Narrative:
When I studied the operating manual I read about the company's takeoff minimums and departure minimums. The takeoff minimums in some cases are less than standard. En route I listened to ATIS prior to my approach to maf. It said 1600' RVR and 0' ceiling. Somehow I mixed up my takeoff and my departure minimums and instead of 2400' RVR that is needed to even start the approach I began the approach at 1600' RVR. Approach controller said, 'cleared for ILS runway 10. RVR now is reported 1500. That's right at minimum, isn't it?', and that even made me more sure of my minimum. I replied, 'cleared for runway 10 ILS and that's right at minimum,' and began my approach. I saw the rabbit at 200' AGL. Runway threshold lights at 100' AGL. I landed, parked. No more was said until my fellow pilot told me I busted minimums. I got the manual out and studied it again and found out he was right. Lesson learned and action to avoid such a problem in future is to study your manual even more carefully and make sure you understand fully before entering IFR conditions with probably low minimums.

Title: ATX SMT MADE AN ILS APCH TO MAF USING TKOF RVR INSTEAD OF LNDG RVR AS ARPT MINIMUMS FOR LNDG.
Narrative: WHEN I STUDIED THE OPERATING MANUAL I READ ABOUT THE COMPANY'S TKOF MINIMUMS AND DEP MINIMUMS. THE TKOF MINIMUMS IN SOME CASES ARE LESS THAN STANDARD. ENRTE I LISTENED TO ATIS PRIOR TO MY APCH TO MAF. IT SAID 1600' RVR AND 0' CEILING. SOMEHOW I MIXED UP MY TKOF AND MY DEP MINIMUMS AND INSTEAD OF 2400' RVR THAT IS NEEDED TO EVEN START THE APCH I BEGAN THE APCH AT 1600' RVR. APCH CTLR SAID, 'CLRED FOR ILS RWY 10. RVR NOW IS RPTED 1500. THAT'S RIGHT AT MINIMUM, ISN'T IT?', AND THAT EVEN MADE ME MORE SURE OF MY MINIMUM. I REPLIED, 'CLRED FOR RWY 10 ILS AND THAT'S RIGHT AT MINIMUM,' AND BEGAN MY APCH. I SAW THE RABBIT AT 200' AGL. RWY THRESHOLD LIGHTS AT 100' AGL. I LANDED, PARKED. NO MORE WAS SAID UNTIL MY FELLOW PLT TOLD ME I BUSTED MINIMUMS. I GOT THE MANUAL OUT AND STUDIED IT AGAIN AND FOUND OUT HE WAS RIGHT. LESSON LEARNED AND ACTION TO AVOID SUCH A PROB IN FUTURE IS TO STUDY YOUR MANUAL EVEN MORE CAREFULLY AND MAKE SURE YOU UNDERSTAND FULLY BEFORE ENTERING IFR CONDITIONS WITH PROBABLY LOW MINIMUMS.
