Innovative Solutions & Support (IS&S) introduced the Prodigy 3ATI Integrated Standby Unit (ISU) this week at AEA 2025. The ISU is a direct form, fit, and function replacement for legacy standby systems, according to the Exton, Pennsylvania-based avionics manufacturer. IS&S said the Prodigy ISU is available now for commercial, business, and military aviation applications.
With a familiar primary flight display format, the Prodigy ISU provides critical flight information, including altitude, attitude, airspeed, slip/skid, and navigation on an LED-backlit LCD display with direct sunlight readability. Attitude and heading information is derived from a built-in inertial measurement unit. An optional air data module enables the ISU to independently calculate altitude, airspeed, and Mach number. For variable lighting conditions, the ISU’s ambient light sensor adjusts display brightness. 
With certification to DO-160G and RTCA DO-178C Level A standards, the Prodigy ISU includes a directional gyro mode and offers internal and external magnetometer interfaces. The ISU also has an optional autothrottle control capability and configurable options such as night-vision goggle compatibility and standby radio management.
