To improve the efficiency control the state of a bearings suggested sharing temperature and vibration parameters. Temperature parameters are adjusted taking into account operating conditions of gas turbine engine. Dependence for determining the adjusted values of temperature parameters is received. For control of bearings in vibration parameters it is offered to use the engine stop mode - runout.rn
