The primary function of the QRH is to provide immediate guidance when a technical problem or emergency arises. It serves several critical roles:
Small notes explaining system behavior during the checklist execution.

These cover non-time-critical failures, such as a single hydraulic system loss or a minor electrical bus fault. The pilot monitoring reads these checklists aloud straight from the QRH, verifying each step with the pilot flying before manipulating any switch. The Anatomy of a QRH Checklist
The Boeing 737-800 Quick Reference Handbook (QRH) is the most critical document in the cockpit for managing non-normal and emergency situations. Developed by Boeing and customized by individual airlines, this document provides flight crews with standardized, step-by-step checklists to diagnose and mitigate system failures. The primary function of the QRH is to
Unlike memory items, most QRH procedures are designed to be read by one pilot and executed by the other (or by the pilot flying, depending on company procedures). Structure and Contents of the 737-800 QRH

The 737-800 QRH is more than a book of lists. It is a thoroughly engineered system for managing the unexpected. From the memory items drilled into pilots during initial type rating to the last deferred item reviewed before landing, the QRH ensures that no matter what challenge arises in the flight deck, there is always a guide to follow. In the unforgiving environment of high-altitude flight, this organized and reliable reference provides the clarity and confidence that allows crews to remain cool, collected, and in command.
