  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…

  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…

  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…

  could be accepted. There is a light rain and the winds are out of the east at ten knots. The pilot accepts because he or she is approaching the extended centerline of runway 27. The turn is tight ... pilot must descend (dive) to get to runway 27. After becoming aligned with the runway and at 50 feet AGL, the pilot is already 1,000 feet down the 3,500 feet runway. The airspeed is still high by about…

  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…

  LANDING › GLASSY WATER LANDING

  Another technique is to make the final approach over land, crossing the shoreline at the lowest possible safe altitude so that a reliable height reference is maintained to within a few feet of the water surface. When adequate visual references ... perform glassy water landings with power. Perform a normal approach, but prepare as though intending to land at an altitude well above the surface. For example, in a situation where a current altimeter setting is not available and there…
