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…

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 10: Advanced Flight Maneuvers › Maximum Performance Takeoff
Positioning the helicopter at the most downwind portion of the confined area gives the pilot the most distance to clear obstacles. Wind analysis also helps determine the route of takeoff. The prevailing wind can be altered by obstructions ... departure path and can significantly affect aircraft performance. There are several ways to check the wind direction before taking off. One technique is to watch the tops of the trees; another is to look for any smoke in the area…
