  • Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Flight Maneuvers

    Spins Load Factors and Flight Maneuvers Critical load factors apply to all flight maneuvers except unaccelerated straight flight where a load factor of 1 G is always present. Certain maneuvers considered in this section are known to involve relatively high ... load factors. Full application of pitch, roll, or yaw controls should be confined to speeds below the maneuvering speed. Avoid rapid and large alternating control inputs, especially in combination with large changes in pitch, roll, or yaw (e.g., large sideslip…

  • Chapter 2: Aerodynamics of Flight › Forward Flight › Airflow in Forward Flight

    blade continues to rotate, velocity of the airflow then increases to rotational velocity over the tail. It continues to increase until the blade is back at the 3 o’clock position. The advancing blade in Figure 2-35, position ... moves in the same direction as the helicopter. The velocity of the air meeting this blade equals rotational velocity of the blade plus wind velocity resulting from forward airspeed. The retreating blade (position C) moves in a flow…

  • Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Stalling Speeds

    Load Factors and Stalling Speeds Any aircraft, within the limits of its structure, may be stalled at any airspeed. When a sufficiently high AOA is imposed, the smooth flow of air over an airfoil breaks up and separates, producing ... effect has revealed that an aircraft’s stalling speed increases in proportion to the square root of the load factor. This means that an aircraft with a normal unaccelerated stalling speed of 50 knots can be stalled at 100 knots…

  • Appendix C: Certificates, Ratings, and Endorsements › Flight Instructor Endorsements › Sport Pilot

    basic requirements. Forms 8710-1, 8610-2, and 8710-11 are versions of the Airman Certificate and/or Rating Application. The instructor should ensure the applicant is prepared for the test and has met all the regulatory requirements, including knowledge, proficiency ... required endorsements, and experience requirements before the application process. The applicant then either completes the 8710 or 8610 paper form by hand or uses the Integrated Airman Certification and Rating Application (IACRA) electronic application system available at iacra.faa.gov/IACRA/Default.aspx. Whenever…

  • Chapter 5: Aerodynamics of Flight › Load Factors › Vg Diagram

    Diagram The flight operating strength of an aircraft is presented on a graph whose vertical scale is based on load factor. [Figure 5-55] The diagram is called a Vg diagram—velocity versus G loads or load factor. Each aircraft ... diagram that is valid at a certain weight and altitude. The lines of maximum lift capability (curved lines) are the first items of importance on the Vg diagram. The aircraft in Figure 5-53 is capable of developing no more…

  • 14 CFR § 61.195 Flight instructor limitations and qualifications.

    Flight instructor limitations and qualifications. (B) Teaching methods, procedures, and techniques applicable to instructing an initial flight instructor applicant. (C) Methods of proper evaluation of an initial flight instructor applicant to detect improper and insufficient transfer of instructional knowledge, training ... performance of the initial flight instructor applicant. (D) Corrective action in the case of unsatisfactory training progress. (ii) The flight training must include at least 10 hours of training that includes the following areas: (A) Scenario-based training to develop…
