The IS&S Model Solid State Barometric Altimeter was developed under a joint Navy/Air Force contract as a plug-in replacement for the AAU-19/-34/-37 standard altimeters. IS&S’ advanced technology is twenty times more reliable and three times more accurate than existing designs. The SSBA combines a smooth mechanical pointer with a high intensity illuminated LCD display for enhanced readability under adverse lighting conditions. Dual mode operation displays CADC altitude information with an internal solid state pressure transducer for backup mode.
