  • Chapter 9: Basic Flight Maneuvers › Normal Climb › Technique

    Normal Climb The entry into a climb from a hover has already been described in the Normal Takeoff from a Hover subsection; therefore, this discussion is limited to a climb entry from cruising flight. Technique To enter a climb ... cyclic to direct all of the increased power into lift and maintain the airspeed. Remember, a helicopter can climb with the nose down and descend with the nose up. Helicopter attitude changes mainly reflect acceleration or deceleration, not climb…

  • Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Takeoff Performance

    Figure 11-19 illustrates the general effect of wind by the percent change in takeoff or landing distance as a function of the ratio of wind velocity to takeoff or landing speed. The effect of proper takeoff speed is especially ... important when runway lengths and takeoff distances are critical. The takeoff speeds specified in the AFM/POH are generally the minimum safe speeds at which the aircraft can become airborne. Any attempt to take off below the recommended speed means that…

  • Chapter 7: Helicopter Performance › Sample Hover Problem 3 › Climb Performance

    then move left to 5-foot skid height. Drop down to read 66 percent torque required to hover. Climb Performance Figure 7-6. Torque required for cruise or level flight. Most of the factors affecting hover and takeoff performance also ... affect climb performance. In addition, turbulent air, pilot techniques, and overall condition of the helicopter can cause climb performance to vary. A helicopter flown at the best rate-of-climb speed (VY) obtains the greatest gain in altitude over…

  • Chapter 11: Aircraft Performance › Performance › Climb Performance

    Positive climb performance occurs when an aircraft gains PE by increasing altitude. Two basic factors, or a combination of the two factors, contribute to positive climb performance in most aircraft: 1. The aircraft climbs (gains PE) using excess power above ... that required to maintain level flight, or 2. The aircraft climbs by converting airspeed (KE) to altitude (PE). As an example of factor 1 above, an aircraft with an engine capable of producing 200 horsepower (at a given altitude…

  • Chapter 9: Basic Flight Maneuvers › Normal Takeoff from a Hover › Technique

    increase in power requires an increase in the proper antitorque pedal to maintain heading. Maintain a straight takeoff path throughout the takeoff. While accelerating through effective translational lift (position 3), the helicopter begins to climb, and the nose tends ... rise due to increased lift. At this point, adjust the collective to obtain normal climb power and apply enough forward cyclic to overcome the tendency of the nose to rise. At position 4, hold an attitude that allows a smooth…

  • Chapter 6: Takeoffs and Departure Climbs › Soft/Rough-Field Takeoff and Climb › Initial Climb

    Initial Climb After a positive rate of climb is established, and the airplane has accelerated to VY, the pilot should retract the landing gear and flaps, if equipped. If departing from an airstrip with wet snow or slush ... takeoff surface, the gear should not be retracted immediately so that any wet snow or slush can be air-dried. In the event an obstacle needs to be cleared after a soft-field takeoff, the pilot should perform the climb…
