Chapter 10: Engine Maintenance & Operation › Turbine Engine Operation › Checking Takeoff Thrust
precise thrust checking, the aircraft should be stationary, and stable engine operation should be established. If it is needed for calculating thrust during an engine trim check, turbine discharge pressure (Pt7) is also shown on these curves. Appropriate manuals should ... model engine. Engine trimming procedure is also covered in Chapter 2, Engine Fuel & Fuel Metering Systems. The engine pressure ratio computed from the thrust setting curve represents thrust or a lower thrust call part power thrust used for testing…

Chapter 10: Aircraft Systems › Thermocouple Temperature Indicators › Turbine Gas Temperature Indicating Systems
analog turbine inlet temperature indicating system. The over-temperature warning light in the indicator illuminates when the TIT reaches a predetermined limit. An external test switch is usually installed so that over-temperature warning lights for all the engines ... tested at the same time. When the test switch is operated, an over-temperature signal is simulated in each indicator temperature control bridge circuit. Digital flight deck instrumentation systems need not employ resistance-type indicators and adjusted servo-driven thermocouple…

command professional development program is accomplishing its objectives. (2) The aircraft is a multiengine airplane or a single-engine turbine-powered airplane. The aircraft must have an independent set of controls for a second pilot flightcrew member, which ... also have the following equipment and independent instrumentation for a second pilot: (i) An airspeed indicator; (ii) Sensitive altimeter adjustable for barometric pressure; (iii) Gyroscopic bank and pitch indicator; (iv) Gyroscopic rate-of-turn indicator combined with an integral slip…
