PREVIEW
The B737MRG is the most trusted reference for professional airline pilots flying the Boeing 737. Today, more than 85,000 pilots worldwide rely on the MRG as part of their daily operations.
Built on the QRH, the B737MRG goes further by providing practical, experience-based guidance on how to manage malfunctions and how to efficiently continue the flight.
In short, the MRG starts where the QRH ends — bridging the gap between checklist compliance and real-world decision-making.
Below are six key factors that define the B737MRG.

Frequently asked Questions
There are several excellent Boeing 737 handbooks that describe aircraft systems in detail. The MRG is different!
The MRG starts where the FCOM and QRH end, providing practical, operational guidance on how to manage abnormals — both on the ground and in flight.
Consider a simple example: STARTER VALVE OPEN
Most B737 system guides will explain what the engine bleed system does and why the fault may occur. What they typically do not explain is how to manage the malfunction in real-world conditions.
The MRG addresses the questions pilots actually need answered:
- Can you continue the flight safely, or is an immediate diversion required?
- What are the operational consequences of continuing with this failure?
- How does the failure affect engine performance, fuel consumption, system redundancy, RNAV / RVSM / ETOPS operation?
- Are there differences in handling between NG and MAX aircraft?
- What are the implications for engine thrust, pressurization, and anti-ice?
- Can the issue be mitigated by system reconfiguration or circuit breaker action
- Is this an MEL NOGO after landing?
- How do you handle compound failures, such as Engine Anti-Ice Valve OPEN?
These are the types of questions the MRG is designed to answer!
All guidance is based on line pilot experience and authoritative Boeing technical documentation, including the FCOM, QRH, AMM, SDS and other — translated into clear, practical decision-making support for everyday line operations.
The MRG is not distributed as PDF.
You can download the app for iOS and Android.
The B737MRG was first published twenty years ago and has been continuously updated ever since. Thousands of hours of research, writing, validation, and revision have been invested in the MRG handbooks.
An active mobile app subscription includes all content updates, which are released regularly. The app itself also is continuously enhanced, with new features and functionality added to better support the needs of pilots and maintenance engineers.
The B737MRG paper handbook can be purchased through your local dealer. For bulk orders of more than five handbooks, please contact me directly.
