Bombardier is pleased to announce that the new version 3 of its very popular Bombardier Flight Deck app is now available. It is a complete refactoring of the app, with many new and exciting capabilities. The new version allows you to: - Organize your documents for rapid access using tags, color-codes and favorites - Swipe to the left any document title to tag it, color-code it or mark it as a favorite - Visually search for documents with the new automatic thumbnail feature - Select files easily on smaller devices with large icon view - Annotate your documents with ink, highlighter, text, notes, photos or add a signature in one touch - Select your favorite day and night time theme - Support GDPR privacy legislation - Read PDF files easily and intuitively with one touch full-screen mode and thumbnail page view - Display Supporting Documents - Runs on iPhone Note to flight crews: 1. When you first install this application you MUST press the SYNC icon, which will resync all of your existing files to support the new file formats in this version. Make sure you allow yourself some time for this. 2. After syncing, pilots MUST take the time to read the Version 3.0 Pilot Training publication included on their account when using this version as an EFB as several of the icons have changed location. If you do not have this publication assigned to your device, contact flightdeckapp@aero.bombardier.com. 3. When clicking hyperlinks in a document, note that the hyperlink button has been moved to the navigation pane. 4. Check with your local authority for regulatory compliance of the new Bombardier Flight Deck app version 3 before deleting the previous version 2. ------------------------- Bringing Paperless¹ Efficiency to Pilots No more carrying pounds of aircraft manuals and documents on-board. No more waiting for Temporary Revision (TR) updates. With the Bombardier Flight Deck* application, Bombardier* aircraft pilots can enjoy the benefits of going paperless¹ by being able to store and access manual data and other documentation instantly from their iPad® - without Wi-Fi. No other solution combines automatic TR updates, user control of content and aircraft serial number-specific information into one application. Bombardier Flight Deck* also includes all required FAA, EASA and TC compliant audit trails for paperless¹ operations. All documents. All accessible. All in one Place. Fast and easy, you can drag and drop electronic versions of aircraft documents, manuals and forms into online folders. Pilots simply enter a license code, then push a sync button on the iPad® and the updated documents are automatically downloaded and cataloged. In less time than it takes to send a fax, pilots can sign documents, add text and email it to the fleet manager. Automatic Revision Updates No more manually inserting revisions or Temporary Revisions (TRs) into Bombardier’s flight manuals. These are automatically inserted into the correct sections and distributed across every iPad® in the operator’s fleet by Bombardier Technical Publications. Valuable time is saved and pilots are always ready to fly in accordance with the latest regulatory requirements. ¹ Paperless refers to the process identified in the relevant airworthiness requirement pertaining to paperless cockpits, including but not limited to FAA-AC-91-78. Use of the Bombardier Flight Deck* application does not relieve operator and its flight crew of their responsibility to comply with the applicable airworthiness authority approved documents.
