2025|2026 Q&A | Instant Download Pdf
1. What is the primary advantage of aerial pesticide application
compared to ground application?
a) Reduced pesticide drift
b) Increased accuracy of spot treatments
c) Ability to cover large areas quickly
d) Less equipment maintenance
Rationale: Aerial application allows rapid coverage of large areas,
especially in agriculture and forestry.
2. Which federal agency regulates the use of pesticides in the United
States?
a) USDA
b) EPA
, c) OSHA
d) FAA
Rationale: The Environmental Protection Agency (EPA) is responsible
for registering and regulating pesticides under FIFRA.
3. In Pennsylvania, who issues the licenses for aerial pesticide
applicators?
a) EPA
b) FAA
c) Pennsylvania Department of Agriculture (PDA)
d) USDA
Rationale: The PDA regulates and licenses commercial and aerial
applicators in Pennsylvania.
4. What is the primary environmental concern with aerial applications?
a) Equipment breakdown
b) Drift and off-target deposition
c) Reduced yield
d) Increased soil compaction
Rationale: Drift is a major concern in aerial spraying due to wind and
height of release.
5. What is the minimum safe altitude for an aircraft when not engaged in
application over congested areas?
a) 200 feet
b) 500 feet
, c) 1000 feet
d) 50 feet
Rationale: FAA regulations require aircraft to maintain at least 500
feet above ground level in most areas.
6. Which meteorological factor most increases the risk of pesticide drift
during aerial spraying?
a) High humidity
b) Strong winds
c) Low cloud cover
d) High barometric pressure
Rationale: Wind can carry spray droplets off-target, making it the
greatest drift risk factor.
7. What droplet size category is preferred for minimizing drift in aerial
application?
a) Very fine
b) Medium to coarse
c) Ultra-fine
d) Fog-like mist
Rationale: Larger droplets are less prone to drift compared to fine or
mist droplets.
8. What FAA document must aerial applicators comply with to ensure
safe flying practices?
a) FAR Part 141
, b) FAR Part 137
c) FAR Part 91
d) FAR Part 61
Rationale: FAR Part 137 covers agricultural aircraft operations,
including pesticide application.
9. Which pesticide formulation is most likely to produce drift problems
during aerial spraying?
a) Granules
b) Emulsifiable concentrates
c) Dusts
d) Wettable powders
Rationale: Emulsifiable concentrates atomize into very small
droplets, increasing drift risk.
10. Which nozzle type produces the largest droplets, helping reduce
drift?
a) Hollow cone
b) Flat fan
c) Flooding nozzle
d) Air induction
Rationale: Flooding nozzles produce large droplets that resist drift.
11. Which weather condition can cause pesticide droplets to remain
suspended and move off target later?
a) High humidity
