The 737 Handbook is an interactive technical guide for pilots which provides a quick reference for sim or interview preparation from initial type rating to command upgrade. The app features interactive schematics, photos and videos with unique content. The information is sorted in different levels from most essential information on the page to in-depth information in pop-up windows. This enables you to choose the way you want to learn. Should you require quick reference you can go through the main text in the chapter. Should you, however, wish to explore the systems more in-depth you can do so by opening different pop-up windows, text and playing around with fully interactive schematics. Try it out yourself! Main features: * 226 pages divided into 18 chapters * Over 20 videos of different engine malfunctions and various systems operation * FMC simulator with CPDLC and ACARS * Fully Interactive schematics including Electrical, Fuel, Air Systems and many more * 737 Flight Deck Mock-up * Photo galleries * News section with technical blog posts * All of the content is available offline when online the app checks for content updates Note: The 737 Handbook comes with one chapter and one interactive schematic for free. The rest of the content is available as one time in-app purchase. ——————————————————————————— Terms & Conditions In-App Purchases * The 737 Handbook application offers an “in-app” purchase option which will unlock features listed on the “Unlock Premium Access” page * The “in-app” purchase is valid only on the ecosystem where the “in-app” purchase was made (no cross-platform support) * The “in-app” purchase will unlock premium access on all devices within the ecosystem, provided that the devices are signed in under the same ID * All amounts are payable and charged: * (i) for career pass (lifetime subscription) at the time you place your order * (ii) for type rating pass (6 monthly subscription), at the beginning of the subscription and, because each such subscription renews automatically for an additional period equal in length to the expiring subscription term until you cancel it, at the time of each renewal until you cancel. * You must cancel your subscription before it renews to avoid the billing of the fees for the next subscription period * Your subscription will automatically renew unless auto-renew is turned off at least 24-hours before the end of the current subscription period. * Your account will be charged for renewal within 24-hours prior to the end of the current subscription period.

Avionics Pro contains virtually every tool needed to quickly solve homework problems and preview electronic lab experiments for the student who is completing a course of study to become an Aircraft Electronics Technician (AET). Specifically, it emphasizes Introductory Aircraft Avionics, featuring real world circuits that have been tested using an industry standard circuit simulator (Multisim) as well as in an actual electronics lab environment. Beyond the AET course, Avionics Pro is a handy refresher for graduate technicians in the industry as well as students looking to expand their understanding through higher education engineering courses. Avionics Pro features graphics support for all standard Apple phones and iPads.
