NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN OPERATIONS ALERT BULLETIN TO REQUIRE PRINCIPAL OPERATIONS INSPECTORS TO REQUIRE THAT AIR CARRIER TRAINING PROGRAMS ADEQUATELY COVER THE EFFECTS OF AIRCRAFT LEADING EDGE CONTAMINATION ON AERODYNAMIC PERFORMANCE, PARTICULARLY AS IT AFFECTS THE RELATIONSHIP BETWEEN AIRSPEED AND ANGLE OF ATTACK AND THOSE FUNCTIONS WHOSE ACTIVATION IS DEPENDENT ON THE ANGLE OF ATTACK, SUCH AS STALL WARNING SYSTEMS AND AUTOTHROTTLE SPEED COMMAND SYSTEMS.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to issue an operations alert bulletin that would require principal operations inspectors to mandate air carrier training programs cover the aerodynamic effects of leading edge contamination, particularly how it alters the relationship between airspeed and angle of attack and affects systems like stall warning and autothrottle speed command that rely on angle of attack.
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.
