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.
True airspeed - Calculating true airspeed. 1  At low speeds and altitudes, IAS and CAS are close to equivalent airspeed (EAS). 2  T A S = E A S Ï 0 Ï , {\displaystyle \mathrm {TAS} =\mathrm {EAS} {\sqrt {\frac {\rho _ {0}} {\rho 3  }}},}. TAS can be calculated as a function of Mach number and static air temperature...
