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.
tion is sent to the air data computer in one of several forms: analog voltage, synchro format or digitally. The final measurement that must be considered and one that influences many calcula-tions is the air temperature. The total air temperature (TAT) probe is one method while a simple outside air tem-perature (OAT) probe is another.
