Which of the following is NOT a factor to consider during aerial rescues?

In aerial rescue operations, the focus is typically on factors that directly impact the safety and success of the rescue mission. Wind speed and direction are critical to understand how they can affect the aerial vehicle's stability and the trajectory of the rescue operation. The victim's physical condition is essential to assess since it informs the rescue team of the proper technique and timing required for the rescue, ensuring they can provide appropriate care during the operation. Distance to safety matters because it affects the planning and execution of the rescue, as the further the distance, the more complex the operation can become.

The firefighter's weight, while important for overall operations and equipment load limits, is generally not a primary consideration during the planning of an aerial rescue itself. Instead, the focus is placed on the aforementioned factors that directly influence the operation's safety and efficiency. Thus, it is reasonable to conclude that the firefighter's weight is not a critical factor in the context of aerial rescues compared to the other considerations listed.
