Avionics specialist ISS has developed its ThrustSense “Integrated Autothrottle” offering as the first full-regime autothrottle system for the Beech King Air twin turboprop.
The system, which is already offered as an upgrade for the Pilatus PC-12, is expected to be certificated in 2019 on the King Air 200, with the 300 to follow.
ISS says that in the take-off to landing phases of flight, including go-around, the system allows the pilot to automatically control the power setting of the engine. The autothrottle computes and controls appropriate power levels, thereby reducing pilot workload. It also provides “FADEC-Like engine protection” for the Pratt & Whitney Canada PT6A turboprop engine.
“Interest from King Air operators is very high,” says Tom Grunbeck, ISS director of autothrottle programmes. He adds that the system is priced at $68,000 for the King Air. The system on the PC-12 single is $54,000.
