What is the purpose of the emergency checklist?

The purpose of the emergency checklist is to provide procedures in case of system failures or emergencies. This is crucial for ensuring safety during flight. An emergency checklist outlines specific steps a pilot must take to address various malfunctions or adverse situations, allowing them to respond quickly and effectively. These procedures are carefully designed to reduce risks and enhance the chances of a successful outcome during an emergency.

In contrast, while enhancing performance in normal operations, recording flight data, and assisting in fuel calculations are important aspects of flying and managing the aircraft, they do not pertain to the primary function of an emergency checklist, which is strictly focused on safety and emergency response.
