A-82-165
NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: AMEND 14 CFR 25.109 AND 14 CFR 25.125 TO REQUIRE THAT MANUFACTURERS OF TRANSPORT CATEGORY AIRPLANES PROVIDE DATA EXTRAPOLATED FROM DEMONSTRATED DRY RUNWAY PERFORMANCE REGARDING THE STOPPING PERFORMANCE OF THE AIRPLANE ON SURFACES HAVING LOW FRICTION COEFFICIENTS REPRESENTATIVE OF WET AND ICY RUNWAYS AND ASSURE THAT SUCH DATA GIVE PROPER CONSIDERATION TO PILOT REACTION TIMES AND BRAKE ANTISKID CONTROL SYSTEM PERFORMANCE. (Supersedes Safety Recommendations A-74-119 through -121 and A-76-136 and -137)
In plain language (FlightFinder summary)
The NTSB asks the Federal Aviation Administration to update two sections of its regulations (14 CFR 25.109 and 14 CFR 25.125) so that transport-category airplane manufacturers must provide stopping-performance data extrapolated from dry-runway tests to represent runways with low friction coefficients, such as wet and icy surfaces. This data must properly account for pilot reaction times and the performance of the brake antiskid control system.
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.
