Mastering this specific test bank translates directly to elite operational and legal competence by
forcing the synthesis of highly specific 2026 Environmental Protection Agency (EPA) pesticide
mandates, Federal Aviation Administration (FAA) aviation law, and Arkansas State Plant Board
regulations into real-world, split-second decision-making. By discarding rote memorization in
favor of structural logic, practitioners will achieve an expert-level command of agricultural
aviation, ensuring uncompromising environmental, physical, and legal safety.
The "Critical Axioms" Cheat Sheet
, ● The Aerial Dicamba Absolute (2026/2027 EPA Mandate): All over-the-top (OTT)
dicamba products (e.g., Stryax, Engenia, Tavium) strictly prohibit aerial application. This
includes both manned aircraft and Unmanned Aircraft Systems (UAS). If an OTT dicamba
application is aerial, it is unequivocally illegal.
● The 95°F / 50% Rule: Under 2026 EPA labels, OTT dicamba application is subject to a
hard stop if the forecasted temperature reaches 95°F. Between 85°F and 94°F, applicators
may only treat 50% of untreated dicamba-tolerant acres per county per day.
● The Heavy UAS Hard Deck (>55 lbs): Any agricultural drone weighing 55 lbs or more at
takeoff requires an FAA Section 44807 Exemption, an FAA Part 47 N-number registration,
a Class 3 Medical Certificate, and an active Part 137 Agricultural Aircraft Operator
Certificate.
● The Volatility & Drift Mandate: Every OTT dicamba application requires a doubled
Volatility Reduction Agent (VRA) at 40 oz/acre, an approved Drift Reduction Agent (DRA),
and a strict 240-foot downwind spray drift buffer. Ammonium sulfate (AMS) tank mixes are
strictly prohibited.
● The Calibration Constant: Total aircraft flow rate is determined by the formula: GPM =
(GPA × MPH × Swath in inches) ÷ 5940.
● Arkansas Classification Hard Deck: Class F designates 2,4-D/MCPA and requires a
Custom Applicator Permit. Class G designates Glyphosate in >1 gal containers. Class H
designates Dicamba, which is subject to an Arkansas June 30 cutoff and 1-mile university
buffers. Class J designates Warfarin for feral hog control.
PART II: THE ELITE TEST BANK
Tier 1: Foundational Syntax & Application
Q1: An Arkansas-based Part 137 commercial operator is contracted to apply the 2026
formulation of Stryax (dicamba) over-the-top (OTT) on dicamba-tolerant (DT) soybeans using a
manned fixed-wing agricultural aircraft. Based on the 2026 EPA federal registration and
Arkansas State Plant Board rules, which action is the MOST ACCURATE? A) The operator may
proceed provided they maintain a 240-foot downwind buffer and add 40 ounces of a Volatility
Reduction Agent (VRA). B) The operator must restrict application to 50% of the field if the
temperature is between 85°F and 94°F. C) The operator must unequivocally decline the
contract, as all aerial applications of OTT dicamba products are strictly prohibited. D) The
operator may proceed only if operating a UAS (drone) under a Section 44807 exemption, as
only manned aerial application is banned.
● The Answer: C (The operator must unequivocally decline the contract, as all aerial
applications of OTT dicamba products are strictly prohibited.)
● Distractor Analysis:
○ A is incorrect: While VRAs and buffers are mandatory for OTT dicamba, they do not
authorize aerial application, which is universally banned for these products.
○ B is incorrect: The 50% temperature limitation is a valid 2026 rule for ground
applications, but the method of application (aerial) invalidates the entire operation.
○ D is incorrect: The EPA prohibition on aerial OTT dicamba application applies to all
aircraft, including UAS, regardless of FAA 44807 exemptions.
The Mentor's Analysis: The method of application supersedes all other chemical mitigating
factors in the regulatory hierarchy. When facing an OTT dicamba scenario under the 2026 EPA
, registrations, the immediate priority is verifying the application vector. The EPA analysis
recognized that historical drift issues required the strongest protections in agency history,
leading to an absolute ban on aerial dispersion to prevent long-range off-target movement. By
utilizing the Aerial Prohibition Rule, the practitioner bypasses the common trap of calculating
buffers and temperatures for an inherently illegal flight. Professional/Academic Intuition: No
OTT dicamba label allows aerial application. If the aircraft leaves the ground with OTT dicamba,
it constitutes a severe federal environmental violation.
Q2: A commercial applicator purchases a new agricultural spray drone which has a maximum
takeoff weight exceeding 55 pounds. Before dispensing economic poisons, which combination
of FAA regulatory approvals must the operator FIRST secure? A) A Part 107 Remote Pilot
Certificate and a simple DroneZone registration. B) A Section 44807 Exemption, a Part 47
N-number registration, a Class 3 Medical Certificate, and a Part 137 Certificate. C) A Part 133
External-Load Certificate and a Special Airworthiness Certificate. D) A Part 137 Certificate, a
state Custom Applicator permit, and an FAA DroneZone registration.
● The Answer: B (A Section 44807 Exemption, a Part 47 N-number registration, a Class 3
Medical Certificate, and a Part 137 Certificate.)
● Distractor Analysis:
○ A is incorrect: Part 107 alone only covers drones under 55 lbs and does not permit
heavy drone operations or agricultural dispensing.
○ C is incorrect: Part 133 applies to external-load operations such as firefighting
helicopter buckets, not standard agricultural spray drones.
○ D is incorrect: Drones over 55 lbs cannot use the simplified DroneZone registration;
they require traditional paper-based Part 47 registration to receive an N-number.
The Mentor's Analysis: Aviation weight classes directly dictate the severity of federal oversight
and the complexity of the certification pipeline. When operating a drone over 55 lbs, the
immediate priority is securing heavy-aircraft authorizations because the kinetic energy of the
system transcends standard Part 107 safety assumptions. The FAA relies on Section 44807
exemptions combined with Class 3 Medicals to ensure pilots are physiologically and legally
equipped to manage this elevated risk. By utilizing the 44807 Heavy Drone Framework, the
practitioner bypasses the novice error of treating an industrial spray drone like a recreational
quadcopter. Professional/Academic Intuition: 55 pounds is the absolute legal threshold where
Part 107 privileges end and Section 44807 exemptions begin.
Q3: The Arkansas State Plant Board classifies pesticides to provide additional state-level
restrictions beyond the federal label. Under these rules, which classification is MOST
ACCURATE for a product containing the active ingredient dicamba? A) Class F B) Class G C)
Class H D) Class J
● The Answer: C (Class H)
● Distractor Analysis:
○ A is incorrect: Class F is exclusively reserved for 2,4-D and MCPA products.
○ B is incorrect: Class G designates glyphosate-containing products packaged in
containers of one gallon or larger for agricultural use.
○ D is incorrect: Class J is exclusively for warfarin when used as a feral hog toxicant.
The Mentor's Analysis: State regulatory boards categorize chemicals to streamline regional
enforcement and address localized agronomic vulnerabilities. When applying restricted
chemicals in Arkansas, the immediate priority is identifying the state-specific Class to ensure
compliance with overlapping jurisdictional mandates. The Class H designation specifically
triggers severe operational constraints, such as the June 30 cutoff and one-mile omnidirectional
buffers around university research stations. By utilizing the Class H Designation, the practitioner
