....and last Question (a very short one this time *g*): I do not understand, what the "Odd" and the "Even" Maps are for => which of the maps is used when? 

 

Hi Etzel,

 

The Odd Map is flown during odd mission weeks (i.e. Week A1, Week A3, Week B1, and Week B3).

 

And the Even Map is flown on even mission weeks (i.e. Week A2, Week A4, Week B2 and Week B4).

 

You can see this progression in the Fall Campaign's schedule.

 

Hope this helps!
