What type of items does the QRG checklist include?

The QRG (Quick Reference Guide) checklist is designed to provide essential information that can be quickly accessed during operations. It typically includes memory items and reference items that pilots and flight crew need to recall and reference in high-pressure situations. These items are crucial for ensuring safety and consistency in procedures. Memory items refer to actions or procedures that must be committed to memory due to their importance in emergency or routine situations, while reference items provide general guidance or standards for operations that may not require memorization but are still critical to have on hand. This makes option C the most aligned with the purpose of the QRG checklist.

In contrast, the other choices focus on aspects that may not fall under the typical usage of a QRG. Safety procedures and emergency contacts, while critical for overall safety, are often covered in documentation beyond just the quick reference format. Cost-saving tips and operational guidelines, as well as inspection checklists and repair guidelines, also do not align with the primary focus of the QRG checklist, which is to provide immediate, easily accessible information for operational situations.
