The B737MRG is the most trusted professional reference for airline pilots flying the Boeing 737.

The B737MRG covers 300 different non-normals, that is a hundred more than the official QRH. The app provides system notes and practical advice on how to deal with each non-normal, both on ground and in flight. The app comes with over 2,200 illustrations, logic gates, lights and schematics!

Captain Pat BOONE, author of the B737 MRG, is a senior instructor with more than 20,000 flight hours on Boeing aircraft (Boeing 737, Boeing 767 and Boeing 787 Dreamliner).

You can free download the app and review a couple of demo pages. You need a paid subscription to access the entire content. With a subscription you get access to all editions of the B737MRG (CL, NG, MAX) in all languages (English, Chinese). Your subscription includes all updates of the content that are published by the author on a regular basis.

The new update has major bugs... that were fixed.

Great resource, but the latest update BROKE THE APP. No menu items are functional. When selected, all menu items except Search display a blank white screen. The only way I can display content is to use the search function. Please fix ASAP.

Uninstalled/reinstalled version 7.2.6 twice. Same result on my IPad Air, iOS 12.4.6

//update// bug fixed in less than a week. Nice work.

Since the new update of table of contents I cannot use the application. I go into the app and it says free demo. I restore my subscription which is valid till next year march. I download the NG data files. Loading is complete I can then use the application no problems. If I close the app and reopen it (not minimise) it then goes back to free demo mode. I have to download everything again. I have removed the app and downloaded it from the App Store. I have restarted my device. No idea what to do now.

Editing my review as the developer has introduced a table of contents. Thanks. Much easier to navigate now.

Previous comment
The previous version there was an overview of all the chapters and you could easily select the chapter and go to the sub categories. With the new version it seems you have scroll to the chapter you want. Please introduce some sort of table of contents to help make this process quicker. Otherwise the rest of the new app is good.

Great Apps to all 737 Pilots

The literature given to 737 pilots to address Non Normal scenarios was exceptionally well-crafted and presented huge amount of valuable knowledge. The investment made in acquiring it was undoubtedly justified, and the developer deserves praise for his outstanding effort. I have recommended this apps to many of my trainees for their own benefits.
