DETAILED VERIFIED ANSWERS
/ALREADY GRADED A+
In what direction with the wind should you fly when pattern testing? - ANS-Fly the plane
directly into the wind if there is any.
What is the max wind speed that you should perform pattern testing in? - ANS-Less than
10mph
What is the name of the group that performs spray pattern testing for aerial applicators using
spray pattern analyzing computers? - ANS-NAAA: National Aerial Applicators Association
How many yards prior to the testing line should you operate your boom for before and after? -
ANS-100 yards
What two things should you look for when pattern testing if using visual evaluation? - ANS--
Light spray pattern near the flight centerline
-Uneven spray densities towards the wingtips
The effective swath width when measured on string or cards is where on a graph? - ANS-The
distance between the midpoints of the sloping ends of the pattern.
,Spray pattern testing can help identify which different kinds of problems? - ANS--Leaks
-Nozzle problems
-Incorrect droplet spectrum
-Propwash displacement
-Wingtip vortex
-Rotor wash
Wingtip vortex is usually characterized by what pattern on swath width graphs? - ANS-High
peaks at its edges
Ram air spreader swath width testing should utilize how man foam lined 4 inch deep shallow
pans? - ANS-At least 13
If there is wind when dry spreader testing, how should you position your collection pans, and
how should you fly in relation to the wind? - ANS-Pans should be placed at a right angle to the
prevailing wind, and you should fly directly into the wind.
What is one way to get an even application using a spreader that creates a triangular shaped
pattern? - ANS-Fly using half the width of the pattern as the swath spacing. (remember the
overlapping triangle pattern test graph)
For a trapezoidal swath pattern, how do you measure effective swath width? - ANS-The distance
between the two pans with no product caught, and the distance between the two pans with
equal amounts of product collected, divided by two. EX: 60ft+30ft /2= Effective swath width
of 45 ft
How do you determine the GPM on a spray boom? - ANS-Multiply the per nozzle GPM rate at a
selected pressure, by the number of nozzles. EX: If there are 50 #D4-46 nozzles operating at
0.48 gmp, your boom output rate will be 24 gpm.
,List the steps you can use to confirm that the amount of spray being delivered is what you
expect: - ANS--Fill the tank with a known quantity of water
-Perform your spray operation for a specific amount of time
-Refill the aircraft to the beginning amount
-Check the amount it took to refill against expected spray volume usage for the operation
What action must you complete before dropping in over any obstructions on swath approach? -
ANS-Turnaround
Do not make turns over the following at any time? - ANS-Residences, poultry houses, livestock,
and ponds/reservoirs.
Minimum altitude you must maintain during ferrying flights? - ANS-500ft AGL
When ferrying never fly directly over what kind of buildings? - ANS-Farm buildings
During ferrying flights it is good practice to do what on each new run? - ANS-Deviate course
1/8-1/4 of a miles from your previous course
Aerial application equipment is calibrated according to what metric? - ANS-APM or Acres per
minute
DGPS-mediated flow controllers do what? - ANS-Adjust flow dependent on aircraft speed
Application height is the distance between what two things? - ANS-nozzle tip/spreader exit
plant canopy
, Small droplet sprays require what sort of application heights? - ANS-Application heights of 8-
10ft above canopy for droplet sizes in the 150-200 micron range
What sort of water could you use for spray pattern testing? - ANS-Dyed water
When spray pattern testing with oil based test liquid, what sort of cards should be used? - ANS-
Oil sensitive cards
Effective swath is: - ANS-The span of the spray pattern that contains enough pesticide to
obtain the desired result/pest control
Overall swath is: - ANS-The outermost range that spray droplets within your pattern will reach
but are not enough to result in satisfactory pest control
In what type of outdoor conditions is it best to perform spray pattern testing? - ANS-Low wind
conditions generally in the morning, if winds are measurable, fly the aircraft INTO the wind to
conduct spray pattern testing.
What is the first thing you should do prior to conducting a spray operation? - ANS-Scout the
target site from the air to identify obstacles, terrain, and field layout
What should you specifically look for when scouting a field aerially prior to an application? -
ANS-Breaks in cultivation or plant cover, trees, buildings, telephone poles, guy wires etc.
Guy wires generally pull in which direction in relation to circuitry wire? - ANS-The OPPOSITE
side
