NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Work with Title 14 Code of Federal Regulations Part 135 certificate holders that operate under visual flight rules in the aircraft’s required terrain awareness and warning system (TAWS) class to (1) ensure that management and pilots are aware of the risks associated with distraction (from continuous nuisance alerts) and complacency (brought about by routine use of the terrain inhibit feature); (2) develop plans for mitigating those risks and minimizing nuisance alerts; and (3) develop procedures that specifically address when pilots should test, inhibit, and uninhibit the TAWS alerts, considering the operator’s typical operations and the TAWS manufacturer’s guidance.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to collaborate with certain Part 135 certificate holders operating under visual flight rules to ensure that management and pilots understand the risks of distraction from continuous nuisance alerts and complacency from routine use of the terrain inhibit feature. It must also help them create plans to reduce nuisance alerts and establish procedures for when pilots should test, inhibit, and uninhibit the terrain awareness and warning system (TAWS) alerts, based on the operator's operations and the manufacturer's guidance.
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.
