While the lessons were originally developed around the Diamond aircraft, over the years they have been updated to be more generic and useful to everyone. The limited aircraft specific information remaining has been annotated with a highlighted yellow asterisk for easy recognition and updates. Additionally, we've been adding a number of aircraft specific systems lessons and equipment & malfunctions lessons. Here's what we have so far!
