In addition to this the eBee Ag is unmanned, and the PIC is located at 

the ground control station. Pravia thus seeks exemption from the requirement to 

carry the aircraft flight manual onboard. Pravia instead proposes that the SenseFly 

eBee User Manual (Reference Appendix B) and Justification of Airworthiness 

Document (Reference Appendix E), which contain information normally found in 

an aircraft flight manual, be kept at the ground control station where it is readily 

assessable to the PIC and Safety Observer for reference. 

If it were physically possible for these required documents to be placed

onboard the aircraft, the PIC and Safety Observer would have no means of 

accessing the information due to the fact that eBee Ag is unmanned with no 

aircrew onboard. Therefore an equal level of safety will be meet by keeping the 

eBee User Manual and Justification of Airworthiness Document at the ground 

control station where it will be readily accessible (within arm’s reach) to the PIC 

who is operating the aircraft, thus meeting the intent of the regulation. 

e. 91.103 – Preflight Action

91.103 requires that the PIC be familiar with specific information before 

each flight such as weather, forecast, and fuel requirements. In addition to this the 
15

PIC must be familiar with information found within the approved flight manual 

relating to aircraft performance and take-off and landing distances. Due to the fact 

that the eBee Ag has no FAA-approved flight manual Pravia seeks exemption 

from this regulation. Pravia proposes to use the SenseFly eBee User Manual 

(Reference Appendix B) and Justification of Airworthiness Document (Reference 

Appendix E) in lieu of an FAA-approved flight manual. These two SenseFly 

publications have extensive pre-flight checklists that include reviewing weather, 

battery requirements, take-off and landing distances, and aircraft performance 

data.

The information found in the SenseFly eBee User Manual and 

Justification for Airworthiness Document is comparable to the information found 

in a FAA-approved flight manual, to include a comprehensive step-by-step preflight checklist. As a result an equal level of safety will be maintained by the PIC 

using these two SenseFly publications, which addresses the items listed in 91.103. 

f. 91.109 – Flight Instruction

91.109 states that “no person may operate a civil aircraft that is being used 

for flight instruction unless that aircraft has fully functioning dual controls”. The 

eBee Ag is operated by the PIC through a ground control station that 

communicates with the aircraft via line of sight (LOS) transmissions. The eBee 

Ag by design does not have fully functioning dual controls and as a result Pravia 

seeks exemption from this regulation. 

Exemption from this regulation requiring dual controls will not create a 

safety hazard, because the eBee Ag is unmanned and does not carry a pilot or 
16

passengers on board. In addition the eBee Ag’s small size and foam airframe is 

significantly less hazardous to persons and structures on the ground than a 

manned, fixed-wing aircraft. Because the eBee Ag ground control station is 

computer based it will be accessible to both the Instructor and Student at all times. 

The “controls” can in essence be passed back and forth between the Instructor and 

Student, achieving an equivalent level of safety as having two sets of controls.

g. 91.119 – Minimum Safe Altitude

91.119 establishes the minimum altitude that civil aircraft may safely 

operate at. 91.119 (c) specifically states that over “other than congested areas” a 

civil aircraft cannot operate below an “altitude of 500 feet above the surface, 

except over open water or sparsely populated areas (and) in those cases, the 

aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or 

structure”. The sole function of the eBee Ag is to fly at low altitudes over 

agricultural plots, which can be categorized as “other than congested areas”. 

Small UAS’, like the eBee Ag, by design are typically flown at altitudes of less 

than 500 ft. AGL and in close proximity to the PIC and Safety Observer to 

maintain VLOS. Pravia has established operating limitations to achieve the 

highest level of safety, specifically that the eBee Ag will not operate above 400 ft.

AGL and that the eBee Ag will remain within VLOS of the PIC and Safety 

Observer. For these reasons Pravia seeks exemption from this regulation. 

