  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…

  Chapter 4: Helicopter Components, Sections, and Systems › Dual Tachometers › Clutch

  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…

  Power recovery in those helicopters with slower engine response times must have the engines begin to develop enough power to rejoin the needles by approximately 100 feet AGL. If a go-around is to be made, the cyclic control should ... diagram. This is one of the most difficult maneuvers to perform due to the concentration needed when transitioning from powered flight to autorotation and then back again to powered flight. For helicopters equipped with the power control on the collective…

  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…

Signing this recommendation imposes a serious responsibility ... flight instructor. A flight instructor who makes a practical test recommendation for an applicant seeking a certificate or rating should require the applicant to thoroughly demonstrate the knowledge and skill level required for that certificate or rating. This demonstration should…

  Chapter 11: Aircraft Performance › Climb Performance Factors › Region of Reversed Command

  normal command. Flight in the region of reversed command means flight in which a higher airspeed requires a lower power setting and a lower airspeed requires a higher power setting to hold altitude. It does not imply that a decrease ... power produces lower airspeed. The region of reversed command is encountered in the low speed phases of flight. Flight speeds below the speed for maximum endurance (lowest point on the power curve) require higher power settings with a decrease…
