1. A Category 34 applicator is applying a granular insecticide to a 500-acre pine
plantation. The aircraft’s swath width is set to 75 feet, and the application rate is 50
pounds per acre. What is the primary factor that will determine the actual effective
swath width for this application?
a) The aircraft's calibrated airspeed
b) The prevailing wind speed and direction at canopy level
c) The specific gravity of the granular material
d) The pilot’s visual reference to the tree tops
Answer: b) The prevailing wind speed and direction at canopy level
Rationale: In aerial applications, the effective swath width is heavily influenced by
environmental conditions, especially wind. While the mechanical swath width is set on the
ground, wind will cause material to drift laterally, altering the distribution pattern and the
actual area covered effectively. Airspeed (a) affects application rate, not swath width.
Specific gravity (c) affects how the material falls but not the lateral displacement caused
by wind. Visual reference (d) is for navigation but doesn't define the biological swath.
2. When conducting an aerial application near a sensitive crop, such as a certified
organic blueberry farm, which of the following buffer zone management strategies is
most critical for a Category 34 applicator to implement?
a) Using the highest possible spray pressure to atomize droplets for rapid evaporation
b) Applying only during temperature inversion conditions to keep the spray
concentrated
c) Orienting flight lines parallel to the sensitive area and reducing boom pressure on the
,downwind side
d) Increasing airspeed to create a finer droplet spectrum that dissipates quickly
Answer: c) Orienting flight lines parallel to the sensitive area and reducing boom
pressure on the downwind side
Rationale: To protect sensitive areas, flight lines should be parallel to the border to prevent
direct overflight. Reducing pressure on the downwind side (using a turn-off or rate
controller) minimizes drift potential. High pressure (a) creates finer droplets, which
increase drift risk. Inversions (b) trap small droplets in a concentrated layer, allowing them
to move off-target for long distances. High airspeed (d) also generally increases drift by
creating smaller droplets and higher momentum for lateral movement.
3. During a pre-flight inspection for a helicopter used in Category 34 operations, the
applicator notices a significant amount of play in the tail rotor pitch control linkage.
What is the most appropriate immediate action?
a) Note the discrepancy in the logbook and monitor it during the first flight of the day
b) Apply a temporary lubricant to reduce friction and minimize the perceived play
c) Adjust the rigging to manufacturer’s specifications using the onboard tool kit
d) Ground the aircraft immediately and have a certified mechanic inspect the system
Answer: d) Ground the aircraft immediately and have a certified mechanic inspect
the system
*Rationale: The tail rotor control system is a critical flight control. Any abnormal play
indicates a potential mechanical failure (e.g., worn bearings, loose bolts) that could lead
to loss of directional control. The Category 34 applicator is the pilot-in-command and is
responsible for the airworthiness of the aircraft. Only a certified mechanic with
appropriate authorization can inspect and repair flight control systems (a, b, c).*
4. A Category 34 applicator is using a GPS guidance system with a lightbar for swath
guidance. The system is set to “parallel swaths” based on an A-B line. The field has a
slight slope that was not accounted for in the initial A-B line setup. How will this affect
application accuracy?
a) Swaths will remain perfectly parallel but will drift downhill over time due to
,gravitational pull on the aircraft
b) Swaths will shift progressively downslope, causing skips and overlaps if the pilot does
not manually correct
c) The GPS will automatically correct the swath lines in real-time based on the aircraft’s
barometric altimeter
d) The system will become unusable as it cannot maintain accuracy on any terrain that is
not perfectly flat
Answer: b) Swaths will shift progressively downslope, causing skips and overlaps if
the pilot does not manually correct
Rationale: A standard GPS lightbar system using an A-B line creates parallel lines based
on the initial heading. If the field is sloped, flying perpendicular to the slope without a
terrain-compensating system will cause the aircraft’s ground track to shift, leading to
uneven swath placement. More advanced RTK or terrain-compensation systems are
needed to prevent this. The system does not automatically adjust for slope (c) unless it is a
specialized topographic guidance system.
5. Which of the following statements best describes the legal responsibility of the
Category 34 certified applicator regarding the pesticide label during an aerial
application?
a) The label is a guide, but the applicator can modify rates based on aerial application
best practices to ensure efficacy
b) The label is the law; the applicator must follow all directions, restrictions, and
prohibitions specific to aerial application
c) The label requirements only apply to the person purchasing the pesticide, not the
hired aerial applicator
d) The applicator is only responsible for the application portion; mixing and loading are
the responsibility of the ground crew
Answer: b) The label is the law; the applicator must follow all directions,
restrictions, and prohibitions specific to aerial application
Rationale: Under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) and Georgia
state law, it is a violation to use a pesticide in a manner inconsistent with its labeling. The
, Category 34 applicator, as the person applying the pesticide, is directly responsible for
ensuring compliance with all label directions, including specific aerial application sections,
buffer zones, and prohibited use statements.
6. When calibrating an aerial spray system, the term “Nozzle Flow Rate” is essential. If an
applicator increases airspeed by 20% while keeping pressure and nozzle configuration
constant, what must be done to maintain the same gallons per acre (GPA) application
rate?
a) Decrease the swath width by 20%
b) Increase the flow rate from the nozzles by 20%
c) Decrease the flow rate from the nozzles by 20%
d) No change is needed as GPA is independent of airspeed
Answer: b) Increase the flow rate from the nozzles by 20%
Rationale: GPA is calculated as (Flow Rate) / (Swath Width x Speed). If speed increases, to
maintain the same GPA, the total flow rate must increase proportionally. This is typically
achieved by increasing system pressure or using larger nozzles. If speed increases and flow
rate stays constant, the GPA decreases.
7. A weather forecast for a spray operation predicts a strong temperature inversion
developing in the late afternoon. What is the primary risk associated with spraying
during a strong inversion?
a) Rapid evaporation of small droplets before they reach the target
b) Enhanced vertical mixing that carries droplets above the target canopy
c) Formation of a stable layer that allows small droplets to remain suspended and move
laterally for long distances
d) Increased volatility of the pesticide carrier, leading to vapor drift
Answer: c) Formation of a stable layer that allows small droplets to remain
suspended and move laterally for long distances
Rationale: During a temperature inversion, cool air is trapped near the surface under a
layer of warmer air, suppressing vertical air movement. Small spray droplets can become
trapped in this stable layer and, with even a light breeze, can be carried great distances
