The Aircraft-Integrated Meteorological Measurement System (AIMMS), a tool that can be installed on ag aircraft and used by aerial applicators to monitor in-flight weather conditions in real time, is developed. It enhances aerial applicators’ ability to mitigate drift by measuring wind speed and direction, temperature and humidity in flight. Real-time weather data is transmitted to the Global Positioning System (GPS), which lines the aircraft up accordingly to account for the air movement. By checking the temperatures at different heights, AIMMS can also detect the presence of an inversion. Since off-target drift is very likely to occur in a temperature inversion, ag pilots refrain from making aerial applications in those conditions.
