Why is it recommended to eject from an aircraft in a level flight attitude?

Ejecting from an aircraft in a level flight attitude is recommended primarily to ensure little or no sink rate upon ejection. When an aircraft is in level flight, it maintains a stable altitude and minimizes vertical movement. This position can enhance the effectiveness of the ejection seat and the safety of the pilot during ejection.

In level flight, the relative motion of the pilot and the aircraft is controlled, which prevents a sudden drop or significant vertical velocity that could complicate the ejection process. Moreover, ejecting in this manner can help ensure that the pilot is in the best position to safely deploy the parachute and gain control once separated from the aircraft.

Other options, while they may have merits in other contexts, do not specifically support the recommended practice of ejection in a level flight attitude. Thus, maintaining a near-zero or minimal sink rate is critical for ensuring safety and successful recovery during an emergency ejection, making this the most appropriate practice in such situations.
