Czech aerospace company PBS has introduced a new auxiliary power unit (APU) designed for helicopter applications.

The Spark 40 APU can be used aboard medium- and heavy-lift helicopters of up to 10t, according to PBS. The company says it is both lighter and more powerful than the company’s previous APU model.
