B777 Companion is an independent technical study app for professional pilots on the Boeing 777 family. It is built for classroom use, self-study, type familiarisation, and recurrent preparation — offline-first. Best on iPad; also on iPhone with a compact layout. Study content is organised the way a type-rated pilot works, not as a picture book: • Interactive cockpit panels (overhead, glareshield, instrument, pedestal) with control-level detail • ATA-structured systems study, linked to the same controls and indications • Alert / EICAS study pages • Interactive synoptics and schematics • In these schematics all panels with switches, valves, lights, etc. are functional, including alerts • All EICAS messages can be introduced, and the effect is shown in the schematics • A study FMS / CDU trainer with a limited training database; when online a broader (not operational) database is available Select 777-200, 200ER, 300, 300ER, or 300ER Special Freighter (300ERSF). Engine and unit preferences follow the selected study configuration. 300ERSF is the passenger-to-freighter conversion of the 300ER, and coming soon, also the factory 777F. Created by Teslabs. The owner is an airline captain with more than 34 years of flying experience and thousands of hours on Boeing types including 737, 767, 747, 777, and 787. NOT FOR OPERATIONAL USE. This is not a flight-deck, dispatch, or maintenance tool, not a checklist substitute, and not an official manufacturer or operator product. Names of aircraft types and manufacturers appear for identification and study only. Trademarks remain with their owners. Where this app and approved documentation differ, the current operator-approved manuals for your aircraft always take precedence. ## Key features - Interactive cockpit panels - ATA-structured systems study - Alert/EICAS study pages - Interactive synoptics and schematics - Study FMS/CDU trainer - Multiple 777 model support ## Frequently asked questions about B777Companion ### What is B777Companion?
