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.
where: 1  L is the amount of Lift produced, 2  Ï {\displaystyle \rho } is the air density, 3  V is the true airspeed of the airplane or the Velocity of the airplane, relative to the air. 4  S is the area of the wing.
