How do ram-air spreaders affect fixed wing aircraft performance?

Ram-air spreaders, when used on fixed-wing aircraft, can lead to compromised performance. These devices create additional drag as they introduce turbulence and modify airflow around the aircraft. The added complexity of managing airflow can result in a decrease in overall aerodynamic efficiency. As the drag increases, the aircraft may require more power to maintain speed, which can limit its operational capabilities.

In specific scenarios, while ram-air spreaders can enhance the distribution of fertilizers or pesticides, they also impact the flight dynamics, particularly at lower speeds or during critical phases of flight such as takeoff and landing. This effect on performance highlights the trade-offs involved in using such equipment, emphasizing the need for careful consideration of aircraft stability and efficiency.
