When using the RTWR Duenna, I am supposed to post both the jpg image and the text file. Why do both?
A. The jpg image summarizes the main validation points and serves as a graphic marker of the leg’s advance. The text file contains much more technical information that may be useful should any questions arise about the flight’s validity. The text file will be especially important if the pilot thinks that the leg should be valid but the Duenna indicates otherwise. (Sometimes this happens. The Duenna is terrific, but it is not infallible.
