- 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…

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 9: Basic Flight Maneuvers › Normal Takeoff from a Hover › Technique
Normal Takeoff from a Hover A normal takeoff from a hover is an orderly transition to forward flight and is executed to increase altitude safely and expeditiously. Before initiating a takeoff, the pilot should ensure that the proper checklist ... been completed and the helicopter systems are within normal limits. During the takeoff, fly a profile that avoids the cross-hatched or shaded areas of the height/velocity diagram. Technique Refer to Figure 9-12 (position 1). Bring the helicopter…
- Chapter 6: Takeoffs and Departure Climbs › Crosswind Takeoff › Takeoff Roll
Crosswind Takeoff While it is usually preferable to take off directly into the wind whenever possible or practical, there are many instances when circumstances or judgment indicate otherwise. Therefore, the pilot must be familiar with the principles and techniques involved ... crosswind takeoffs, as well as those for normal takeoffs. A crosswind affects the airplane during takeoff much as it does during taxiing. With this in mind, the pilot should be aware that the technique used for crosswind correction during takeoffs…