An equivalent level of safety will be maintained by only operating the 

eBee Ag over designated sites (Reference 3.C.b). In addition the eBee Ag’s small 

size and foam airframe is significantly less hazardous to persons and structures on 
17

the ground than a manned, fixed-wing aircraft providing the same service. Also 

by operating at an altitude of 400 ft. AGL or less the eBee Ag will be laterally deconflicted from manned aircraft that are subject to this minimum safe altitude 

regulation and thus an equal if not greater level of safety will be maintained. 

h. 91.121 – Altimeter Settings

91.121 requires aircraft to maintain a cruising level or flight level in 

reference to a current reported altimeter setting. The eBee Ag is not equipped with 

a programmable altimeter but rather determines location and altitude via an 

onboard GPS and barometer. Also since the eBee Ag will be operating at or 

below 400 ft. AGL, there is no need to maintain hemispherical cruising altitudes 

for de-confliction with manned aircraft. For these reasons Pravia seeks exemption 

from this regulation. 

An equal level of safety will be achieved through the eBee Ag’s GPS and 

barometer, which provide altitude and location data to the PIC via the ground 

control station. An automatic pre-flight test is done to check the GPS and 

barometer and if any error is found the eBee Ag is prevented from taking-off. 

Also if at any time during flight there is a failure of the GPS or barometer, the 

eBee Ag will initiate an emergency landing. This, combined with the fact that the 

aircraft’s altitude will be visually monitored by the PIC and Safety Observer, 

ensures an equal level of safety is attained in lieu of referencing an altimeter 

setting. Furthermore by operating at or below 400 ft. AGL the eBee Ag will not 

create a hazard to any manned aircraft maintaining hemispheric cruising altitudes 

based on a current altimeter setting.
18

i. 91.151 (a) – Fuel Requirements for Flight in VFR Conditions

91.151 (a) states that no person may begin a flight in Day VFR conditions 

unless there is enough fuel to fly to the intended landing point and fly for 30 

minutes after that point is reached. The eBee Ag is battery operated and does not 

carry fuel. It has a maximum flight time of 45 minutes on a fully charged battery. 

Compliance with the regulation would leave the eBee Ag less than 15 minutes of 

flight time. Pravia seeks full exemption from this regulation due to the fact that 

the risk or danger associated with failing to reach a safe landing point with 30 

minutes of extra “fuel” does not exist with the eBee Ag. The eBee Ag does not 

have to return to a “landing point” but rather can be safely put down anywhere 

over the agricultural plot.

An equal level of safety will be maintained simply by the fact that the 

eBee Ag is designed to safely land anywhere over the agricultural plot in the 

event that the battery is exhausted. Any risk associated with battery duration 

(fuel) in relationship to flight time is mitigated by the fact that eBee Ag has the 

ability to land anywhere and at any given time. 

j. 91.203 (a) & (b) – Civil Aircraft: Certifications Requirements

91.203 requires all civil aircraft to have “within it...an appropriate and 

current airworthiness certificate” that must be “displayed at the cabin or cockpit 

entrance so that is legible to passengers or crew”. Pravia is already seeking 

exemption from the airworthiness certificate regulation and thus requires an 

exemption from this regulation. In addition the eBee Ag due to its size and design 

has no cabin or cockpit, and therefore does not have the ability to affix or carry 
19

certification or registration documents. Furthermore the eBee Ag does not carry 

any passengers or crew for whom the certificate is required to be displayed. 

Pravia proposes that any FAA-required documents be kept at the ground control 

station and that a small placard be affixed to the eBee Ag airframe with 

manufacture, registration, and contact information. 

An equal level of safety will be achieved by having any FAA-required 

documents located at the ground control station where it will be readily accessible 

to the PIC and any other agencies that may require the information. Having a 

placard attached to the eBee Ag airframe will also allow any person or agencies to 

be informed of the UAS’ origin and status.

k. Part 91 Subpart E (91.401-91.417) – Maintenance, Preventative 

Maintenance, and Alterations

These regulations provided the maintenance and inspections requirements 

in reference to Part 39 and Part 43. 91.405 (a) specifically states that “no person 

may perform maintenance, preventive maintenance, and alterations on an aircraft 

other than as prescribed in this subpart and other applicable regulations, including 

part 43 of this chapter”. Pravia seeks full exemption from these regulations due to 

the fact that these sections apply to an aircraft with an airworthiness certificate for 

which Pravia is already seeking exemption.

