I wrote a minor novel on the FE-subject a while ago - Try the "search" function, if you can get it to work.
YouŽll have to be able to read/write in German!
Send an email to the webmaster or your "fleet-specialists" of the workers council at:
http://www.lca-pv.de/
whoŽll hopefully help you out with details of the conditions.

For the destinations of MD11 and B742 see:
http://www.cargo-flugbetrieb.de/routes.htm
The number of the personnel-dep is
+49-6107-777-552 (Mrs Mosandl - the head)
or
+49-6107-777-551 (Mrs Faehrmann)
who should be glad to give you some infos - if youŽre nice and polite etc..
If you donŽt get anything from all of the above please ask again - I just wrote another novel before my pc got "stuck", so IŽve left out some details now.
Good luck!
