Under what conditions is the manual override (MOR) handle used?

The manual override (MOR) handle is specifically designed to be utilized in situations where the automated systems are not functioning as intended, particularly during critical phases of flight. In the context of ejection systems, it is essential for safety and effective handling of emergencies.

The correct answer revolves around the circumstances under which the MOR handle is engaged. It is important for pilots to manually intervene if the ejection sequence fails, ensuring that they can take necessary actions to ensure speed and safety under adverse situations. The reference to separation above 14,000 to 16,000 feet MSL pertains to the operational altitudes where manual control becomes crucial due to increased safety requirements and the need for optimal performance in emergencies.

Thus, the correct application of the MOR handle aligns with the critical conditions that a pilot may encounter while operating the aircraft, highlighting the importance of manual control in high-stakes situations.
