- Chapter 4: Helicopter Components, Sections, and Systems › Electrical Systems
Electrical Systems The electrical systems, in most helicopters, reflect the increased use of sophisticated avionics and other electrical accessories. [Figure 4-24] More and more operations in today’s flight environment are dependent on the aircraft’s electrical system; however ... helicopters can be safely flown without any electrical power in the event of an electrical malfunction or emergency. Helicopters have either a 14- or 28-volt, direct-current electrical system. On small, piston powered helicopters, electrical energy is supplied…

comprised of glass fiber reinforced material. The hub is a single piece of forged rigid titanium. The rigid rotor system is very responsive and is usually not susceptible to mast bumping like the semirigid systems because the rotor hubs ... fuselage to move together as one entity and eliminates much of the oscillation usually present in the other rotor systems. Other advantages of the rigid rotor include a reduction in the weight and drag of the rotor…
- Chapter 4: Helicopter Components, Sections, and Systems › Hydraulics
Hydraulics Most helicopters, other than smaller piston-powered helicopters, incorporate the use of hydraulic actuators to overcome high control forces. [Figure 4-25] A typical hydraulic system consists of actuators, also called servos, on each flight control, a pump which ... usually driven by the main rotor transmission and a reservoir to store the hydraulic fluid. Some helicopters have accumulators located on the pressure side of the hydraulic system. This allows for a continuous fluid pressure into the system. A switch…
- Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Antitorque System Failure
System Malfunctions By following the manufacturer’s recommendations regarding operating limits and procedures and periodic maintenance and inspections, many system and equipment failures can be eliminated. Certain malfunctions or failures can be traced to some error on the part ... pilot; therefore, appropriate flying techniques and use of threat and error management may help to prevent an emergency Antitorque System Failure Antitorque failure usually falls into one of two categories. One is failure of the power drive portion…
- Chapter 7: Aircraft Systems › Heating System › Exhaust Heating Systems
Exhaust Heating Systems Exhaust heating systems are the simplest type of aircraft heating system and are used on most light aircraft. Exhaust heating systems are used to route exhaust gases away from the engine and fuselage while reducing engine noise ... exhaust systems also serve as a heat source for the cabin and carburetor. The risks of operating an aircraft with a defective exhaust heating system include carbon monoxide poisoning, a decrease in engine performance, and an increased potential for fire…

Indications exist for all tanks on a transport category aircraft. Often, these use a capacitance type fuel quantity indication system and a fuel totalizer as is discussed later in this chapter. The location of fuel instrumentation varies depending ... type of flight deck displays utilized on the aircraft. Helicopter Fuel Systems Helicopter fuel systems vary. They can be simple or complex depending on the aircraft. Always consult the manufacturer’s manuals for fuel system description, operation, and maintenance instructions…
