AERIAL APPLICATION TEST PAPER 2025/2026
QUESTIONS AND ANSWERS GRADED A+
✔✔The droplet size at which spray drift becomes a concern is: - ✔✔200 and below
✔✔Aircraft suitable for aerial application of pesticides must be: - ✔✔Must be able to lift,
transport and disperse pesticides safely
✔✔One of the reasons for an adequate vent in the aircraft pesticide tank is to -
✔✔Prevent a vacuum from altering the normal flow of liquid.
✔✔The purpose of baffles inside a liquid spray tank is to: - ✔✔Reduce sloshing of the
liquid during flight.
✔✔Hydraulic agitation of the mixture in the aircraft spray tank requires: - ✔✔Sufficient
pump output capacity.
✔✔A proper functioning positive cutoff valve with a suck-back feature will supply
pressure to the boom and nozzles when the spray flow is stopped - ✔✔High positive.
✔✔The purpose of bleed valves at the ends of the spray boom is to: - ✔✔Prevent
pressure from building up from trapped air when the spray valve is opened.
✔✔To accommodate for the influence of prop wash on spray pattern, it is necessary to:
- ✔✔Reposition the nozzles on the spray boom
✔✔The advantage of an electronic sprayer volume controller is that it: - ✔✔Reduces or
increases the spray output as airspeed changes
✔✔Ram-air spreaders can - ✔✔Compromise fixed wing aircraft performance
✔✔The purpose of adjusting ram-air spreader vanes is to - ✔✔Improve the granule
distribution pattern.
✔✔The purpose of calibration is to - ✔✔Apply the correct amount of pesticide.
✔✔Applying a pesticide at a rate that is higher than the pesticide label rate is: -
✔✔Illegal
✔✔Increasing airspeed without changing the spray output will result in: - ✔✔Less
pesticide active ingredient applied per acre
, ✔✔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
