What type of aircraft is most commonly used for aerial application?

The most commonly used type of aircraft for aerial application is indeed fixed-wing aircraft and helicopters. These aircraft are specifically designed and adapted for the unique requirements of crop spraying and other aerial applications. Fixed-wing aircraft are favored for their ability to cover large areas quickly and efficiently, making them ideal for extensive agricultural fields. Their speed and range allow operators to apply pesticides, fertilizers, and other chemicals over vast landscapes within a short time, maximizing productivity.

Helicopters, on the other hand, are particularly beneficial in situations where precision is crucial, such as applying substances in uneven terrain or near sensitive areas like water bodies or residential properties. Their superior maneuverability and ability to hover make them suitable for targeted applications and situations that require specific spray patterns.

In contrast, options such as hot air balloons and gliders are not suitable for aerial application due to their lack of control and speed needed for effective pesticide delivery. Military drones, while capable of certain aerial tasks, are not the primary choice for agricultural spraying due to limitations in capacity and regulations surrounding their use. Commercial jets are designed for passenger transport and do not feature the equipment or design needed for the specialized tasks of aerial application.
