- Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Loss of Tail Rotor Effectiveness (LTE)
should also be applied to understanding aerodynamic conditions. If flight envelopes are exceeded, the end results can be catastrophic. LTE is an aerodynamic condition and is the result of a control margin deficiency in the tail rotor. It can affect ... single-rotor helicopters that utilize a tail rotor. The design of main and tail rotor blades and the tail boom assembly can affect the characteristics and susceptibility of LTE but will not nullify the phenomenon entirely. Translational lift is obtained…
- 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 3: Helicopter Flight Controls › Antitorque Pedals
This results in maximum downward deflection of the rotor blade in front of the helicopter and maximum upward deflection behind it, causing the rotor disk to tilt forward. Figure 3-4. The cyclic pitch control may be mounted vertically between ... from a single cyclic located in the center of the helicopter. The cyclic can pivot in all directions. Antitorque Pedals The antitorque pedals, located on the cabin floor by the pilot’s feet, control the pitch and therefore the thrust…
- Chapter 7: Helicopter Performance › Factors Affecting Performance › Winds
velocity also affect hovering, takeoff, and climb performance. Translational lift occurs any time there is relative airflow over the rotor disk. This occurs whether the relative airflow is caused by helicopter movement or by the wind. Assuming a headwind ... they contribute to the greatest increase in performance. Strong crosswinds and tailwinds may require the use of more tail rotor thrust to maintain directional control. This increased tail rotor thrust absorbs power from the engine, which means there is less…
- 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…
- Appendix D. REMOTE PILOT CERTIFICATION AND APPLICANT IDENTITY VERIFICATION › D.4 CFI Registration Process for Accepting an Application for a Remote Pilot Certificate
D.1.2 Additional information on the eligibility requirements for remote pilots can be found at Note: If an applicant has a known medical issue that would require a limitation on the Remote Pilot Certificate, refer that applicant to the responsible Flight ... Standards office to ensure the application is processed with the correct limitations. D.2 Acceptance of a Remote Pilot Application. Certifying officials may accept an individual’s application for an FAA Remote Pilot Certificate by utilizing the FAA’s IACRA…
