AERIAL APPLICATION STUDY GUIDE 2025/2026
QUESTIONS AND ANSWERS RATED A+
✔✔If 1700 ounces of material is collected from nozzles on a helicopter spray boom in
90 seconds, what is the total flow volume in gallons per minute? - ✔✔8.85 gal/min
✔✔An aircraft spraying system has an output volume of 8 gallons per minute. How
many gallons are sprayed per mile when the aircraft travels at 130 miles per hour? -
✔✔3.7 gal/ mile
✔✔An effective swath width is the: - ✔✔Width of a single pass that includes portions of
overlaps from other passes
✔✔An aircraft sprays 20.2 gallons per minute. How many minutes of spraying time are
needed to spray out 147 gallons of spray mixture? - ✔✔7.3
✔✔Given an application rate of 11.3 gallons per acre, how many acres can be sprayed
with 147 gallons of spray mixture - ✔✔13
✔✔If an aircraft treats 14 acres per tank of spray mixture, how many pints of pesticide
liquid should be put into the spray tank to apply at a volume of 1.5 pints per acre? -
✔✔21
✔✔How many acres are in a rectangular field that measures 620 feet by 1280 feet? -
✔✔18.2
✔✔The last application flight of the day: - ✔✔Requires the same attention as every
other flight.
✔✔Varying the application speed without changing flow volume during an application
will: - ✔✔Result in uneven coverage
✔✔The application pattern that helps to avoid flying through spray from a previous
swath is the: - ✔✔Racetrack pattern
✔✔Ferrying flights must be made at an altitude of at least: - ✔✔500 Feet
✔✔Ferrying flights that pass over areas where people live or work should - ✔✔Be
varied by 1/8 to 1/4 mile for each trip
✔✔Breaks seen in the normal cultivation patterns of a field may alert the pilot to: -
✔✔Hidden Hazards
, ✔✔Too wide or too narrow overlapping of spray passes will result in - ✔✔Uneven
Applications Patterns
✔✔To avoid the adverse effect of headwinds or tailwinds on an application volume, you
should fly: - ✔✔Crosswind or 45 degrees to the crosswind
✔✔Which of the following would have little effect on the safety and effectiveness of an
application if changes occur during the operation - ✔✔Moving the operation to a
different mixing loading location.
✔✔The problem with flying too low when making a granule application is that: -
✔✔Granules are still moving horizontally at lower heights
✔✔Which of the following has a strong influence on where the nozzles are placed along
the boom near the belly of the aircraft? - ✔✔Propeller Slip
✔✔To clear a leaking needle and seat style check valve the pilot should first: - ✔✔Pull
up on the needle to flush the valve of debris
✔✔which component should the pilot check first if they notice that a decreased pressure
from what was initially required is now needed in order to maintain the desired gallons
per acre - ✔✔nozzle tips for orfice wear
✔✔which of the following should a pilot do when he observes dripping nozzles while
parked on the loading pad with the aircraft turned off? - ✔✔check the condition of the
check valve
✔✔to ensure you have not overcompensated for spray pattern due to prop wash, a pilot
should - ✔✔conduct pattern testing
✔✔What is the term used for high peaks on the edges of spray patterns - ✔✔Wing tip or
Rotor Vortex
✔✔Relative to the trailing edge of the wing, how are spray boom for most fixed wing
aerial applications best positioned? - ✔✔Slightly Below and Behind
✔✔What is a clogged in-line screen most likely to cause - ✔✔A lower application rate
✔✔Which of the following indicated the spray valve is operating properly when it is in
the closed position? - ✔✔The Boom Pressure gauge shows a low negative PSI
