  • Chapter 10: Performance Maneuvers › Lazy Eight

    Lazy Eight The lazy eight is a maneuver that is designed to develop the proper coordination of the flight controls across a wide range of airspeeds and attitudes. It is the only standard flight training maneuver in which flight control ... pressures are constantly changing. In an attempt to simplify the discussion about this maneuver, the lazy eight can be loosely compared to the ground reference maneuver, S-turns across the road. Recall that S-turns across the road are made…

  • Chapter 9: Techniques of Flight Instruction › Postflight Evaluation › First Solo Flight

    First Solo Flight During the learner’s first solo flight, the instructor needs to be present to assist in answering questions or resolving any issues that arise during the flight. To ensure the solo flight is a positive, confidence-building ... experience for the learner, the flight instructor needs to consider time of day when scheduling the flight. Time of day is a factor in traffic congestion, possible winds, sun angles, and reflection. If possible, the flight instructor needs access…

  • Chapter 3: Basic Flight Maneuvers › Straight-and-Level Flight › Straight Flight

    Straight Flight Maintaining a constant direction or heading is accomplished by visually checking the relationship of the airplane’s wingtips to the natural horizon. Depending on whether the airplane is a high wing or low wing, both wingtips should ... level and equally above or below the natural horizon. Any necessary bank corrections are made with the pilot’s coordinated use of ailerons and rudder. [Figure 3-7] The pilot should understand that anytime the wings are banked, the airplane…

  • Chapter 9: Techniques of Flight Instruction › Sterile Flight Deck Rule

    Sterile Flight Deck Rule Commonly known as the “sterile flight deck rule,” Title 14 of the Code of Federal Regulations (14 CFR) part 121, section 121.542 requires airline flight crewmembers to refrain from nonessential activities during critical phases of flight ... defined in the regulation, critical phases of flight are all ground operations involving taxi, takeoff, and landing, and all other flight operations below 10,000 feet except cruise flight. Nonessential activities include such activities as eating, reading a newspaper…

    throughout the maneuver. 2. Failure to establish a constant, level altitude prior to entering the maneuver. 3. Failure to maintain altitude during the maneuver. 4. Failure to properly assess wind direction. 5. Failure to properly execute constant-radius turns ... Failure to manipulate the flight controls in a smooth and continuous manner when transitioning into turns. 7. Failure to establish the appropriate wind correction angle. 8. Failure to apply coordinated aileron and rudder pressure, resulting in slips or skids. Elementary…

  • Chapter 1: Introduction to Flight Training › Safety Considerations › Use of Checklists

    Descent ⦁ Before landing ⦁ After landing ⦁ Engine shutdown and securing Figure 1-17. A sample checklist used by pilots. During flight training, there should be a clear understanding between the learner and flight instructor of who has control of the aircraft ... Prior to any flight, a briefing should be conducted that includes the procedures for the exchange of flight controls. The following three-step process for the exchange of flight controls is highly recommended. When a flight instructor wishes the learner…
