Abstract
This invention relates to a method and system for increasing safety in chemical application from an aircraft. Wind speed, wind direction and other critical flight parameters are measured, calculated, recorded, and visually or audibly announced during the aircraft flight via onboard equipment, which parameters provide a means for the aircraft pilot to control chemical spray application and for unassisted automatic chemical spray cutoff and for limiting spray application outside an application zone or target area. Such parameters also provide a means for indicating the lift reserve of the aircraft and a means for determining atmospheric stability near the ground and providing the pilot with a record of the meteorological conditions at a particular location. The method and system of the present invention also provide a means for predicting appropriate aircraft upwind offset distance to compensate for predicted chemical spray drift.
