The code changes in `aviation_parser.go` modify the `NewBodyParser` constructor to accept a `body` parameter. This allows for the initialization of `BodyParser` instances with a specific body value, improving flexibility and testability. The `body` parameter is now stored in the `body` field of the `BodyParser` struct. This change enhances the overall functionality and maintainability of the code.
