This document is engineered to forge academic theory into elite operational competence within
the agricultural aviation and pesticide application sector. By mastering these 30 hyper-focused
scenarios, you will internalize the precise intersection of federal aviation law, state agricultural
regulations, and modern Unmanned Aircraft System (UAS) operational frameworks, ensuring
flawless execution in high-stakes environments.
The "Critical Axioms" Cheat Sheet
● The Weight Threshold (UAS): Drones under 55 lbs operate under 14 CFR Part 107 with
a Part 137 Agricultural Aircraft Operator Certificate (AAOC) and a § 107.36 exemption.
Drones 55 lbs and over require 14 CFR Part 91, a Part 137 AAOC, an FAA Section 44807
Exemption, and the Pilot in Command must hold a Third-Class Medical Certificate.
● The 2026 EPA Dicamba Mandate: The federal maximum application rate is 0.5 lbs of
acid equivalent per acre per application. Absolutely zero applications are permitted if the
forecasted temperature is 95°F or higher on the day of, or the day after, the planned
application.
● The State Preemption Rule: Arkansas legally imposes stricter parameters than the EPA.
The absolute state cutoff for over-the-top (OTT) dicamba is June 30. Furthermore,
Arkansas mandates a 1/2-mile buffer for specialty/organic crops and a 1-mile buffer for
university or USDA research stations.
● The Arkansas Classification System: Class E and Class F (which includes 2,4-D and
MCPA) chemicals demand a Custom Applicator Permit (Form DP-32), a designated
Operator-in-Charge, and a $250 financial deposit with the State Plant Board. Class H is
, strictly reserved for Dicamba.
● The Congested Area Doctrine (14 CFR § 137.51): Dispensing operations over
congested areas strictly require prior written approval from the local governing body,
localized public notice, and a comprehensive flight plan approved by the responsible FAA
Flight Standards office.
PART II: THE ELITE TEST BANK
Tier 1: Foundational Syntax & Application
Q1: An operator intends to utilize a multi-rotor Unmanned Aircraft System (UAS) with a
maximum takeoff weight of 65 lbs for the aerial application of a liquid fertilizer. Based on the
principles of the FAA Regulatory Framework, which action/conclusion is the MOST
ACCURATE? A) The operator may operate solely under 14 CFR Part 107 provided they obtain
an Agricultural Aircraft Operator Certificate (AAOC) prior to dispensing. B) The operator must
register the aircraft via the FAADroneZone portal and secure a Part 107.36 exemption for the
carriage of hazardous materials. C) The operator must obtain an FAA Section 44807
Exemption, a Part 137 AAOC, and the Pilot in Command must possess a Third-Class Medical
Certificate. D) The operator is exempt from obtaining a medical certificate if the operation is
conducted strictly over rural, non-congested agricultural areas under 400 feet AGL.
● The Answer: C (The operator must obtain an FAA Section 44807 Exemption, a Part 137
AAOC, and the Pilot in Command must possess a Third-Class Medical Certificate.)
● Distractor Analysis:
○ A is incorrect: 14 CFR Part 107 is strictly limited to UAS weighing less than 55 lbs.
An aircraft weighing 65 lbs unequivocally exceeds this regulatory threshold and is
pushed into Part 91.
○ B is incorrect: Drones weighing 55 lbs and over must be registered through the
Traditional Aircraft Registration process (Civil Aviation Registry Electronic Services
or CARES), not FAADroneZone, which is strictly reserved for sub-55 lb aircraft.
○ D is incorrect: Operations conducted under a Section 44807 Exemption for heavy
UAS require the Pilot in Command to hold a Third-Class Medical Certificate
universally, regardless of the population density of the operating area.
The Mentor's Analysis: The 55 lb gross weight threshold is the absolute operational divide in
FAA UAS regulations. Crossing this barrier transitions the aircraft out of the simplified Part 107
framework into the heavier, highly regulated Part 91 environment, necessitating a Section 44807
Exemption to bridge the gap for agricultural operations. Professional/Academic Intuition:
Mass dictates jurisdiction. A takeoff weight of ≥55 lbs universally triggers Part 91,
Section 44807, and mandatory pilot medical certification.
