  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…

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

  Level Off The level off from a constant airspeed climb must be started before reaching the desired altitude. Although the amount of lead varies with the type of helicopter being flown and pilot technique, the most important factor is vertical ... vertical velocity as the lead point. For example, if the rate of climb is 500 fpm, initiate the level off approximately 50 feet before the desired altitude. When the proper lead altitude is reached, the altimeter becomes primary for pitch…

  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…

  Chapter 7, Section II: Airplane Basic Flight Maneuvers › Straight Climbs and Descents › Leveling Off

  Leveling Off When leveling off from a descent with the intention of returning to cruise airspeed, first start by increasing the power to cruise prior to increasing the pitch back toward the level flight attitude. A technique used to determine ... soon to start the level off is to lead the level off by an altitude corresponding to 10 percent of the rate of descent. For example, if the aircraft is descending at 1,000 fpm, start the level…
