  • Chapter 11: Helicopter Emergencies and Hazards › Recovery Technique (Uncontrolled Right Yaw) › Governor or Fuel Control Failure

    before responding to any type of mechanical failure, pilots should confirm that rotor rpm is not responding to flight control inputs. If the rotor rpm can be maintained in the green operating range, the failure is in the instrument…

  • Chapter 10: Teaching Practical Risk Management during Flight Instruction › Notes on Instructional Risk Management in the Flight Deck › Managing Risk while Teaching Takeoffs

    learner. The instructor should conduct the majority of their teaching (e.g. airspeeds, pitch attitudes, visual references, flight control inputs, engine parameters) prior to contacting tower or announcing their intentions on the CTAF at a non-towered airport. This will avoid…

  • Chapter 11: Helicopter Emergencies and Hazards › Autorotation

    plane. It is important that pilots experience autorotations from various airspeeds. This provides better understanding of the necessary flight control inputs to achieve the desired airspeed, rotor rpm and autorotation performance, such as the maximum glide or minimum descent airspeed…

  • Chapter 2: Aerodynamics of Flight › Airflow and Reactions in the Rotor Disk › Angle of Attack

    change the rotor blade AOA. The pilot has little direct control over AOA except indirectly through the flight control input. Collective and cyclic feathering help to make these changes. Feathering is the rotation of the blade about its longitudinal axis…

  • Glossary › Chart Supplement U.S. (formerly Airport/Facility

    required flight deck panels. Controllability. A measure of the response of an aircraft relative to the pilot’s flight control inputs. Controllable-pitch propeller (CPP). A type of propeller with blades that can be rotated around their long axis ... reversing without the need of changing the direction of shaft revolutions. Controlled airspace. An airspace of defined dimensions within which ATC service is provided to IFR and VFR flights in accordance with the airspace classification. It includes Class A, Class…

  • Chapter 2: Aeronautical Decision-Making › Automation › Results of the Study

    flown EFIS for several years were required to fly various maneuvers manually, the aircraft parameters and flight control inputs clearly showed some erosion of flying skills. During normal maneuvers, such as turns to headings without a flight director, the EFIS…
