NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: EVALUATE A PROCEDURE TO USE THE MAXIMUM ROTATION SPEED DURING TAKEOFF THAT WILL RETAIN THE PRESENTLY REQUIRED END OF RUNWAY AND CLIMB GRADIENT SAFETY MARGINS WHEN OPERATING ON RUNWAYS THAT EXCEED THE MINIMUM TAKEOFF RUNWAY LENGTH REQUIRED; REQUIRE OPERATORS TO PROVIDE MAXIMUM ROTATION SPEED INFORMATION TO DC-9 SERIES 10 FLIGHTCREWS FOR USE IN WINTER OPERATIONS.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to evaluate a procedure for using maximum rotation speed during takeoff that preserves existing end-of-runway and climb gradient safety margins on runways longer than the minimum required length. Additionally, the FAA must require operators to provide maximum rotation speed information to DC-9 Series 10 flightcrews for use in winter operations.
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.
