Narrative:

We took off on runway 6 at isp with 1/4 mi visibility and adequate visibility to runway references. The RVR at touchdown was 1400 ft and rollout was 3000 ft. We did not get the RVR information from the ATIS, but got it just as we were to take the runway from tower. It did not dawn on us at the time that RVR was controling until after takeoff. We required 1600 ft RVR or 1/4 mi. I think contributing factors were, we were finishing before takeoff checks at the time, concentrating on them. We were also given this information just prior to takeoff, and were not prepared for that. We just heard the 1/4 mi, that is what we needed, we thought, and went. If we took the time to really think about the situation, or had time at the gate to prepare for the RVR, we could have requested runway 24 (the winds were calm) and been just fine since touchdown would have been 3000 ft RVR (controling) and rollout (advisory) would have been 1400 ft RVR.

Original NASA ASRS Text

Title: A CL700 FLT CREW TKOF IS LESS THAN REQUIRED MINIMUMS.

Narrative: WE TOOK OFF ON RWY 6 AT ISP WITH 1/4 MI VISIBILITY AND ADEQUATE VISIBILITY TO RWY REFS. THE RVR AT TOUCHDOWN WAS 1400 FT AND ROLLOUT WAS 3000 FT. WE DID NOT GET THE RVR INFO FROM THE ATIS, BUT GOT IT JUST AS WE WERE TO TAKE THE RWY FROM TWR. IT DID NOT DAWN ON US AT THE TIME THAT RVR WAS CTLING UNTIL AFTER TKOF. WE REQUIRED 1600 FT RVR OR 1/4 MI. I THINK CONTRIBUTING FACTORS WERE, WE WERE FINISHING BEFORE TKOF CHKS AT THE TIME, CONCENTRATING ON THEM. WE WERE ALSO GIVEN THIS INFO JUST PRIOR TO TKOF, AND WERE NOT PREPARED FOR THAT. WE JUST HEARD THE 1/4 MI, THAT IS WHAT WE NEEDED, WE THOUGHT, AND WENT. IF WE TOOK THE TIME TO REALLY THINK ABOUT THE SIT, OR HAD TIME AT THE GATE TO PREPARE FOR THE RVR, WE COULD HAVE REQUESTED RWY 24 (THE WINDS WERE CALM) AND BEEN JUST FINE SINCE TOUCHDOWN WOULD HAVE BEEN 3000 FT RVR (CTLING) AND ROLLOUT (ADVISORY) WOULD HAVE BEEN 1400 FT RVR.
