When calibrating a granule applicator, it's crucial to accurately measure application airspeed, output rate, and swath width.

Application airspeed refers to the speed at which the aircraft is flying when the granules are being applied. This variable is critical because it directly affects how the granules spread across the target area. Too fast of an airspeed may cause uneven distribution or even drift, while too slow can lead to overlapped areas.

Output rate pertains to the volume of granules released per unit area. This is essential for ensuring that the correct amount of material is applied, which is vital for effective pest control or fertilization without waste or crop damage. Monitoring the output rate helps ensure compliance with agricultural regulations and best practices.

Swath width measures the lateral coverage of the granules as they are dispensed from the applicator. Knowing the swath width helps operators effectively plan the flight pattern and spacing of successive passes to ensure full coverage of the treated area without overlaps or gaps.

Together, these three variables ensure that the application is done efficiently, effectively, and in accordance with the required specifications for pest management or crop production.