Q2: Under the 2026 Environmental Protection Agency (EPA) regulations regarding over-the-top
(OTT) dicamba applications on tolerant soybeans, what is the FIRST weather-related restriction
an applicator must mathematically verify before commencing spraying operations? A) Ensure
the ambient air temperature does not exceed 85°F at the exact time of the application. B) Verify
the ambient temperature is not forecasted to reach or exceed 95°F on the day of the application
or the day following the application. C) Confirm that rain is not forecasted within the next 24
hours to prevent extreme aquatic runoff and watershed contamination. D) Check that the wind
speed is below 15 mph to comply with standard baseline state spray drift regulations.
● The Answer: B (Verify the ambient temperature is not forecasted to reach or exceed
, 95°F on the day of the application or the day following the application.)
● Distractor Analysis:
○ A is incorrect: While some individual states (such as Illinois) independently use an
85°F cutoff, the 2026 federal EPA standard explicitly prohibits application if the
forecast meets or exceeds 95°F. Between 85°F and 95°F, operators are permitted
to spray, but are restricted to treating only 50% of their acreage.
○ C is incorrect: The specific EPA restriction regarding rainfall prohibits application
within 48 hours of forecasted rainfall, not 24 hours.
○ D is incorrect: While wind speed must always be monitored, the absolute
disqualifier introduced in the new 2026 federal framework is the two-day 95°F
temperature forecast rule, which is designed to eliminate dangerous chemical
volatility during high-risk conditions.
The Mentor's Analysis: The EPA’s 2026 regulatory shift replaced fixed calendar cutoffs with
dynamic, temperature-based forecasting to combat the unique vapor-drift physics of dicamba.
The critical restriction window spans 48 hours (the day of and the day after application) to
ensure the chemical does not vaporize after settling. Professional/Academic Intuition:
Volatility is a direct function of sustained heat; the 95°F 48-hour forecast is a federal hard
deck that cannot be bypassed.
Q3: The Arkansas State Plant Board classifies agricultural pesticides to rigorously regulate their
distribution, storage, and application. Based on the principles of the Arkansas Rules on
Pesticide Use, which action/conclusion is the MOST ACCURATE regarding a Class F
pesticide? A) It consists solely of glyphosate-containing products and requires the applicator to
maintain a 1-mile buffer from all organic specialty crops. B) It includes all 2,4-D containing
pesticides and MCPA, and its legal application requires an agricultural firm to hold a Custom
Applicator Permit. C) It is strictly reserved for dicamba products and explicitly prohibits any tank
mixing with glyphosate to prevent increased volatility. D) It designates highly experimental
pesticides that require a Section 18 Emergency Exemption for legal use within state borders.
● The Answer: B (It includes all 2,4-D containing pesticides and MCPA, and its legal
application requires an agricultural firm to hold a Custom Applicator Permit.)
● Distractor Analysis:
○ A is incorrect: Glyphosate is legally designated as a Class G pesticide under
Arkansas rules.
○ C is incorrect: Dicamba is exclusively designated as a Class H pesticide, which
carries its own distinct set of severe regulatory restrictions.
○ D is incorrect: Class F is not utilized for experimental use; it is a permanent
classification specifically targeting 2,4-D and MCPA products.
The Mentor's Analysis: Arkansas geographically segregates high-liability herbicides into
specific alphanumeric classes to enforce rigorous oversight. Class E and Class F (which
uniquely isolates 2,4-D) are the only classifications that legally define an operation as a Custom
Application, triggering the need for a DP-32 permit and a designated Operator-in-Charge.
Professional/Academic Intuition: Class F = 2,4-D = Custom Applicator Permit. Never
conflate the alphanumeric classifications of high-liability herbicides.
Q4: A commercial operator is preparing to apply a Class H pesticide (dicamba) via aerial
application in eastern Arkansas on May 15. Based on the principles of Arkansas specific
dicamba rules, which action/conclusion is the MOST ACCURATE? A) The operator must
maintain a 240-foot downwind spray buffer from all non-dicamba tolerant row crops. B) The
operator must tank mix the dicamba with glyphosate to ensure maximum herbicidal efficacy and
physical drift reduction. C) The operator must maintain a 1-mile physical buffer in all directions
