Chapter 8: Helicopter Attitude Instrument Flying › Turn Indicator › Power Control During Straight-and-Level Flight
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…

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…

result, acceptance of its indication should be considered with other instruments that indicate turn information. These include the already mentioned attitude and heading indicators, as well as the turn-and-slip indicator and turn coordinator. Turn Coordinator/Turn-and-Slip Indicator Both ... turn coordinator provides both bank rate and then turn rate once stabilized. The turn-and-slip indicator provides only turn rate. Figure 6-12.

While examining the top of the heading indicator, notice two white lines on the exterior of the compass rose. [Figure 6-38] These two tick marks located on both sides of the top of the heading indicator show half-standard ... standard rate turns. In Figure 6-39, when the aircraft begins its turn to the left, the magenta trend indicator elongates proportionally with the rate of turn. To initiate a half-standard rate turn, position the indicator on the first…
