omnibearing selector[′äm·nə‚ber·iŋ si′lek·tər]
A device capable of being set manually to any desired omnibearing, or its reciprocal, to control a course-line deviation indicator. Also known as radial selector.
A selector that permits an operator to select the VOR (very high frequency omnidirectional radio-range) bearing on which he or she wishes to approach or leave the station. Any discrepancy between the actual VOR bearing and the bearing produces an error signal, which is fed to the autopilot or deviation indicator, allowing the aircraft to thereafter be guided onto the selected radial. See omnibearing indicator.
