I fly single engine planes out of an airport which also has regularly scheduled passenger service. There is a sterile area inside the terminal, with TSA screeners and luggage X-rays. In addition, there is also a secure area on the ramp where the passsenger planes load and unload, marked by a red painted boundary and warning signs. For the rest of us GA pilots, the ramps and hangars are in a SIDA ('Security Identification Display Area'), where we need to wear photo ID's to enter. My question is: as a licensed CCW holder, am I allowed to carry concealed in the SIDA? I asked one of the State Troopers who was maintaining airport security, but he didn't know. He said that he thought it was OK, but he couldn't definitely say so. I know that I can carry inside the areas of the terminal that are not sterile, since they are not part of the SIDA, and of course I cannot carry inside the sterile area, but what about the rest of the ramps and hangars? Your opinions are welcome, but please note whether you are stating opinion or facts.
