  • Chapter 7: Aircraft Systems › Starting System

    starter engages the aircraft flywheel, rotating the engine at a speed that allows the engine to start and maintain operation. Electrical power for starting is usually supplied by an onboard battery, but can also be supplied by external power through ... starter switch draw current from the main bus bar, but the starter will not operate until the starting solenoid is energized by the starter switch being turned to the “start” position. When the starter switch is released from the “start…

  • Chapter 6: Flight Controls › Flight Control Systems › Leading Edge Devices

    slat allows the air below the wing to flow over the wing’s upper surface, delaying airflow separation. Leading edge flaps, like trailing edge flaps, are used to increase both CL-MAX and the camber of the wings. This type ... leading edge device is frequently used in conjunction with trailing edge flaps and can reduce the nose-down pitching movement produced by the latter. As is true with trailing edge flaps, a small increment of leading edge flaps increases lift…

  • Chapter 9: Techniques of Flight Instruction › Positive Exchange of Flight Controls › Procedure

    Procedure During flight training, there should always be a clear understanding between learners and flight instructors about who has control of the aircraft. The preflight briefing should include procedures for the exchange of flight controls. A positive three-step process ... exchange of flight controls between pilots is a proven procedure and one that is strongly recommended. When an instructor is teaching a maneuver to a learner, the instructor normally demonstrates the maneuver first, then has the learner follow along…

  • Chapter 6: Threat and Error Management › Defenses Provided to the Pilot or Crew › Checklists, Standard Operating Procedures, and Best Practices

    Defenses against Threats, Errors, and Undesired Aircraft States When a pilot perceives a flight condition that requires attention, the pilot may know what to do immediately or may need time to process alternatives. The pilot may utilize several different strategies ... flight school may provide defenses to pilots. Examples include checklists, operating limitations, minimum pilot qualifications, standard operating procedures, and insurance requirements. Regardless of the flight mission, some defenses will always be predetermined. Checklists, Standard Operating Procedures, and Best Practices Like…

  • Chapter 11: Aircraft Performance › Performance › Straight-and-Level Flight

    Straight-and-Level Flight All of the principal components of flight performance involve steady-state flight conditions and equilibrium of the aircraft. For the aircraft to remain in steady, level flight, equilibrium must be obtained by a lift equal ... speed, induced drag predominates at low speed. [Figure 11-5] For example, if an aircraft in a steady flight condition at 100 knots is then accelerated to 200 knots, the parasite drag becomes four times as great, but the power…

  • Chapter 1: Safety, Ground Operations, & Servicing › Ground Movement of Aircraft › Starting a Turbofan Engine

    very serious accidents have occurred involving personnel in the vicinity of turbine engine air inlets. Use extreme caution when starting turbine aircraft. Check the aircraft fuel sumps for water or ice. Inspect the engine air inlet for general condition ... blades by hand. All engine controls must be operational. Check engine instruments and warning lights for proper operation. Starting a Turbofan Engine The following procedures are typical of those used to start many turbine engines. There are, however, wide variations…
