Regulators Set Safety Standards for Electronic Flight Control System
The US Federal Aviation Administration has issued final special conditions for the Gulfstream Aerospace Corporation Model GVII-G400 airplane, addressing a novel design feature in the electronic flight control system. The conditions add safety standards for an envelope protection function that protects the airplane from over- and rapid-rotation on takeoff. This feature, called takeoff stall protection, limits excessive pitch rate and pitch attitude during takeoff. The FAA found that existing airworthiness regulations do not contain adequate safety standards for this feature. The action was reported by AviNews.
