Wind Dancer Aviation Services plans to reintroduce turbo-normalising kits for light aircraft after acquiring supplemental type certificates (STC) covering a range of general aviation types. Turbo-normalising is a performance- improving technique for piston-powered aircraft by turbocharging the engine to maintain its sea-level manifold pressure to higher altitudes and temperatures.

Pagosa Springs, Colorado-based Wind Dancer has acquired 49 STCs for Rajay turbo-normalising kits from Kelly Aerospace Power Systems, which will continue to make the components. The company aims to re-establish product support for existing turbochargers, says president Tylor Hall.

Wind Dancer plans to relaunch improved kits aimed at the conversion market. Turbo-normalising can boost climb rate and increase cruise speed by 20kt (37km/h) or more above 10,000ft (3,000m), he says.

The first kit to be available will be for the Aero Commander piston twin, Hall says.
