The MAS is designed to start aircraft engines equipped with turbine starters. It can also be used for limited air conditioning, de-icing and checking auxiliary systems.
The compressor delivers a continuous non-pulsating flow of warm, completely oil-free and surge-free compressed air, for driving the small high speed turbine starter geared to each jet or turbo-prop engine, the continuous air flow ensuring against mis-starts. As the air is heated by the compression itself, efficient starting is obtained without using a combustion heat exchanger. The oil-free air eliminates fine hazards. For de-icing, the standard connections and outlets of the aircraft are used.
The MAS 6 can also be used for most of the aircraft ground checks; the capacity is sufficient for motoring the engines, thus facilitating these checks.
