What does the manual override handle (MOR) allow the pilot to do?

The manual override handle (MOR) is a critical component designed specifically for emergency situations. It allows the pilot to manually initiate seat/pilot separation, which is essential in scenarios where automatic systems may fail or when immediate action is necessary to ensure safety. This feature is particularly crucial in high-stress conditions, such as ejection or other emergency scenarios, where the timely separation from the aircraft can be lifesaving.

The other options do not accurately reflect the function of the manual override handle. Adjusting the seating position freely relates to seat controls but not to the MOR’s purpose. Activating the canopy fracturing system is a separate emergency function that does not involve the MOR. Similarly, controlling the emergency oxygen supply is another part of the aircraft's systems that operates independently of the manual override handle. Thus, the correct answer highlights the critical safety role of the MOR in emergency seat ejection processes.
