The back of the QRH contains vital performance tables. If an emergency forces a 737-800 to land with partial flaps or an inoperative engine, its landing distance will change. The QRH provides instant calculations for: Inflight landing distances based on runway braking action. Flap-extension penalties. V-speed adjustments for non-normal configurations.
While commercial airlines customize their QRHs to meet regulatory requirements, the core technical procedures are produced by Boeing for the 737-600/-700/-800/-900 series. Key Characteristics

The "Break Glass In Case of Emergency" book. 💥✈️ We practice the "Normal" every day, but the QRH is where the real test lies. From the basics of an APU fire to the complexity of a Dual Engine Failure, this binder holds the answers when the alarms start ringing.
Tapping a system fault can automatically calculate landing performance based on current weather. The back of the QRH contains vital performance tables
This is the bulk of the book. Organized by system (Pneumatics, Electrical, Flight Controls), you only turn to this section after completing memory items. Examples include:
(Terrain warnings, TCAS alerts, windshear recovery). 3. Performance Inflight Data (PI) Flap-extension penalties
Training emphasizes scenario-based rehearsals that couple systems knowledge with QRH flows to build automaticity under stress.
