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.
Calibrated airspeed (CAS) is the IAS corrected for instrument and position error . An aircraft's indicated airspeed in knots is typically abbreviated KIAS for  Knots -Indicated Air Speed (vs. KCAS for calibrated airspeed and KTAS for true airspeed ). The IAS is an imp Express yourself. Organize your knowledge. Expand your mind. Discover the world.
Flight levels solve this problem by defining altitudes based on a standard air pressure at sea-level. All aircraft operating on flight levels calibrate to this setting regardless of the actual sea level pressure.istorically, altitude has been measured using a pressure altimeter, which is essentially a calibrated barometer. An altimeter measures air pressure, which decreases with increasing altitude following the barometric formula, and from the surrounding's pressure calculates and displays the corresponding altitude.
