Introduction

Quick Action Index (QAI)

: Located on the front page, this index provides immediate access to time-critical checklists for serious situations like engine fires or cabin depressurization.

• Follow memory items first: Execute bolded immediate actions from memory, then consult the QRH to complete the checklist.
• Verify and cross-check: Pilot flying performs actions; pilot monitoring reads and verifies every step aloud. Use challenge-and-response discipline.
• Prioritize flying and navigation: Always maintain aircraft control and safe flight path before detailed checklist work. If necessary, fly the aircraft and then complete the QRH.
• Use appropriate checklist version: Operators may have company-specific QRH supplements; use the company-approved version and the latest revision.
• Communicate with ATC early: Declare emergency or nature of problem as needed, request priority handling and routing, and coordinate diversion/airport selection.
• Consider performance and landing configuration: Some checklists change weight/landing distance—recalculate or consult performance tables in the QRH or FCOM/AFM.
• Time-critical decisions: If the QRH directs immediate diversion or landing, plan approach and use stable approach criteria consistent with the abnormal situation.

• Engine failure/engine fire: Memory items (thrust levers—idle, engine start/stop, fire handle—pull), secure failed engine, and identify fire indications.
• Smoke, fire, or fumes: Immediate actions include oxygen masks, crew communication, donning masks, and checklist flows for smoke source isolation.
• Cabin pressurization loss: Rapid descent and altitude/airspeed management memory items, passenger oxygen deployment checks.
• Electrical system faults: Cross-check generator/APU status, essential bus shedding, and checklist for loss of AC/DC power options.
• Hydraulics and flight controls: Identification of failed hydraulic systems, related flight control limitations, and considerations for asymmetric flight or alternate flight control laws.
• Fuel system anomalies: Fuel imbalance, suspected fuel leak, and APU crossfeed/transfer procedures.
• Landing gear/extension problems: Alternate extension procedures, speed and configuration limits, and landing considerations.
• Evacuation: Time-critical memory items (park brake, APU off, evac command) and brief evacuation flow emphasizing passenger safety and slide use.

At the end of many checklists, you will see instructions like: "Accomplish the following checklist(s) if required..." boeing 737-800 qrh quick reference handbook

The QRH serves as the primary reference for managing non-normal tasks when flight deck systems (like ECAM/EICAS) cannot detect a failure or as a backup to those systems. Its philosophy focuses on , providing a clear process for identifying, assessing, and executing responses to critical flight events. 2.
