B737 Alerts is a handy reference guide to the error messages produced by Boeing 737-600, -700, -800, -900, and BBJ series. Designed for professional pilots and maintenance personnel, B737 Alerts covers three types of errors: - Those from the PFD/ND (Next Generation only) - Those from the FMC - Those from the panel modules. In all, nearly four hundred errors are covered. Control head annunciations are cross-linked to QRH procedures as a handy study aid. As always, your FAA-Approved Flight Manual is the final authority as to the safe operation of your airplane, but this is a great training aid for those new in type, studying the systems, or facing a checkride. Each error has a link to a detailed description of the error as well as suggestions for immediate corrective action. Messages are also classified by system and ATA chapter, thus helping you focus on your FCOM or maintenance manual for additional research. B737 Alerts was developed by Bill Bulfer, a recently retired captain with a major airline with extensive time in type. Bill is also the author of the Cockpit Companion series and the FMC Guide, soon to be adapted for the iPad. ## Key features - Covers 737-600, -700, -800, -900, and BBJ series errors - Details PFD/ND, FMC, and panel module errors - Includes nearly 400 errors - Cross-links annunciations to QRH procedures - Provides error descriptions and corrective actions - Classifies messages by system and ATA chapter ## Recent user reviews (10 of 16) All indexed reviews: https://appshunter.io/ios/app/b737-alerts/id453260249/reviews.md ### 3/5 — Problem are here but not pilot actions… *2021-10-20* This apps is definitely very useful …but what the pilot should do if he sees this kind of annunciation is not there…pilot guide line missing… ### 1/5 — Update *2017-10-11* Needs to be updated for operating with iOS 11. Not working at the moment. ### 5/5 — Useful but limited. *2013-06-24* This is a good app for the messages that show up on the screens. It also has good information on the System lights for a quick reference. It does not go into systems level information like the iPad app does. I recommend buying the iPad app even though it's more expensive. That said this is a great app to have in your back pocket! Bill Bulfer has an excellent reputation from his books on 737 systems. I trust his work and his apps seem to have the same passion for the subject. ### 1/5 — Pilot *2012-11-19, version 1.64* Not worth the money - very disapointed! In fact I would like my money back! ### 1/5 — Not open *2012-09-03* Why you did not reply me, Pls check App,can't open ### 1/5 — Limited detail *2012-09-02, version 1.64* Unlike the Bill Bufler guide this app does not describe associated faults, or follow a path to a full resolution in problem solving. It is merely an expanded QRH with pictures. You only need to look at Transfer bus off to notice all the missing elements. ### 4/5 — A Unique Reference Guide *2012-08-22* This is a unique reference guide- iPhone users might find the initial cockpit panels hard to read but if you're familiar with the 737, you will have a good understanding of the layout. It works well on an iPad. Lots of good information- I recommend this for pilots who already have a basic system knowledge- great for review ### 1/5 — Nice Concept *2012-07-22* I like the idea of this app, however lacking on the information side of things, I expected more from Billy Bufler. ### 1/5 — Mr *2012-07-11* Waste of money, no useful information, states the obvious. ### 5/5 — 737 Capt. *2012-06-28* I find this to be a very good product for an initial outing. It is crisp and very well presented. I am very much looking forward to your Cockpit Companion in this new format. I am currently using this on an iPhone 4. It will be all that much better on an iPad. Go Bill Go - I've appreciated your work for many years in the old format. ## Frequently asked questions about B737 Alerts ### What Boeing 737 models does B737 Alerts cover?
