What aspect is NOT included in the ROC criteria for obstacle clearance?

The aspect that is not included in the ROC (Remotely Operated Clearance) criteria for obstacle clearance is related to pilot decision making. The ROC criteria focus on measurable and technical elements that ensure safety and efficiency in operations, such as aircraft performance standards, system functionality, and NAVAID (navigational aid) performance. These criteria are essential for determining whether the aircraft can safely navigate considering the obstacles in its flight path.

In contrast, pilot decision making, while crucial in actual flight operations and during the execution of any flight maneuver, is generally not quantified within the ROC criteria. Instead, the focus is on the capabilities and performance of the aircraft and supporting systems, which can be objectively assessed. This distinction is important for understanding how regulatory bodies establish safe operational parameters without delving into the subjective nature of human decision-making in flight scenarios.
