When is the QRG used?

The Quick Reference Guide (QRG) is primarily utilized in non-normal situations after all established memory items have been addressed. This tool is designed to provide immediate guidance on managing unusual or emergency scenarios that may arise during flight operations. By consulting the QRG, flight crew members can access structured procedures and checklists tailored to address specific situations, ensuring that they follow appropriate protocols to mitigate risks and maintain safety.

In contrast, while routine checks before flights, normal operational situations, or managing delays and cancellations are essential aspects of flight operations, they typically rely on other resources or standard operating procedures rather than the QRG. The QRG is intended for times when quick, specific instructions are necessary to respond effectively to critical in-flight situations, which underscores its importance in emergency preparedness and safety management.
