1. Key to engine diagrams:

1.1 Meaning of the arrows (connections): In order to improve the clarity of the diagrams, any media entering or exiting the engine are indicated by an arrow. Different letters are used to identify different media (e. g. = fuel gas entering). In some cases a digit is added to the letter to give even more detailed information. The tip of the arrow indicates the flow direction of the media.
