Airbus profile : upper engine display and lower engine display.

When switchin On "seat belt" and "no smoking", it should appear in the upper
display. How to do that.

Same thing for all messages in the upper display like "APU available",
"Speedbreak", "autobreak", ....

Do you plan to have that in the next build ? Or is it already implemented and
do I have to write it in the code ? (How to ?)
