Spray Performance Calculations and Tradeoffs

Spray Performance Calculations and Tradeoffs

Aviation is, like all engineering pursuits, full of tradeoffs. You can fly farther but carry less payload and travel slower, or you can fly faster but burn much more fuel and lose some range. You can go supersonic with small, thin, wings, but then you can’t slow down for landing below 170kts. You can land at 45kts, but then you will cruise at only 110kts. It’s much the same with the payload/spray rate/coverage relationship for spray aircraft. If you are spraying at ULV rates of .5gpa, you can cover 10 times more area than you can when spraying at 5gpa,…
