When should the manual override (MOR) handle be utilized?

The manual override (MOR) handle is specifically designed to be used in situations where the automatic deployment system is compromised. This is particularly crucial when there is a system failure, meaning the automatic parachute deployment cannot initiate as expected. In addition, if there is a need to deploy the parachute at altitudes greater than 15,000 feet Mean Sea Level (MSL), the MOR handle becomes essential, as it provides the pilot with the ability to manually control parachute deployment, ensuring safety under high-altitude conditions.

Utilizing the MOR handle at these critical moments ensures that the aircrew can still safely exit the aircraft if necessary, especially when automatic systems are unresponsive. This underscores the importance of being prepared for such emergency situations where human intervention is required for effective outcomes.

Pre-flight checks, landing, and cabin pressure loss are scenarios where other procedures would typically be sufficient or required before considering the use of the MOR, making them less appropriate contexts for utilizing this specific function.
