- Chapter 7, Section I: Airplane Basic Flight Maneuvers › Straight-and-Level Flight › Turn-and-Slip Indicator (Needle and Ball)
forces of gravity, drag, and inertia to determine airplane performance. Power control must be related to its effect on altitude and airspeed, since any change in power setting results in a change in the airspeed or the altitude ... airplane. At any given airspeed, the power setting determines whether the airplane is in level flight, in a climb, or in a descent. If the power is increased in straight-and-level flight and the airspeed held constant, the airplane…

with counter-rotating rotors. To counteract the yawing tendency of the helicopter, apply pedal trim during power changes. To maintain a constant altitude and airspeed in level flight, coordinate pitch attitude and power control. The relationship between altitude and airspeed ... determines the need for a change in power and/or pitch attitude. If the altitude is constant and the airspeed is high or low, change the power to obtain the desired airspeed. During the change in power, make an accurate interpretation…
- Chapter 7, Section II: Airplane Basic Flight Maneuvers › Straight-and-Level Flight › Power Settings
Power Settings Power control and airspeed changes are much easier when approximate power settings necessary to maintain various airspeeds in straight-and-level flight are known in advance. However, to change airspeed by any appreciable amount, the common procedure ... underpower or overpower on initial power changes to accelerate the rate of airspeed change. (For small speed changes, or in airplanes that decelerate or accelerate rapidly, overpowering or underpowering is not necessary.) Consider the example of an airplane that requires…

Figure 7-10. Pitch correction, less than 100 feet—one-half bar low to correct altitude error. When using the VSI as a rate instrument and combining it with the altimeter and attitude indicator to maintain level flight, a pilot ... should know that the amount the altimeter needle moves from the desired altitude governs the rate that should be used to return to that altitude. A rule of thumb is to make an attitude change that results in a vertical…
