When ejecting over mountainous terrain higher than 8000 ft MSL, which handle should be used to deploy the parachute?

• A. Emergency Release Handle
• B. Manual Override Handle (MOR)
• C. Parachute Release Switch
• D. Altitude Release Trigger

Answer: (B)

In scenarios where ejection occurs over mountainous terrain that exceeds 8000 feet MSL, it is critical to ensure the parachute deploys effectively and safely. The Manual Override Handle (MOR) is the correct choice for this situation because it is specifically designed to allow for the deployment of the parachute manual override in cases of high altitude or irregular deployment conditions.

Using the MOR in such circumstances enables the pilot or crew member to deploy the parachute at a safe altitude to ensure proper opening and descent in challenging terrain. The functionality of the MOR is particularly relevant at higher altitudes, where atmospheric conditions and the potential for obstacles are heightened.

Other methods such as the Emergency Release Handle are intended for releasing the seat or other equipment and are not tailored for parachute deployment in high-elevation scenarios. Similarly, the Parachute Release Switch and Altitude Release Trigger would not apply properly as they may rely on automatic systems that may not be suitable under specific high-altitude conditions where manual control becomes essential for safety. Thus, utilizing the Manual Override Handle ensures the best chance for a successful parachute deployment when ejecting over mountainous terrain at high altitudes.
