NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE DOUGLAS AIRCRAFT COMPANY TO PROVIDE DATA NEEDED TO UPGRADE MD-11 TRAINING SIMULATORS TO ACCURATELY REPRESENT THE AIRCRAFT'S LONGITUDINAL STABILITY AND CONTROL CHARACTERISTICS FOR HIGHT ALTITUDE CRUISE FLIGHT; AND TO DEVELOP SPECIFIC GUIDANCE AND SIMULATOR SCENARIOS TO TRAIN PILOTS IN OPTIMUM TECHNIQUES FOR THE RECOVERY FROM HIGH ALTITUDE UPSETS, INCLUDING THOSE ACCOMPANIED BY STALL WARNING.
In plain language (FlightFinder summary)
The NTSB asks the FAA to mandate that Douglas Aircraft Company supply data necessary to update MD-11 flight simulators so they correctly depict the aircraft's pitch stability and control during high-altitude cruise. Additionally, the FAA should produce specific instructions and simulator exercises for teaching pilots the best methods to recover from high-altitude upsets, including those triggering stall warnings.
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.
