NTSB issues safety recommendations regarding FMS software
9 March 2005

In the light of the March 2003 incident in which a Boeing 747 suffered a tailstrike while the crew tried to rotate the plane at too low a speed, the NTSB issued five safety recommendations. The NTSB advises Honeywell to change the FMS software, a.o. to annunciate warnings to the flight crew when a takeoff reference speed is changed by a value that would impede the airplane’s ability to safely take off.
