That’s what you can get confirmed on AoA main website. Their videos explain in great details the systems and operations of airliners brought to flight sim as addons. They also produce in-flight complete tutorials. For the Triple Seven, the training will be found at http://www.777training.com/ and there’s a sample of it on YouTube. With their new website look and policy, the training videos are now only available through live streaming. HD download will require you to pay for it as an option.
