Hey, it's a VERY complicated business to visit the CPO in Guam.. I'm not exaggerating. I was detained and was going to be arrested by the Guam airport police for going in to the CPO to do CBTs and then trying to come back out without leaving on a flight. I was TDY to Guam at the time and didn't have a local SIDA access badge, just as you won't either. It's complicated because inside security at the Guam airport is also in an international terminal and DHS Secure Area. Even Guam based pilots arriving from a trip CANNOT go to the CPO right there in the terminal to drop off a flight bag because they haven't cleared customs & immigration yet. So, best bet is to call the CPO and arrange to meet Pierre outside of security or ask if you can meet him at the gate of your outbound flight. Believe me, it's a complicated arrangement and the airport police do not like people to try and work around their rules. I'm not the only pilot who has been detained & nearly arrested. My detention lasted about an hour & a half. Not fun. Respond with some way for me to pm you if you want more info. Have a blast on your TDY!
