    • 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.
    • 本发明涉及一种提高飞机化学应用安全性的方法和系统。 风速,风向和其他关键飞行参数通过机载设备在飞机飞行过程中进行测量,计算,记录和视觉或听觉通知,这些参数为飞行员驾驶员控制化学喷雾应用和无辅助自动化学喷雾 并且用于限制在施用区域或目标区域之外的喷涂应用。 这些参数还提供了一种用于指示飞机的升力储备的手段,以及用于确定地面附近大气稳定性的手段,并向飞行员提供特定位置的气象条件的记录。 本发明的方法和系统还提供了一种用于预测适当的飞机逆风偏移距离以补偿预测的化学喷雾漂移的装置。
