The Boeing 737-800 Quick Reference Handbook (QRH) is the most critical document in the cockpit for managing inflight non-normal situations. It provides flight crews with structured, checklist-based procedures to handle everything from minor system faults to catastrophic emergencies. Purpose of the QRH boeing 737800 qrh quick reference handbook
Every checklist begins with a clear statement of why the checklist is being read and what it aims to achieve.
Training often involves multiple, compound failures, forcing pilots to prioritize which QRH checklists to use first. This section explains the "rules of the road
The QRH is engineered for rapid navigation under high-stress conditions. It uses a highly structured, tabbed format divided into system-specific chapters that match the overhead panel layout and the Flight Crew Operations Manual (FCOM).
Tables for calculating landing distances and speeds under non-normal conditions (e.g., with specific systems inoperative). Purpose of the QRH Every checklist begins with
Always apply (anti-ice, bleed config).
Text blocks formatted in italics or boxed outlines offer crucial operational warnings, such as reductions in remaining flight time, changes to automated systems (like autopilot restrictions), or revised landing configurations.
Only after these immediate actions are completed does the PM reach for the to complete the remaining steps.
These are used for conditions that allow time for systematic troubleshooting. Pilots open the QRH, find the checklist via the index, and read each step aloud. : Isolating the affected pump.
