I was more thinking about the experience the team has in writing complex
in-aircraft UIs using Canvas.  From what little I know of the G1000, it has
multiple pages of data with data entry for flightplans etc.  I'm sure there is
a lot that has been learned by the Shuttle team that can be passed on
as "best practise".

The Route Manager should be able to handle most of the "magenta line"
tasks, but it may be that the more complicated routing such as the RF
approach, fly-by vs fly-over requires some new autopilot coding as you
describe.
