A B737 PLT IS CONCERNED THAT THERE ARE CFR EQUIP PLACED ON A TXWY DURING LOW VISIBILITY OPS AT SEA.

Narrative

A NOTE ON THE SEA 20-9 A1 PAGE STATES THAT TXWYS M AND N ARE NOT AVAILABLE WHEN THE RVR IS BELOW 600 FT. THE CHART GIVES NO REASON FOR THE UNAVAILABILITY OF THESE TXWYS. IT IS POSSIBLE THAT IN AN EMER; A PLT MIGHT ATTEMPT TO UTILIZE ONE OF THESE TXWYS THINKING THAT THE REASON THEY ARE NOT AVAILABLE IS DUE TO TAXI FLOW RESTRS DURING LOW VISIBILITY OPS. IN FACT; THE TXWYS ARE NOT AVAILABLE BECAUSE CRASH/FIRE/RESCUE UNITS ARE LOCATED ON THESE TXWYS WHEN THE VISIBILITY IS LESS THAN 600 FT RVR. I WOULD RECOMMEND ADDING THE INFO ABOUT THE VEHICLES ON THE TXWYS TO THE NOTE THAT STATES THEY ARE NOT AVAILABLE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR REVEALED THAT THIS WAS SECOND HAND INFO. THE RPTR HEARD THROUGH A TRAINING CAPT THAT THE PROC FOR LOW VISIBILITY AT SEA WAS TO PLACE CFR EQUIP ON THE CLOSED TXWYS OF M AND N; AND THAT THIS WAS THE REASON THAT THE TXWYS WERE CLOSED. THE REASON FOR THIS WAS EXPLAINED THAT IT WOULD PROVIDE DIRECT ACCESS TO THE RWY IF THERE WERE AN ACCIDENT.
