  • 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…

  • Chapter 10. Helicopter Operations › Section 1. Helicopter IFR Operations › 10-1-1. Helicopter Flight Control Systems

    Chapter 10. Helicopter Operations Section 1. Helicopter IFR Operations 10-1-1. Helicopter Flight Control Systems a. The certification requirements for helicopters to operate under Instrument Flight Rules (IFR) are contained in 14 CFR part 27, Airworthiness Standards: Normal Category ... Rotorcraft, and 14 CFR part 29, Airworthiness Standards: Transport Category Rotorcraft. To meet these requirements, helicopter manufacturers usually utilize a set of stabilization and/or Automatic Flight Control Systems (AFCSs). b. Typically, these systems fall into the following categories: 1. Aerodynamic…

    discretion. 2. Recommended Practice. Helideck size, structural weight capability, and type of main rotor on the parked and operating helicopter will aid in determining accessibility by a second helicopter. Pilots should determine that multi-helicopter deck operations are permitted ... helideck owner/operator. 3. Recommended Criteria (a) Minimum one-third rotor diameter clearance (1/3 RD). The landing helicopter maintains a minimum 1/3 RD clearance between the tips of its turning rotor and the closest part of a parked and secured helicopter…

  • 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 ... 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 than…

  • Chapter 7: Helicopter Instrument Procedures › Helicopter Flight Manual Limitations

    tailwind, the descent rate increases to 1,056 fpm. “Copter” Point-in-space (PinS) approach procedures are restricted to helicopters with a maximum VMINI of 70 KIAS and an IFR approach angle that enables them to meet the final approach ... angle/descent gradient. Pilots of helicopters with Helicopters are certificated for IFR operations with either one or two pilots. Certain equipment is required to be installed and functional for two-pilot operations and additional equipment is required for single-pilot operation…

  • Chapter 5: Physics for Aviation › Helicopter Axes of Flight

    Helicopter Axes of Flight Helicopters, like airplanes, have a vertical, lateral, and longitudinal axis that passes through the helicopter’s center of gravity. Helicopters yaw around the vertical axis, pitch around the lateral axis, and rotate around the longitudinal axis ... Figure 5-90 shows the three axes of a helicopter and how they relate to the helicopter’s movement. All three axes will intersect at the helicopter’s center of gravity, and the helicopter pivots around this point. Notice…
