  • Chapter 15: Transition to Turbopropeller-Powered Airplanes › Operational Considerations

    second consideration for transitioning pilots concerns turbine engine heat sensitivity. A turbine engine cannot tolerate an over temperature condition for more than a very seconds without experiencing serious damage. Engine temperatures get hotter during starting than at any other time ... part of the pilot remain crucial until the engine is running at a stable speed. Successful engine starting depends on assuring the correct minimum battery voltage before initiating start or employing a ground power unit (GPU) of adequate output. After…

    taxiway or runway. Note that at night, the Emergency Stop signal is used for all stop indications . Engine Starting Airplane engines vary substantially and specific procedures for engine starting should be accomplished in reference to the approved engine start checklist ... AFM/POH. However, some generally accepted hazard mitigation practices and procedures are outlined in this section. Prior to engine start, the pilot needs to ensure that the ramp area surrounding the airplane is clear of persons, equipment, and other hazards that…

  • Chapter 7: Aircraft Systems › Starting System

    starter engages the aircraft flywheel, rotating the engine at a speed that allows the engine to start and maintain operation. Electrical power for starting is usually supplied by an onboard battery, but can also be supplied by external power through ... starter switch draw current from the main bus bar, but the starter will not operate until the starting solenoid is energized by the starter switch being turned to the “start” position. When the starter switch is released from the “start…

  • Chapter 17: Transition to Light Sport Airplanes (LSA) › Flight Environment › Before Start and Starting Engine

    Before Start and Starting Engine Once a pilot has completed the preflight inspection of the LSA, the pilot should properly seat themselves in the airplane ensuring that the rudder pedals can be exercised with full-range movement without over-reaching ... Seat belts should be checked for proper position and security. The pilot should continue to use the POH checklists. Starting newer generation LSA engines can be quite simple and only require the pull of the choke and a twist…

  • Chapter 10: Engine Maintenance & Operation › Turbine Engine Operation

    Engine Oil Pressure Indicator To guard against engine failure resulting from inadequate lubrication and cooling of the various engine parts, the oil supply to critical areas must be monitored. The oil pressure indicator usually shows the engine oil pump discharge ... should be consulted before attempting to start and operate any turbine engine. A turbofan engine has only one power control lever. Adjusting the power lever, or throttle lever, sets up a thrust condition for which the fuel control meters fuel…

  • Chapter 1: Safety, Ground Operations, & Servicing › Ground Movement of Aircraft › Turboprop Engines

    fireguard must observe all safety practices at all times while standing by during the starting procedure. Turboprop Engines The starting of any turbine engine consists of three steps that must be carried out in the correct sequence. The starter turns ... engaged next. As the engine accelerates, it reaches a self-sustaining speed and the starter is disengaged. The various covers protecting the aircraft must be removed. Carefully inspect the engine exhaust areas for the presence of fuel or oil. Make…
