  • Chapter 4: Energy Management: Mastering Altitude and Airspeed Control › Viewing the Airplane as an Energy System › A Frame of Reference for Managing Energy State

    example, if the pilot decides to put all the surplus energy into altitude, the airplane can climb at a constant airspeed. [Figure 4-1A] If the pilot opts to place all the surplus energy into airspeed, the airplane ... accelerate while maintaining altitude. [Figure 4-1B] When drag exceeds thrust, (T – D < 0), the airplane's total mechanical energy decreases. The pilot has two sources of stored energy to tap into. For example, the pilot may choose…

  • Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Slow Flight

    pilot training and testing purposes, slow flight includes two main elements: ⦁ Slowing to, maneuvering at, and recovering from an airspeed at which the airplane is still capable of maintaining controlled flight without activating the stall warning—5 to 10 knots ... above the 1G stall speed is a good target. ⦁ Performing slow flight in configurations appropriate to takeoffs, climbs, descents, approaches to landing, and go-arounds. Slow flight should be introduced with the target airspeed sufficiently above the stall to permit…

  • Chapter 8: Flight Instruments › Instrument Check › Airspeed Indicator (ASI)

    side of the diaphragm, which is attached to an indicating system. The system drives the mechanical linkage and the airspeed needle. Just as in altitudes, there are multiple types of airspeeds. Pilots need to be very familiar with each type ... Indicated airspeed (IAS)—the direct instrument reading obtained from the ASI, uncorrected for variations in atmospheric density, installation error, or instrument error. Manufacturers use this airspeed as the basis for determining aircraft performance. Takeoff, landing, and stall speeds listed…

  • Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Slow Flight › Performing the Slow Flight Maneuver

    pilot should clear the area and gradually reduce thrust from cruise power and adjust the pitch to allow the airspeed to decrease while maintaining altitude. As the speed of the airplane decreases, there is a change in the sound ... airflow. As the speed approaches the target slow flight speed, which is an airspeed just above the stall warning in the desired configuration (i.e., approximately 5–10 knots above the stall speed for that flight condition), additional power will…

  • Chapter 11: Aircraft Performance › Performance › Climb Performance

    Positive climb performance occurs when an aircraft gains PE by increasing altitude. Two basic factors, or a combination of the two factors, contribute to positive climb performance in most aircraft: 1. The aircraft climbs (gains PE) using excess power above ... that required to maintain level flight, or 2. The aircraft climbs by converting airspeed (KE) to altitude (PE). As an example of factor 1 above, an aircraft with an engine capable of producing 200 horsepower (at a given altitude…

  • Chapter 18: Emergency Procedures › Inadvertent VFR Flight Into IMC › Attitude Control

    Attitude Control An airplane is, by design, an inherently stable platform and, except in turbulent air, maintains approximately straight-and-level flight if properly trimmed and left alone. It is designed to maintain a state of equilibrium in pitch, roll ... slightly less in the pitch axis, and even lesser still in the roll axis. The key to emergency airplane attitude control, therefore, is to: ⦁ Trim the airplane with the elevator trim so that it maintains hands-off level flight…
