Memory item training centers on actions that must be performed immediately from memory during abnormal or emergency situations. These are typically condensed into quick-reference procedures in the QRH, which pilots rehearse so they can recall and execute the steps without looking up details under pressure. This ensures rapid recognition and action when time is critical. Other options don’t fit because large-scale simulations of normal operations focus on standard workflows, detailed maintenance manuals aren’t part of flight crew memory-item drills, and marketing materials have no relevance to flight operations. So, quick-reference procedures on the QRH are the typical component.

In an emergency descent, the first priority is to establish a controlled, rapid descent without letting airspeed run away. Extending the speed brakes fully does that by creating significant drag, which lowers the airspeed and lets you descend at a safe, controllable rate. This quick increase in drag helps you establish a stable flight path before fine‑tuning thrust and pitch. Lowering the landing gear isn’t needed right away and can affect handling or add unnecessary drag if not required. Engaging autopilot isn’t the immediate step in this scenario; you typically adjust the configuration to control the descent first. Throttle idle may be used subsequently to manage airspeed, but the most effective immediate action to set the descent in motion is deploying the speed brakes.

Center tank fuel limitation is tied to the original A320ceo’s center wing tank and its fuel-pump/feed arrangement. That ceo design has a specific restriction on how much fuel can be carried in the center tank under certain conditions to prevent fuel management issues, so the limitation is documented for the A320ceo variant. The A320neo and the other variants use updated center-tank/configuration designs, so that same limitation isn’t required for them. That’s why the center tank fuel limitation applies to the A320ceo.

Memory item training during an abnormal event is about acting instantly with the correct actions to keep the airplane safe and under control. These are the quick, memorized steps pilots must perform without delay so they don’t lose control or mismanage the situation while they start figuring out what’s going on. The goal is to stabilize the aircraft, preserve essential flight parameters like attitude and airspeed, and set up the aircraft for the next steps in the response. This approach is not about gathering data after the event, nor about bloating the crew’s procedures with extra items. It also doesn’t replace human decision making with automation; it relies on trained pilot actions performed from memory to maintain control while the crew analyzes the situation and follows the appropriate, more detailed procedures.
