PLAY1221 Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. This can reduce power use on the aircraft by eliminating the constant draw of the hydraulic pumps. Additionally, the EHA has the advantage that it only draws power when it is being moved, the pressure is maintained internally when the motor stops. Control transfers are the same as in USB 2.0. The system uses a best-effort policy, but software may restrict channel access and available bandwidth for devices. USB flash drives with images of dragons, cats or aliens are very popular in Asia.|This Article Possibly Contains Original Research
