CDU hidden fire page

[Pantu]

Hi Fellow Simmers,

may be you already discovered the CDU hidden "Instructor" page I came across  inadvertedly today. Haven´t spotted any kind of hint or docs in this respect though yet.
But for all who never saw it before  here´s how to get there:

1.) Press CDU button "Menu" twice
2.) Press "Extras"
3.) Press LSK 3 ( not defined key above Fuel)
Here you are on the page "Instructor"
From here you can trigger APUfire etc.

Think it´s good to know.
May be we should tell PM. Could well be they don´t know it either 

Best regards

Pete
