HEIR, GENERAL. Heir at common in the English law. The heir at common law is he who, after his father or ancestor's death has a right to, and is introduced into all his lands, tenements and hereditaments. He must be of the whole blood, not a bastard, alien, &c.
An air data computer (ADC) is a avionics component that assimilates the inputs from an aircraft's external and system sensors and returns a series of calculated results critical to the control of the aircraft. In one compact package, the air data computer performs what a bank of individual instruments were once required to do. Almost all the flight-related information displayed in newer commercial aircraft fitted with glass cockpits is compiled by an air data computer.
Computers produce audio data that requires output devices such as speakers and headphones to deliver the sound to you. Audio data is created by the computer and then sent to the audio card, which is located in an expansion slot. The card translates the data into audio signals, which are sent to the audio output device.
