Boeing 737-800 Quick Reference Handbook (QRH) is a pilot's essential tool for managing in-flight technical problems and emergencies. Structured for rapid navigation under high pressure, it provides a concise, prioritized set of procedures that reduce response time and minimize errors. Key Features of the B737-800 QRH Quick Action Index (QAI):
Located on the front cover, this index lists critical "time-critical" emergencies—such as cabin pressure loss, engine fire, or smoke—allowing pilots to immediately access the necessary checklists. Non-Normal Checklists (NNC):
The bulk of the manual consists of step-by-step instructions for malfunctions. These are organized by aircraft system (e.g., electrical, air systems, fuel) or unannunciated issues like fuel leaks. Memory Items:
For certain life-threatening situations, pilots must perform specific "memory items" by heart before referencing the QRH to confirm and complete the procedure. Performance Inflight (PI) Data:
Includes tables and charts for calculating critical data such as landing distances on contaminated runways or fuel consumption with one engine inoperative. Maneuvers Section:
Provides standardized procedures for complex maneuvers like windshear escape, upset recovery, and rejected takeoffs. Evacuation Checklist: boeing 737800 qrh quick reference handbook
Positioned at the very back for immediate access, this checklist is always read and performed (never from memory) to ensure a safe aircraft egress. Operational Use In the flight deck, the QRH is typically kept in the First Officer's side pocket . When a malfunction occurs, the Pilot Monitoring (PM)
identifies the problem, retrieves the handbook, and reads the checklists aloud, while the Pilot Flying (PF)
focuses on controlling the aircraft and confirms every critical action before it is executed. for the Boeing 737-800?
The Boeing 737-800 Quick Reference Handbook (QRH) is the primary manual for flight crews to handle abnormal and emergency situations. Unlike the much larger Flight Crew Operations Manual, the QRH is a compact, stand-alone tool designed for rapid use during high-stress flight phases. Structure and Purpose
The 737nd QRH is organized into distinct sections to help pilots find critical information immediately. Its core layout includes: Boeing 737-800 Quick Reference Handbook (QRH) is a
Quick Action Index (QAI): Located on the front cover or first pages, this index lists time-critical emergencies like engine fires, rapid depressurization, and rejected takeoffs.
Non-Normal Checklists: The bulk of the book is divided by aircraft system (e.g., fuel, hydraulics, electrics), using large fonts and visual aids like flowcharts and decision trees to reduce pilot cognitive load.
Performance Inflight Data: Contains tables and charts for calculating landing distances or fuel requirements under degraded aircraft conditions.
Normal Checklists: Typically found on the back cover for easy access during routine operations. Operational Use
In an emergency, the QRH is used after performing "Memory Items"—critical steps pilots must execute immediately without consulting a book. Once the aircraft is stabilized, the Pilot Monitoring reads the QRH aloud while the Pilot Flying monitors for accuracy. This coordination is essential for verifying that the correct checklist is selected and that all consequences of inoperative items are understood. Evolution and Modernization Drill memory items weekly (engine fire, cabin altitude,
Boeing continuously updates the QRH based on incident data and research into human factors. For example, modern versions like the B737 QRH New Format focus on making checklists easier to navigate and using visual distinctions to prevent crew error. These updates ensure that even as aviation technology advances, the QRH remains a robust, reliable "cheat sheet" for pilots.
