What action must you complete before dropping in over any obstructions on swath approach?
- ansTurnaround
Do not make turns over the following at any time? - ansResidences, poultry houses, livestock,
and ponds/reservoirs.
Minimum altitude you must maintain during ferrying flights? - ans500ft AGL
When ferrying never fly directly over what kind of buildings? - ansFarm buildings
During ferrying flights it is good practice to do what on each new run? - ansDeviate course
1/8-1/4 of a miles from your previous course
Aerial application equipment is calibrated according to what metric? - ansAPM or Acres per
minute
DGPS-mediated flow controllers do what? - ansAdjust flow dependent on aircraft speed
Application height is the distance between what two things? - ansnozzle tip/spreader exit
plant canopy
Small droplet sprays require what sort of application heights? - ansApplication 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? - ansDyed water
When spray pattern testing with oil based test liquid, what sort of cards should be used? -
ansOil sensitive cards
Effective swath is: - ansThe span of the spray pattern that contains enough pesticide to obtain
the desired result/pest control
Overall swath is: - ansThe 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? - ansLow 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? - ansScout 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? -
ansBreaks in cultivation or plant cover, trees, buildings, telephone poles, guy wires etc.
Guy wires generally pull in which direction in relation to circuitry wire? - ansThe OPPOSITE
side
What must you determine about nearby buildings assumed to have electricity? - ansThe route
by which they get their electricity
If there is an obstruction beside a field, how should it be handled? - ansFly close and parallel
to the obstruction
If there is an obstruction at the end of a field, how should it be handled? - ansOne or two
swath widths prior to reaching the obstruction, cut off spray and pull up. After those passes
are complete, fly one or two parallel clean up passes to catch the swaths you cut off early for.
What are the different types of ground crew members? - ans-On site field crew
-Mix/load crew
-Application equipment servicing crew
What jobs do the On Site Field Crew perform? - ans-Current weather conditions
