  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…

  Chapter 7, Section II: Airplane Basic Flight Maneuvers › Straight-and-Level Flight › Airspeed Changes in Straight-and-Level Flight

  Accordingly, knowledge of the power settings and trim changes associated with different combinations of airspeed, gear, and flap configurations reduces instrument cross-check and interpretation problems. [Figure 7-60] For example, assume that in straight-and-level flight instruments indicate ... knots with power at 23 "Hg manifold pressure/2,300 revolutions per minute (rpm), gear and flaps up. After reduction in airspeed, with gear and flaps fully extended, straight-and-level flight at the same altitude requires 25 "Hg manifold pressure/2…

  airspeed is changing, adjust the pitch attitude to maintain a constant altitude. A constant heading should be maintained throughout the change. As the desired airspeed is approached, adjust power to the new cruising power setting and further adjust pitch attitude ... maintain altitude. The instrument indications for straight-and-level flight at normal cruise and during the transition from normal cruise to slow cruise are illustrated in Figures 8-9 and 8-10. After the airspeed stabilizes at slow cruise…

  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…

  Chapter 8: Helicopter Attitude Instrument Flying › Straight Descents (Constant Airspeed and Constant Rate) › Level Off

  Level Off The level off from a constant airspeed descent may be made at descending airspeed or at cruise airspeed, if this is higher than descending airspeed. As in a climb level off, the amount of lead depends ... rate of descent and control technique. For a level off at descending airspeed, the lead should be approximately 10 percent of the vertical speed. At the lead altitude, simultaneously increase power to the setting necessary to maintain descending airspeed…

  Chapter 7, Section I: 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. Figure 7-20. Airspeed low and altitude high—lower pitch. (For small speed changes, or in airplanes that decelerate or accelerate rapidly, overpowering or underpowering…
