NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require manufacturers of all turbine-engine driven airplanes (including the EMB-120) to provide minimum maneuvering airspeed information for all airplane configurations, phases, and conditions of flight (icing and nonicing conditions); minimum airspeeds also should take into consideration the effects of various types, amounts, locations of ice accumulation, including thin amounts of very rough ice, ice accumulated in supercooled large droplet icing conditions, and tailpane icing.
In plain language (FlightFinder summary)
The Federal Aviation Administration is directed to mandate that manufacturers of all turbine-engine driven airplanes, including the EMB-120, supply minimum maneuvering airspeed data for every flight configuration, phase, and condition (both icing and non-icing). These minimum speeds must account for the impacts of different ice types, amounts, and locations, such as rough ice, supercooled large droplet icing, and tailplane ice.
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.
