Agri-Spray Consulting offers professional Application Analysis Clinics for agriculture aircraft. These Operation S.A.F.E clinics allow operators to have their aircraft professionally analyzed for pattern uniformity and droplet size. Test data is interpreted, and if required, changes to the boom set-up are recommended to improve spray performance. Pilots can then do an immediate follow up test to ensure it is set up correctly. Operation S.A.F.E clinics can be tailored for individual operators or for groups and associations.


Pattern Testing Clinics

  • Test new spray equipment or boom reconfiguration.
  • Improve performance, uniformity, and accuracy.
  • Identify any deposition or uniformity issues that exist within the spray pattern.
  • Determine the optimum swath width for each individual aircraft.
  • Determine and adjust droplet size.
  • Allow for adjustments or changes to the equipment in order to improve pattern uniformity and swath width.
  • Reduce spray drift potential.
  • Demonstrate professionalism to your customers. 


One-on-one aerial application consultations provide operators and pilots with research based information on proper boom set-up for attaining an efficient and effective spray pattern and swath width, while reducing spray drift potential.

This guide contains diagrams of precise nozzle and boom placement (See example), boom and nozzle placement photos, optimum swath width, and coefficient of variation across the application.   

The boom set-up diagrams are from aircraft that were tested for pattern uniformity and efficiency with very good results.  If you would like to receive a  digital copy of a specific diagram, please fill out a request and we will be happy to send it to you via email.   Due to the numerous application variations, the diagram should be referenced for initial set-up or reconfiguration, followed by a pattern test to ensure the pattern is uniform and to determine the optimum swath width.
