Name one risk factor when conducting aerial applications.

When conducting aerial applications, one significant risk factor is the potential for collision with obstacles such as power lines and trees. Aerial applicators operate at low altitudes to effectively distribute pesticides, fertilizers, or seeds, which significantly increases the risk of encountering fixed objects. While flying at low levels, the pilot's ability to see and avoid these obstacles can be compromised, especially when operating in areas with dense foliage or infrastructure.

In addition, the risk of collision is heightened by the fact that pilots must frequently maneuver around varying terrains and comply with specific application guidelines that may limit their flight paths. Proper risk assessment and thorough pre-flight planning are crucial in mitigating this hazard, including studying the application area for known obstacles and implementing flight patterns that avoid them.

While the other factors mentioned, such as heavy rain, limited visibility from clouds, and excessive pilot fatigue, are also important considerations in aerial applications, the risk of collision with physical obstacles directly impacts the safety and success of the operation and requires immediate attention during flight operations.
