  • Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Loss of Tail Rotor Effectiveness (LTE)

    The key is not to put the helicopter in a compromising condition…

  • Chapter 11: Helicopter Emergencies and Hazards › Low Rotor RPM and Rotor Stall

    Other causes of a power-on low rotor rpm condition include the pilot rolling the throttle the wrong way in helicopters not equipped with a governor or a governor failure in helicopters so equipped. As the rpm decreases, the amount ... horsepower the engine can produce also decreases. Engine horsepower is directly proportional to its rpm, so a 10 percent loss in rpm due to overpitching, or one of the other scenarios above, will result in a 10 percent loss…

  • Chapter 11: Helicopter Emergencies and Hazards › Autorotation

    Following this general procedure of fitting airspeed and rotor rpm to existing conditions, a pilot can achieve approximately the same glide angle in any set of circumstances, and thereby estimate the touchdown point accurately. Figure 11-1. During an autorotation ... upward flow of relative wind permits the main rotor blades to rotate at their normal speed. In effect, the blades are “gliding” in their rotational plane. It is important that pilots experience autorotations from various airspeeds. This provides better understanding…

  • CHAPTER 6. PART 107 SUBPART C, REMOTE PILOT CERTIFICATION › 6.4 Application Process › 6.4.1 Remote Pilot Applicants Without Part 61 Certificates

    Once the applicant completes the online application in IACRA, the applicant signs the application electronically and submits it to the Airman Registry for processing. No FAA representative will be required to sign the application if the applicant was able ... self-certify. Note: When an applicant seeking a Remote Pilot Certificate uses this online option, the application transmits electronically from the applicant to the Airman Registry. The only electronic signature reflected on the IACRA application will be the applicant…
