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.
Published: January 2014. Popularly known as black boxes, event data recorders (EDRs) have helped investigators solve the mysteries of airplane crashes for decades. Now theyâve become standard in almost every new car sold. Event data recorders track vehicle data such as speed, acceleration, braking, steering, and air-bag deployment before, during, and after a crash. First introduced by General Motors in basic form on air-bag-equipped models in the mid-1970s, EDRs were being used by various manufacturers in 64 percent of all new models by the 2005 model year, according to the National Highway Traffic Safety Administration (NHTSA).
