FIELD: technological processes.
SUBSTANCE: invention relates to methods for removal of air dissolved in working fluid from hydraulic systems of enclosed-type aircrafts and may be used in development of hydraulic systems. Method includes by-passing of working fluid from serviced hydraulic system of aircraft via cutoff device into hydraulic tank of ground hydraulic installation. In upper part of ground hydraulic installation hydraulic tank, vacuum pump is installed over working fluid, which provides for reduction of pressure in hydraulic tank below atmospheric one.
EFFECT: improved efficiency of removal of air dissolved in working fluid from hydraulic system of enclosed-type aircraft, and also reduction of time required for aircraft preparation for flights.