An equal level of safety will be achieved by using the SenseFly eBee 

Inspection and Maintenance Requirements (Reference Appendix C) which 

provide step-by-step instructions on Regular Maintenance, Preventive 

Maintenance, and Corrective Maintenance. The PIC will be responsible for
20

conducting maintenance in accordance with these procedures. Any eBee Ag 

maintenance that is not covered in these procedures will be performed by the 

manufacturer. Pravia will ensure that all maintenance performed on the eBee Ag 

by the PIC and manufacturer is documented in accordance with 91.407 (a) (1). 

Specifically that the records will include “a description of the work performed; 

and the date of completion of the work performed; and the signature...of the 

person approving the aircraft for return to service”. The PIC will authorize the 

eBee Ag for return to service for all maintenance covered in the eBee Inspection 

and Maintenance Requirements and the manufacturer will authorize the eBee Ag 

for return to service for all maintenance that is outside the scope of the eBee 

Inspection and Maintenance Requirements. Pravia will also ensure that no 

modifications or alterations are made to the airframe that affect the flight 

operating characteristics of the eBee Ag. 

3. How request benefits public as a whole

The eBee Ag is a safe, efficient, and an economical alternative to manned, fixedwing aircraft that are currently being used to conduct aerial imaging of agricultural plots. 

There are a four major reasons why the public would benefit from granting Pravia 

exemptions from these regulations. Authorizing eBee Ag flights over designated sites 

would 1) reduce the number of manned aircraft in the NAS, 2) reduce air and noise 

pollution, 3) reduce the risk to life and property on the ground, and 4) increase 

agricultural economic growth.

Utilizing the eBee Ag in lieu of a traditional manned, fixed wing aircraft will 

result in the overall reduction of manned aircraft in the NAS. Thus there will be less 
21

aircraft that require control and coordination with Air Traffic Controllers (ATC). Because 

the eBee Ag can take-off and land on-site and operate at an altitude of 400 ft. AGL (or 

less) within VLOS of the PIC there is no need for ATC to provide coordination during 

ground, take-off, departure, transit, arrival, and landing phases of flight. As the skies over 

the United States get busier and busier, any small effort to lighten the load of the Air 

Traffic Controllers would be of great benefit to the public. 

At 1.5 lbs. the battery operated eBee Ag with an electric motor provides a much 

quieter alternative to manned, fixed-wing aircraft. Traditionally a manned aircraft would 

have to transit from the departure airport to the desired site and fly at low altitudes to 

achieve high-resolution imagery. The eBee Ag will require no transit time, and the 

electric motor will be exponentially quieter than a twin-engine combustion motor on 

passenger aircraft that is typically used to conduct aerial imaging. In addition the eBee 

Ag requires no fuel since it is battery operated. A manned aircraft on the other hand 

typically burns 20-30 gallons. of aviation fuel per hour which is polluting the air not only 

over the site but over the path of transit and around the airport. Conducting aerial imaging 

with the eBee Ag in lieu of a manned aircraft would thus greatly reduce both air pollution 

and noise pollution which is of great benefit to the public. 

Using the eBee Ag would also greatly reduce if not completely eliminate the risk 

to life and property on the ground. The eBee Ag’s incredibly small size, reduced weight, 

and foam airframe pose no hazard to people or structures on the ground as opposed to a 

manned twin engine passenger aircraft, which has a much greater potential for collateral 

damage. In addition the eBee Ag is unmanned and as a result the risk associated with 

piloting this aircraft is non-existent. Overall the eBee Ag provides a much safer 
22

alternative to manned, fixed-wing aircraft operations for the purpose of collecting aerial 

imagery. 

Lastly using the eBee Ag to provide aerial imagery would result in agricultural 

economic growth. High-resolution data generated from eBee Ag flights would provide 

scientists with invaluable information on biomass estimation, yield monitoring, leaf area 

indexing, and overall crop health. By analyzing this data scientists can make 

modifications to a wide range of variables that will maximize crop yields. More efficient 

crops would allow the U.S. to generate more food for stateside consumption but also 

increase the amount of crops that can be exported to foreign countries. The major 

increase in economic growth in the agricultural industry would energize the U.S.

economy, which in turn would be of great benefit to the public.
