  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 ... external power receptacle. When the battery switch is turned on, electricity is supplied to the main power bus bar through the battery solenoid. Both the starter and the starter switch draw current from the main bus bar, but the starter…

  However, in a helicopter they are not. Because of the greater weight of a rotor in relation to the power of the engine, as compared to the weight of a propeller and the power in an airplane, the rotor must ... disconnected from the engine when the starter is engaged. A clutch allows the engine to be started and then gradually pick up the load of the rotor. Figure 4-20. The main rotor transmission reduces engine output rpm to optimum…

  Engine Start and Rotor Engagement During the engine start, rotor engagement, and systems ground check, use the manufacturer’s checklists. If a problem arises, have it checked before continuing. Prior to performing these tasks, however, make sure the area around ... rotor blades so that they are not aligned with the fuselage. This may prevent the engine from being started with the blades still fastened. For a two-bladed rotor system, position the blades so that they are perpendicular…

  properly conducted. Pilots should remain at the flight controls; and refueling personnel should be knowledgeable about the proper refueling procedures and properly briefed for specific helicopter makes and models. The pilot may need to train the refueling personnel on proper ... refueling procedures for that specific helicopter. The pilot should explain communication signs or calls, normal servicing procedures, and emergency procedures as a minimum. At all times during the refueling process, the pilot should remain vigilant and ready to immediately shut…

  Limitations The powerplant limitations area describes operating limitations on the helicopter’s engine including such items as rpm range, power limitations, operating temperatures, and fuel and oil requirements. Most turbine engines and some reciprocating engines have a maximum power ... maximum continuous power rating. The “maximum power” rating is the maximum power the engine can generate and is usually limited by time. The maximum power range is depicted by a yellow arc on the engine power instruments, with…

If a full touchdown is to be practiced, it is common technique ... move the power levers to the idle position once the landing area can safely be reached. In most helicopters, the pilot is fully committed at that point to make a power-off landing. However, it may be possible to make…
