UNAUTHORIZED TKOF PERFORMED BY ACR LTT WHEN ARPT WX MINS FOR TKOF WERE NOT LEGAL.

Narrative

WE WERE DEPARTING PEORIA; IL; FOR A DIRECT FLT TO MINNEAPOLIS. I AND MY FO HAD RECENTLY COMPLETED A NEW LOWER THAN STANDARD TKOF PROGRAM THE COMPANY HAD JUST IMPLEMENTED ALLOWING US TO TKOF WITH 600 RVR AS LONG AS CERTAIN PROVISIONS WERE MADE. PIA WAS RPTING 600-700 FT RVR ON THE ACTIVE RWY 13/31. THE PROBLEM IS THAT THE NEW COMPANY TRAINING PROC WAS NOT CLR ABOUT THE FACT THERE WERE ADDITIONAL PROC REQUIRED. AS THE NEW PROCS WERE VAGUE; I PREVIOUSLY DISCUSSED THE NEW PROCS WITH THE COMPANY INSTRUCTOR DURING RECURRENT TRAINING AND ALSO WITH THE COMPANY CHK AIRMAN DURING MY RECURRENT CHK RIDE IN A FLT SIMULATOR. AS THE NEW PROCS WERE UNCLR; MY SPECIFIC QUESTION TO BOTH INSTRUCTORS WAS THIS: VERIFY THIS IS CORRECT; WE MAY NOW USE LOWER THAN STANDARD TKOF MINS TO 600 RVR ANYWHERE WE PREVIOUSLY COULD USE LOWER THAN STANDARD TKOF MINS TO 1600 RVR. BOTH INSTRUCTORS CONFIRMED MY ANSWER. THE PROBLEM IS THEY WERE PARTIALLY WRONG IN THAT THERE ARE ADDITIONAL REQUIREMENTS WHICH MUST BE REFED IN THE GOM. THIS WAS NEVER TAUGHT AND NOW THE IL FAA IS INVESTIGATING. I HAVE ENCLOSED A COPY OF THE NEW PROCS WHICH NOW I UNDERSTAND ARE INCOMPLETE.
