A-86-114
NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ESTABLISH SPECIFIC REQUIREMENTS FOR THE PLACEMENT OF NIGHTTIME VISIBILITY MARKERS AT AIRPORTS WHERE PREEXISTING MARKERS ARE NOT AVAILABLE AND TRANSMISSOMETERS ARE NOT UTILIZED WITH SPECIAL CONSIDERATION FOR ACCURATELY MEASURING THE SURFACE VISIBILITY IN THE VICINITY OF THE APPROACH END OF INSTRUMENT RUNWAYS TO ASSURE THAT THE PUBLISHED VISIBILITY MINIMUMS FOR AN AIRPORT ARE MET.
In plain language (FlightFinder summary)
The FAA is asked to create specific requirements for placing nighttime visibility markers at airports that lack existing markers and do not use transmissometers, focusing on accurately measuring surface visibility near the approach end of instrument runways to ensure the airport meets its published visibility minimums.
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.
