Which of the following is not a recommended action after confirming the "Eject" sequence?

After confirming the "Eject" sequence, it is essential to prepare for immediate ejection, which involves focusing on actions that maximize survival and safety during the process. Ensuring the seatbelt is fastened is not a recommended action in this context because once the decision to eject has been made, the seatbelt should actually be loosened or unfastened to facilitate a rapid escape from the aircraft. The ejection seat is designed to propel the pilot away from the aircraft, and being secured could hinder a safe exit.

In contrast, checking altitude, preparing for impact, and assessing surrounding airspace are all critical actions to take before and during the ejection process. These steps help ensure that the pilot is aware of their environment and can improve their chances of survival upon ejection and descent.
