The SA-200 Altitude Pre-Selector is a user friendly system that allows the pilot to pre-select the altitude target and uses the barometric adjustment data from a digital encoding altimeter for extremely accurate altitude capture.
The SA-200 Altitude Pre-Selector enables the pilot to preselect altitude. In addition, the pilot will receive both aural (tone and voice) and visual (LED) alert indications relative to the selected altitude.
The Altitude Selector/Alerter is a single, panel-mounted unit that contains the display, the operating switches, and the computer. The system interfaces with encoding altimeters that provide a standard 100 ft. increment altitude output and baro adjustment output. The unit also works with encoding altimeters that output baro corrected altitude via an RS-422 digital interface or EFIS system. Operation of the Altitude Selector/Alerter with a Cobham autopilot is easy and straightforward.
