ABSTRACT:
An automatic tuning system for controlling the avionics in an aircraft includes an operator actuated keyboard for entering any available frequency for the many avionic receiver/transmitters and/or transponders employed in the aircraft. Signals from the keyboard are applied to a microprocessor programmed to detect first a valid frequency selection for one of the instruments aboard the aircraft and provide control output signals which are converted to a data format for tuning the device to which the selected frequency applies to the frequency selected. Such a system eliminates the need for the pilot or other operator to individually tune a particular device since it is necessary only to enter a desired frequency with a control signal being automatically applied to tune the electronic unit to which the selected frequency corresponds.
