Hi all, 
My apologies if this is hidden somewhere here, but I was wondering if somewhere it would be possible to edit the code and restrict usage on aircraft depending on your pilot rank. Without this, I don't see much point to even having pilot ranks available aside from the pretty badge you get to wear.   
For example, I've got two ranks; First Officer and Second Officer. I would only like the FO's to be able to operate the 737's in our fleet, while I would like the SO's to be able to operate the 737's and 747's.  
Any way this would be possible or am I missing something? 
Cheers, 
Austin.
