NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require, on all MD-11's equipped with the flight control computer-908 software, the retrofit of digital flight data recorder systems with all additional parameters required to precisely identify and differentiate between pilot and longitudinal stability augmentation system (LSAS) elevator control activity, including control column force, inertial reference unit pitch rate, LSAS command signals, elevator positions, and automatic ground spoiler command signals.
In plain language (FlightFinder summary)
The FAA is asked to require, on all MD-11 aircraft with flight control computer-908 software, the retrofit of digital flight data recorder systems to include additional parameters that can precisely identify and differentiate between pilot and longitudinal stability augmentation system (LSAS) elevator control activity. The parameters include control column force, inertial reference unit pitch rate, LSAS command signals, elevator positions, and automatic ground spoiler command signals.
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.
