I am new to the aviation industry certainly where it comes to running an F.B.O.
I was hoping I could get advice from your community doesn’t matter what subject I’m just looking for anything you believe would help.
A web search would be a good place to start. Mine found this site which defines what a FBO is in the aviation industry: What is an FBO Airport? | Fixed Base Operators and Private Terminals
Hasn’t your hiring manager given you any indication of what your expected duties will be?
