  • Chapter 2: Aeronautical Decision-Making › TEAM Checklist: Choose and Implement Risk Controls › The DECIDE Model

    First, adjust the power to the maximum controllable level on both engines. Because the left engine is the only engine delivering thrust, the yaw increases to the right, which necessitates application of additional left rudder application. Figure ... worldwide. Its application is illustrated in column A while automatic/naturalistic decision-making is shown in column B. The failed engine is the side that requires no rudder pressure, in this case the right engine. Second, having identified the failed right…

  • Chapter 1: Introduction to the Helicopter › Controlling Flight › Throttle

    Throttle Helicopter rotors are designed to operate at a specific rpm. Figure 1-11. The throttle control mounted at the end of the collective control. The throttle controls the power produced by the engine, which is connected to the rotor ... transmission. The purpose of the throttle is to maintain enough engine power to keep the rotor rpm within allowable limits to produce enough lift for flight. In single-engine helicopters, if so equipped, the throttle control is typically a twist…

  • Chapter 1: Introduction to the Helicopter › Turbine Age

    pilot must work in three dimensions and use both arms and both legs constantly to keep the helicopter in a desired state. Coordination, timing and control touch are all used simultaneously when flying a helicopter. Although helicopters were developed ... built during the first half-century of flight, some even reaching limited production; it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Even though most previous designs used more…

  • 14 CFR § 91.611 Authorization for ferry flight with one engine inoperative.

    Authorization for ferry flight with one engine inoperative. (i) Limiting the operating weight on any ferry flight to the minimum necessary for the flight plus the necessary reserve fuel load; (ii) A limitation that takeoffs must be made from ... runways unless, based on a showing of actual operating takeoff techniques on wet runways with one engine inoperative, takeoffs with full controllability from wet runways have been approved for the specific model aircraft and included in the Airplane Flight Manual…

  • Chapter 8: Helicopter Attitude Instrument Flying › Instrument Flight › Aircraft Control

    Aircraft Control Controlling a helicopter is the result of accurately interpreting the flight instruments and translating these readings into correct control responses. Aircraft control involves adjustment to pitch, bank, power, and trim in order to achieve a desired flight path ... Pitch attitude control is controlling the movement of the helicopter about its lateral axis. After interpreting the helicopter’s pitch attitude by reference to the pitch instruments (attitude indicator, altimeter, airspeed indicator, and vertical speed indicator (VSI)), cyclic control adjustments…

  • Chapter 10. Helicopter Operations › Section 2. Special Operations › 10-2-4. Emergency Medical Service (EMS) Multiple Helicopter Operations

    Emergency Medical Service (EMS) Multiple Helicopter Operations a. Background. EMS helicopter operators often overlap other EMS operator areas. Standardized procedures can enhance the safety of operating multiple helicopters to landing zones (LZs) and to hospital heliports. Communication ... successful operations and in maintaining organization between helicopters, ground units and communication centers. EMS helicopter operators which operate in the same areas should establish joint operating procedures and provide them to related agencies. b. Recommended Procedures. 1. Landing Zone Operations…
