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 8: Helicopter Attitude Instrument Flying › Straight Descents (Constant Airspeed and Constant Rate) › Entry
Straight Descents (Constant Airspeed and Constant Rate) A descent may be performed at any normal airspeed the helicopter can attain, but the airspeed must be determined prior to entry. The technique is determined by the type of descent, a constant ... airspeed, or a constant rate. Entry If airspeed is higher than descending airspeed, and a constant airspeed descent is desired, reduce power to a descent power setting and maintain a constant altitude using cyclic pitch control. This slows the helicopter…

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…

first neutralizing the controls and allowing the pitch attitude to stabilize, then readjusting the pitch attitude by noting the indications of the other pitch instruments. Occasionally, the VSI may be slightly out of calibration. This could result in the instrument ... indicating a slight climb or descent even when the helicopter is in level flight. If the instrument cannot be calibrated properly, this error must be taken into consideration when using the VSI for pitch control. For example, if a descent…

turning, make a small change of bank attitude to center the turn needle and stop the movement of the heading indicator. In coordinated flight, the heading indicator gives an indirect indication of a helicopter’s bank attitude. When a helicopter ... turns. When the lateral axis of a helicopter is level, it flies straight. Therefore, in coordinated flight when the heading indicator shows a constant heading, the helicopter is level laterally. A deviation from the desired heading indicates a bank…

aircraft may hold at the following altitudes and maximum holding airspeeds: Altitude Mean Sea Level (MSL) Airspeed (KIAS) Up to 6,000 feet 200 14,001 feet and above 265 The following are exceptions to the maximum holding airspeeds ... Holding patterns from 6,001 to 14,000 feet may be restricted to a maximum airspeed of 210 knots indicated airspeed (KIAS). This nonstandard pattern is depicted by an icon. 2.
