NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: REQUIRE THAT THE BOEING COMMERCIAL AIRPLANE GROUP MODIFY THE CREW ALERTING SYSTEM OF THE BOEING 757/767 TO INCLUDE A "CAUTION" ALERT TO NOTIFY PILOTS WHEN A MALFUNCTION IN THE AIR/GROUND LOGIC CIRCUITRY HAS OCCURRED THAT WILL RENDER CERTAIN BRAKING SYSTEMS INOPERATIVE UPON TOUCHDOWN. THE ALERT SHOULD ALSO SPECIFY WHICH SYSTEMS (THRUST REVERSERS, GROUND SPOILERS, ANTI-SKID, ETC,) WILL NOT FUNCTION PROPERLY ON LANDING.
In plain language (FlightFinder summary)
The NTSB asks the FAA to require Boeing to add a 'caution' alert to the 757/767 crew alerting system. This alert would notify pilots when a malfunction in the air/ground logic circuitry occurs, rendering certain braking systems inoperative upon landing. The alert should also specify which systems, such as thrust reversers, ground spoilers, or anti-skid, will not function properly.
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.
