Safir 5K/G Z8 is an auxiliary power unit designed primarily to supply AC for starting the main engines, as well as to the deck network.

The auxiliary power unit contains all the necessary accessories (the AC generator is currently not supplied standardly) for safe operation and momentary as well as long-term diagnostics of the unit.

The exhaust gas temperature, revolutions and other indicators are constantly monitored. The fuel and oil filter status is also signalled. All data are recorded by the control unit equipped with a RS 422 communication interface. This APU was certified for civil aviation by EASA according to CS-APU, and by CAAC according to TSO-C77b.
