Low visibility taxi operations.

Bottom line

Pilots and aircraft operators should be constantly aware that during certain low visibility conditions the movement of aircraft and vehicles on airports may not be visible to the tower controller. During low visibility operations, brief the requirements and special considerations such as the low visibility taxi chart, if published for the airport, and be alert if ATC states to hold short of the ILS critical area line. When low visibility conditions exist, pilots should focus their entire attention on the safe operation of the aircraft while it is moving.
