- Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Antitorque System Failure
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 of the 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 of the tail rotor…
- Chapter 11: Helicopter Emergencies and Hazards › Recovery Technique (Uncontrolled Right Yaw) › Main Drive Shaft or Clutch Failure
Main Drive Shaft or Clutch Failure The main drive shaft, located between the engine and the main rotor transmission, provides engine power to the main rotor transmission. In some helicopters, particularly those with piston engines, a drive belt is used ... instead of a drive shaft. A failure of the drive shaft clutch or belt has the same effect as an engine failure because power is no longer provided to the main rotor and an autorotation must be initiated. There…

Common Errors 1. Failure to trim the helicopter properly, tending to hold antitorque pedal pressure and opposite cyclic. This is commonly called cross-controlling. 2. Failure to maintain desired airspeed. 3. Failure to hold proper control position to maintain desired ... ground track. 4. Failure to allow helicopter to stabilize at new airspeed. Turns A turn is a maneuver used to change the heading of the helicopter. The aerodynamics of a turn were previously discussed in Chapter 2, Aerodynamics of Flight…
- Chapter 9: Basic Flight Maneuvers › The Four Fundamentals › Guidelines
Guidelines Good practices to follow during maneuvering flight include: 1. Move the cyclic only as fast as trim, torque, and rotor speed can be maintained. When entering a maneuver and the trim, rotor, or torque reacts quicker than anticipated, pilot ... limitations have been exceeded. If continued, an aircraft limitation will be exceeded. Perform the maneuver with less intensity until all aspects of the machine can be controlled. The pilot must be aware of the sensitivity of the flight controls…
- Chapter 9: Basic Flight Maneuvers › Common Errors › S-Turns
Poor planning, orientation, and/or division of attention. 3. Uncoordinated flight control application. 4. Improper correction for wind drift. 5. Failure to maintain selected altitude and airspeed. 6. Selection of a ground reference with no suitable emergency landing area within gliding ... flying a course parallel to the intended area (e.g., traffic pattern or square field). S-Turns Another training maneuver to use is the S-turn, which helps correct for wind drift in turns. This maneuver requires turns to the left…
