- Pattern Analysis Workshops: He has conducted hundreds of workshops worldwide. The resulting research and practical findings have directly impacted aircraft design, nozzle, and spreader performance, leading manufacturers to incorporate better and safer designs into aerial applicator products.
Development of Analytical Systems and Tools
- WRK Pattern Analysis Systems: Dr. Gardisser co-developed the landmark WRK pattern analysis technologies, including string, granular, drift tower, and DropletScan systems, all of which are now used globally by operators, manufacturers, and regulators to assess and optimize spray and dry material delivery.
- Guidelines for Specialized Applications: His expertise has helped shape protocols for diverse operations—mosquito abatement, Asian Soybean Rust control, oceanic oil spill response, fire-fighting, and much more.
Industry Education, Leadership, and Advocacy
- Operation S.A.F.E.: For more than a decade, Dr. Gardisser has led Operation S.A.F.E. schools, training over half of the nation’s active S.A.F.E. analysts, ensuring continual technical excellence and safety for the industry.
- PAASS Program: Served on the development team and as an active presenter for the Professional Aerial Applicator Support System (PAASS), advancing pilot and operator education on safety, drift minimization, and best practices.
- Consultancy and Industry Service: Consulted with Air Tractor to develop their drop boom system—improving spray uniformity and reducing drift. Delivered product enhancement seminars for 16 consecutive years at the NAAA national meeting.
Regulatory and Public Engagement
- Outreach: Presented to EPA, FAA, USDA, state agencies, the chemical industry, and legislative bodies to advocate for practical, science-based aerial application practices and to promote the safety and value of ag aviation.
- Broad Industry Influence: Member of agricultural aviation associations in multiple U.S. states and in Canada; served on numerous influential committees, including as past chair of NAAA/ASABE technical sessions, and as co-chair of the U.S. Coalition for Drift Minimization.
Pilot Credentials and Community Resource
- Flight Instruction and Ag Pilot: Dr. Gardisser is a commercial pilot, CFI, and actively flies ag aircraft—including the Air Tractor. He is well-known for his accessibility—annually responding to hundreds of calls from applicators seeking technical advice, often free of charge.
- Commitment to Training: He calibrates and analyzes, on average, 250 aircraft per year and offers recertification and safety credit instruction in an average of eight states annually.
