Which of the following is a key component of the premeditated ejection posture?

The key component of the premeditated ejection posture is having the elbows tucked in. This position is important because it helps to protect the aviator's arms from potential injury during the ejection sequence. When the elbows are tucked in, it reduces the risk of them being struck by the canopy during ejection and helps to ensure a more streamlined and safe exit from the aircraft. This posture stabilizes the body as the forces of ejection occur, allowing the aviator to maintain better control during the ejection process.

While having the feet flat on the floor, eyes focused forward, and head up can also be beneficial for awareness and readiness, the primary focus of the premeditated ejection posture is on minimizing injury by keeping the body compact, which is achieved effectively by tucking in the elbows. This ensures that the aviator is in the best possible position to survive the ejection.
