Introducing Easy E6B - the co-pilot who never takes a day off and certainly never messes up your coffee order. With more aviation calculators than you can shake a control stick at, this app is a ready companion for fledgling feathered fliers and old birds alike. Don your aviator goggles and see what's on offer: Weather calculators so fine-tuned, they're practically divining rods. Cloud base? Check. Freezing level? Check. Crosswind, headwind, and tailwind measurements? Triple check. Hydroplane speeds and pressure & density altitude? We've got you covered better than an airplane under a hangar. Preflight calculators ready to aid you in fuel calculations, compass headings, and flight leg times. They’re as essential to your flight as remembering to close the cockpit door. Because when you're up in the air, "winging it" should not involve fuel requirement calculations. In-flight calculators to handle your altitude, speed, and distance. We've taken the guesswork out of the equation, so you can focus on the task at hand: not making clouds your unplanned landing site. And a full wing-span of conversion calculators for all your aviator needs. We've got temperature, pressure, altitude, and speed conversions that would even make NASA engineers nod approvingly. The flight deck keeps getting better: a night-vision-friendly Night Mode (with automatic switching at local sunset), aircraft profiles backed by a built-in database of popular GA types, live METARs pulled straight into your calculators (with winds converted to magnetic - your runway numbers will approve), a plain-English METAR decoder, Home Screen widgets, and Siri shortcuts for hands-free calculating. Easy E6B - it's intuitive, it's user-friendly, and it's got more brains than a gaggle of ground controllers. So unless you find joy in juggling jet-lag and calculations, why not let us take the load off? Tap that download button faster than you'd hit eject in a tailspin and take control of your flight preparation today. With Easy E6B, you can save the thrill for the sky and leave the ground-level stress behind.

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.
