NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Allow Seattle-Tacoma International Airport, as an interim solution, to apply a) large nonstandard taxiway identification markings (such as the word "TAXIWAY") at regular intervals to the full width of the taxiway T surface, starting near the approach end and continuing for one-half the length of the taxiway; and b) a continuous serpentine line over the taxiway centerline, between each of the aforementioned nonstandard taxiway identification markings.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to permit Seattle-Tacoma International Airport to use two temporary taxiway markings: large nonstandard taxiway identification markings (e.g., the word "TAXIWAY") repeated at regular intervals across the full width of taxiway T for half its length starting near the approach end, and a continuous serpentine line along the taxiway centerline between those markings.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
