Controls and instrumentation - INTRODUCTION

1. The  controls  of  the  gas  turbine  engine  are designed to remove, as far as possible, work load from the pilot while still allowing him ultimate control of the engine. To achieve this, the fuel flow is auto-matically controlled after the pilot has made the initial power selection (Part 10).
2. All engine parameters require monitoring and instrumentation is provided to inform the pilot of the correct functioning of the various engine systems and to warn of any impending failure. Should any of the automatic governors fail, the engine can be manually controlled by the pilot selecting the desired thrust setting and monitoring the instruments to maintain the engine within the relevant operating limitations.
3. The multitude of dials and gauges on the pilot's instrument panel may be replaced by one or a number of cathode ray tubes to display engine parameters.  These are small screens capable of displaying all of the information necessary to operate the engine safely.
