Often organized by "Memory Items" (actions done immediately without looking at the book) followed by "Action Items" (actions taken after reading the checklist). B. Emergency Procedures
This is the core of the handbook. It features color-coded pages (usually amber or red borders) to differentiate between urgent emergencies and urgent-but-stable abnormal conditions. 3. Performance Inflight Section (PI)

Most 737-800 fleets now use a hybrid system: a paper backup QRH in the cockpit plus a primary electronic version on the EFB (Electronic Flight Bag).
Unlike a normal checklist (Do-Confirm), the QRH in an emergency is "Read & Do." The PM reads a step: "Engine Start Lever (affected engine)... CUTOFF." The Pilot Flying confirms: "CUTOFF." The PM reads: "Fire Switch (affected engine)... Pull." Once pulled, the PM reads: "Fire Switch... Rotate to STOP and HOLD FOR 1 SECOND." It features color-coded pages (usually amber or red
Similar to the inflight section, the PD chapter provides performance data for takeoff under abnormal conditions. For instance, if a takeoff must be conducted with a system inoperative (like the air conditioning packs), the PD section will provide adjusted speeds (V1, VR, V2) and required runway lengths.
The 737-800 QRH is engineered for maximum scannability under extreme stress. It is divided into distinct, color-coded sections based on aircraft systems and urgency levels. 1. The Cover and Quick Action Index
This section outlines how to use the manual, including how to handle multiple malfunctions simultaneously. 2. Non-Normal Checklists (NNC)
