Hello all, 


Wondering if anyone has a great resource for aviation acronyms for our industry.  We have a new hire starting soon that doesn't have any previous flight experience and I'm looking for a list of acronyms for her-more aviation focused.  Any suggestions for websites or lists that someone may already have?  


Much appreciated!
