Narrative:

After the recent ground collision in detroit, most pilots have been especially vigilant on the ground and pointing out airfields where airport taxiway/runway signs need improvement. One such location is at sea-tac, where lighted taxi/runway signs are way below the norm--especially with the renowned fog conditions at sea-tac. Specifically, when taking off to the north, most aircraft use 34L. Since most aircraft taxi sward (for takeoff north), they must then turn right on B11, hold short of 34R, then cross 34R, taxi on C11 to proceed to 34L. There are presently no taxi signs showing B11 (or B12). In addition, the red 16L/34R runway sign is on the south side of B11, which is very difficult to see since most aircraft hold short of the runway pointed south. An additional 16L/34R red runway sign on the north side of B11 would really be helpful and safety enhancing. The more taxiway/runway signs the better, especially at locations most frequently used. FAA required minimum signs do not create a proper safety margin.

Title: ACR REPORTER IS CRITICAL OF THE LACK OF TXWY SIGNS AND RWY MARKINGS AT SEA.

Narrative: AFTER THE RECENT GND COLLISION IN DETROIT, MOST PLTS HAVE BEEN ESPECIALLY VIGILANT ON THE GND AND POINTING OUT AIRFIELDS WHERE ARPT TXWY/RWY SIGNS NEED IMPROVEMENT. ONE SUCH LOCATION IS AT SEA-TAC, WHERE LIGHTED TAXI/RWY SIGNS ARE WAY BELOW THE NORM--ESPECIALLY WITH THE RENOWNED FOG CONDITIONS AT SEA-TAC. SPECIFICALLY, WHEN TAKING OFF TO THE N, MOST ACFT USE 34L. SINCE MOST ACFT TAXI SWARD (FOR TKOF N), THEY MUST THEN TURN RIGHT ON B11, HOLD SHORT OF 34R, THEN CROSS 34R, TAXI ON C11 TO PROCEED TO 34L. THERE ARE PRESENTLY NO TAXI SIGNS SHOWING B11 (OR B12). IN ADDITION, THE RED 16L/34R RWY SIGN IS ON THE S SIDE OF B11, WHICH IS VERY DIFFICULT TO SEE SINCE MOST ACFT HOLD SHORT OF THE RWY POINTED S. AN ADDITIONAL 16L/34R RED RWY SIGN ON THE N SIDE OF B11 WOULD REALLY BE HELPFUL AND SAFETY ENHANCING. THE MORE TXWY/RWY SIGNS THE BETTER, ESPECIALLY AT LOCATIONS MOST FREQUENTLY USED. FAA REQUIRED MINIMUM SIGNS DO NOT CREATE A PROPER SAFETY MARGIN.
