Bill Bulfer's B737 NG Cockpit Companion book series to an iPad app.  It covers the NG, Classics, and the 737 MAX.<br><br>Since 1998, B737 Cockpit Companion has been a valued resource for airline pilots worldwide.  It is a convenient accessible guide to systems, incorporating notes on functionality,  \"theory of operation\", and Bill's extensive experience as a line pilot with a major US carrier.<br><br>B737 Cockpit Companion steps far beyond the \"need to know\" philosophy that is characteristic of modern systems training, and which frustrates many line pilots.<br><br>The app is much more than an \"eBook.\"  At its heart is a powerful database engine that allows a tremendous number of configuration options to be customized without forcing the user to wade through clutter: When you browse a control head,  for instance, you will see only content related to that control head.   <br><br>The app features a touch-based navigation scheme, so you can start with the top-level cockpit view, and find notes specific to the panel you deal with.<br><br>It also contains a number of reference options, so you can look up information without having to work through the control panels.<br><br>The major features include:<br><br>- Extensive coverage of the B737-600, -700, -800, -900, the BBJs, the 737 MAX, and the Classic EFIS/EIS.<br><br>- The complete text of the B737 NG Cockpit Companion print version--and more. <br><br>- All-new, high-resolution graphics detailing every panel and control head.<br><br>- A note-taking capability.<br><br>- The ability to create your own flashcards.<br><br>- An extensive index of over 700 items, linked to the main text.<br><br>- A circuit breaker locator.<br><br>- Bill's high-resolution, vector-based schematics.<br><br>- The content of the B737 Alerts app—a $15 value—optimized for the new database.<br><br>- An extensive glossary.<br><br>- A database update feature to help keep the database up to date (requires a wireless connection).<br><br>Of interest to students or prospective pilots, we also include:<br><br>- A sample Limitations function.<br><br>- A sample Master Minimum Equipment List, based on FAA Rev 55a.<br><br>- An ATA chapter database.<br><br>As with all products of this type, this program is for informational purposes only.  Your FAA-approved company flight manual is the final authority as to the safe and correct operation of your airplane.<br><br>One optional in-app subscription, \"Pro App\", is available.  This includes the text of FMC Guide, Bill Bulfer's book on the Flight Management System; and Quizzer.  This is a convenient way of reviewing systems operation, and was written by Bill.  Pro Pilot also includes a BITE CDU emulator and Airworthiness Directives.  As we add new features, we will be adding them under Pro Pilot.<br><br>• The subscription lasts one year. <br>• Payment will be charged to your iTunes Account at confirmation of purchase<br>• The subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.<br>• Your account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal at the time.<br>• Subscriptions may be managed by you, and auto-renewal may be turned off by going to your iTunes  Account Settings in System Settings after purchase.<br><br>NOTE: The app is generally supported for the current version of iOS, the previous version, and the iPad hardware that supports those versions.<br><br>EULA: http://www.fss.aero/EULA.html","app_summary":"'B737 Cockpit Companion', published by a US-based company and offers in-app purchases at USD 35.99 per item.
