I am not a real pilot thus my question is if PA announcement in cargo plane make sense ?

Also i doubt that guys in cargo planes have ladies to serve food and drinks

 

Correct me if i am wrong.

FS2Crew 777 supports the Freighter models, and the FA's cabin announcements, etc., are inop in the freighter version.

 

Correct, you would not make PA's in the freighter.

 

So just don't make them :-)

My flight attendant is so nice that still ofer drinks and food even for cargo drivers
