  cyclic pressure to maintain altitude. 2. Initially applying aft cyclic stick too rapidly, causing the helicopter to balloon (climb). 3. Failing to effectively control the rate of deceleration to accomplish the desired results. 4. Allowing the helicopter to stop forward ... vortex ring state (20–100 percent of available power applied, airspeed of less than 10 knots, and a rate of descent greater than 300 feet per minute (fpm)). For additional information on vortex ring state (formerly referenced as settling-with…

  each 1,000 feet of altitude. Proper accounting of density altitude is necessary to accurately predict landing distance. The effect of proper landing speed is important when runway lengths and landing distances are critical. The landing speeds specified ... stall, be difficult to control, or develop high rates of descent. On the other hand, an excessive speed at landing may improve the controllability slightly (especially in crosswinds) but causes an undesirable increase in landing distance. A ten percent excess…

  done immediately in case of an engine failure), lift and drag are reduced, and the helicopter begins an immediate descent, thus producing an upward flow of air through the rotor disk. This upward flow of air through the rotor disk ... provides sufficient thrust to maintain rotor rpm throughout the descent. Since the tail rotor is driven by the main rotor transmission during autorotation, heading control is maintained with the antitorque pedals as in normal flight. Several factors affect the rate…

  aircraft leaving ground effect after takeoff encounters just the reverse of an aircraft entering ground effect during landing. The aircraft leaving ground effect will: • Require an increase in AOA to maintain the same CL • Experience an increase in induced drag ... nose-up change in moment • Experience a reduction in static source pressure and increase in indicated airspeed Ground effect must be considered during takeoffs and landings. For example, if a pilot fails to understand the relationship between the aircraft…

  line that is tangent to the sea level power curve is also tangent to the altitude power curve. The effect of altitude on specific range can also be appreciated from the previous relationships. If a change in altitude causes identical ... this is true to the extent that specific fuel consumption and propeller efficiency are the principal factors that could cause a variation of specific range with altitude. If compressibility effects are negligible, any variation of specific range with altitude…

  This causes a pressure differential that is indicated on the instrument needle as a climb or descent. When the pressure differential stabilizes at a definite ratio, the needle indicates the rate of altitude change. Figure 8-5.
