When raising an aerial device, until what point should the fly sections be extended?

The correct answer is that the fly sections should be extended until the tip is slightly above the target. This practice ensures that the aerial device is optimally positioned for effective operation. By extending the tip just above the target, the driver/operator allows for necessary maneuverability and adjustment without overextending the aerial device. This positioning is particularly important when aiming to make precise placements for rescue operations or when delivering water to the desired location.

Additionally, it helps maintain stability, as extending too far beyond the target can introduce unnecessary risk of instability or difficulty in controlling the device. While ensuring the base is stable and not exceeding a 45-degree angle are relevant considerations during the operation, they do not directly address the specific point at which extension should be completed for effective operations in context with the target. Ensuring the apparatus is fully extended may seem intuitive but can lead to reduced control and potential safety hazards.
