- 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 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 5: Aerodynamics of Flight › Ground Effect
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…
- Chapter 6: Takeoffs and Departure Climbs › Short-Field Takeoff and Maximum Performance Climb
runway is long enough or if no obstacles exist, ground effect can be used to the pilot’s advantage by using the reduced drag to improve initial acceleration. When taking off from an unsatisfactory surface, the pilot should apply ... much weight to the wings as possible during the ground run and lift-off, using ground effect as an aid, prior to attaining true flying speed. The pilot should reduce AOA to attain normal airspeed before attempting…
- Chapter 7: Helicopter Performance › Sample Hover Problem 3 › Climb Performance
Sample Hover Problem 3 Using Figure 7-6, determine what torque is required to hover. Use the following conditions: First, enter the chart at 9,500 feet pressure altitude, then move right to outside air temperature, 0 °C. From 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…
