NTSB Safety Recommendation — Aviation
Recommendation text
THE FEDERAL AVIATION ADMINISTRATION, TOGETHER WITH THE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION, CONDUCT FURTHER STUDY, INCLUDING OPERATIONAL FLIGHT TESTS, OF THE RELATIVE EFFECTIVENESS BETWEEN THE CURRENT, MOST WIDELY UTILIZED STALL WARNING DEVICES (HORNS, LIGHTS, ETC.) AND THE SO-CALLED IMPROVED STALL WARNING EQUIPMENT, E.G., ANGLE-OF-ATTACK INDICATORS, STICK-SHAKERS, ETC., AS FOUND IN SOME OF THE MORE SOPHISTICATED GENERAL AVIATION AIRCRAFT.
In plain language (FlightFinder summary)
The Federal Aviation Administration and the National Aeronautics and Space Administration are jointly asked to conduct further study, including operational flight tests, to compare the effectiveness of currently widespread stall warning devices (such as horns and lights) with improved stall warning equipment like angle-of-attack indicators and stick-shakers found in more sophisticated general aviation aircraft.
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.
