Once the memory items are completed and the flight path is stabilized, the pilot monitoring (PM) opens the QRH to verify that every memory step was done correctly and to finish the remaining reference steps. Reference Checklists

It uses "Checklist" formats rather than long paragraphs of theory.

The primary objective of the QRH is to guide pilots safely from the onset of a malfunction to a safe landing. It bridges the gap between complex engineering systems and time-critical decision-making.

Specifically for the 737-800 model, the QRH contains:

Divided by aircraft systems (e.g., Fire Protection, Hydraulics, Electrical) for rapid navigation. Structure of the QRH

Crucial warnings and cautions are highlighted in bold boxes.

Not all emergencies allow time to open a book. The 737-800 QRH divides safety tasks into two distinct phases: (Recall Items) and Reference Checklists . Memory Items (Recall Tasks)

The is the most critical safety document carried inside the cockpit of the world’s most popular narrow-body commercial airliner. Developed by The Boeing Company and tailored by individual airlines, this document serves as the definitive guide for flight crews to manage non-normal, abnormal, and emergency situations safely.

– Addresses GPWS (Terrain) alerts, TCAS (Traffic) resolution advisories, and windshear escape maneuvers. Performance Data Sections

The Pilot Flying never looks at the QRH; their sole job is maintaining control of the aircraft path.

Instantly applying maximum braking, closing thrust levers, and deploying speedbrakes.

Some emergencies happen too fast to read a book. The QRH identifies "Memory Items"—critical steps that must be performed from memory before the handbook is even opened. Examples include: Cabin Altitude Warning / Rapid Depressurization Aborted Engine Start

The Boeing 737-800 QRH is divided into several sections, each addressing a specific aspect of aircraft operation:

Only after these immediate actions are completed does the PM reach for the to complete the remaining steps.

AUTOTHRUST (If engaged) ...... DISENGAGE Crew Action: THRUST LEVER (affected engine) ...... CONFIRM CLOSED
