Abstract
Avionics apparatus for providing to a pilot readings of temperature, pressure altitude, and density altitude. Sensors provide electrical signals responsive to ambient temperature and pressure, and a functional module operates on signals derived from said sensors to provide signals indicative of the pressure altitude and density altitude. A multiplexer and display respond to a mode selection switch to provide visual readouts of temperature in degrees Fahrenheit and in degrees Celsius, and altitude.
