When are crews required to perform a manual obstacle analysis?

Crews are required to perform a manual obstacle analysis in multiple scenarios to ensure the safety and effectiveness of their flight operations. Conducting this analysis when in Visual Meteorological Conditions (VMC) with planned see-and-avoid operations is essential, as it helps the crew identify any potential obstacles that could interfere with their ability to maintain visual separation from other aircraft or terrain.

Additionally, performing an obstacle analysis when an obstacle is present on the departure path is critical since understanding the surrounding environment is vital for planning a safe takeoff and climb-out. This analysis also applies when there is a possibility that obstacles may impede an emergency briefing plan. By recognizing these obstacles, the crew can ensure that they have a solid emergency plan that accounts for any potential hazards along their intended flight path.

Given these considerations, the requirement to perform a manual obstacle analysis in all these circumstances underscores the comprehensive approach to safety and operational integrity, making it essential for crews to be vigilant and proactive about obstacle awareness. Thus, indicating that the answer encompasses all scenarios presents a holistic view of safety protocols in aviation operations.
