â¢ In hibernation, the computer completely turns off while, on standby (or sleep mode), computer is at a minimal power consuming state where the memory elements are consuming power. â¢ In hibernation, an image of the memory is saved to the hard drive while, on standby, the memory is retained.
Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator (ASI) on an aircraft, driven by the pitot-static system . It uses the difference between total pressure and static pressure, provided by that system, to either mechanically or electronically measure dynamic pressure.
However, the in-flight entertainment system indicated a ground speed of over 700 mph (1,125 km/h). According to the equation shown above, the plane must have encountered a tailwind of at least 140 mph (225 km/h) to make up the difference.
