Abstract: FIELD: aircraft instrumentation engineering; monitoring of gas-turbine engines. 
     SUBSTANCE: proposed onboard monitoring system makes it possible to check aircraft engine working in standard, off-standard and augmented power rating modes. Monitoring is based on information received from sensors and transmitted to inputs of multiplexing unit and from output of this unit to onboard computer. Information received from sensors of very important parameters of aircraft engine is fed directly to command unit input. Present measured parameters pertaining to dangerous magnitudes, viz.: pressure of gas after fan doors, consumption and pressure of fuel and thrust are compared with limiting and dangerous magnitudes in onboard computer and in command unit on basis of computational algorithms introduced in their storage and received from sensors of very important parameters. In case these magnitudes are beyond limiting and dangerous magnitudes, limiting and dangerous commands are formed and are transmitted to onboard computer and to emergency information system of aircraft for recording and warning the crew. Magnitudes of actual operating hours and remaining service life of aircraft engine are determined in onboard computer with the received commands taken into account and are transmitted to onboard information system for recording and indication.
