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.

Useful but limited.

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.

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.

This App shows great potential, but needs a lot more work. It refers to the MEL, but so far none of the failures that I've tried have any MEL consequences (just not the case in real life). So please get the updates going and maybe expand the technical a bit?
Standing by for the improvements.!!
Any chance of placing the associated QRH actions with the snag?
And if you could integrate it with the Cockpit Companion, then it really would be a GREAT App!!!
