Innovative Solutions & Support (IS&S) has added Beechcraft King Airs equipped with Garmin G1000 and G1000 NXi avionics to its ThrustSense autothrottle supplemental type certificate (STC) program. The move adds a significant number of aircraft to the potential market for the ThrustSense autothrottle and adds the safety benefits of ThrustSense—including LifeGuard engine-out VMCa mitigation—to G1000-equipped King Airs.

The STC covers King Air 200 and 300-series turboprops with G1000 avionics. In addition to the modified throttle quadrant, the STC requires the installation of an IS&S standby instrument, which is a form-fit replacement for the Mid-Continent Standby Attitude Module in the G1000-modified King Airs. The IS&S standby also is the controller for the ThrustSense autothrottle and the pilot interface.
