PLT FINDS HIMSELF INSIDE THE AREA DESIGNATED AS A SECURITY AREA AT SAF.

Narrative

I HAD JUST LANDED AT SAF AND WAS TAXIING IN THE RAMP AREA TO PICK UP A PAX. I NOTICED AN ACR NEARBY (APPROX 50 YARDS AWAY) THAT WAS LOADING PAX; BUT DID NOT THINK TWICE ABOUT IT. SHORTLY THEREAFTER; I WAS INFORMED BY THE TWR THAT I WAS IN A SECURITY AREA AND WOULD BE FINED UNLESS I VACATED IT IMMEDIATELY. I LOOKED CLOSER AT THE RAMP AREA AND NOTICED I WAS EVIDENTLY ON THE 'WRONG' SIDE OF A RED LINE. I TAXIED OUT OF THE AREA IMMEDIATELY. EVIDENTLY THE RED LINE DELINEATES A SECURITY AREA WHICH IS ACTIVE WHEN PAX ARE LOADING OR UNLOADING IN IT FROM COMMUTER AIRLINES. DESPITE DOING MUCH OF MY STUDENT TRAINING AT SAF; I WAS NEVER BRIEFED ON THIS. I ASKED SEVERAL LCL PLTS AND INSTRUCTORS IF THEY WERE AWARE OF THE EXISTENCE OF A SECURITY AREA AT SAF. NONE WERE. I COULD ALSO FIND NO MENTION OF IT IN THE AIM OR AFD. THE USE OF A SECURITY AREA FOR COMMERCIAL PAX MAKES PERFECT SENSE; AND; NOW THAT I AM AWARE OF IT; I WILL AVOID IT IN THE FUTURE. HOWEVER; IT WOULD BE MORE EFFECTIVE IF ITS EXISTENCE/PURPOSE WERE PUBLISHED TO LCL PLTS!
