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.
Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it. Winds at other angles to the heading will have components of either headwind or tailwind as well as a crosswind component.
