  • Chapter 6: Takeoffs and Departure Climbs › Short-Field Takeoff and Maximum Performance Climb

    speed. The pilot should reduce AOA to attain normal airspeed before attempting to fly out of the ground effect areas. Short-Field Takeoff and Maximum Performance Climb When performing takeoffs and climbs from fields where the takeoff area is short ... available takeoff area is restricted by obstructions, the pilot should operate the airplane at the maximum limit of its takeoff performance capabilities. To depart from such an area safely, the pilot needs to exercise positive and precise control of airplane…

  • 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 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 6: Takeoffs and Departure Climbs › Short-Field Takeoff and Maximum Performance Climb › Takeoff Roll

    Takeoff Roll Taking off from a short field requires the takeoff to be started from the very beginning of the takeoff area. At this point, the airplane is aligned with the intended takeoff path. If the airplane manufacturer recommends ... flaps, they are extended the proper amount before beginning the takeoff roll. This allows the pilot to devote full attention to the proper technique and the airplane’s performance throughout the takeoff. The pilot should apply takeoff power smoothly…

  • 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…

  • Chapter 11: Aircraft Performance › Performance › Rate of Climb (ROC)

    Rate of Climb (ROC) ROC is a comparison of altitude gained relative to the time needed to reach that altitude. ROC is simply the vertical component of the aircraft’s flight path velocity vector. For maximum ROC performance, a pilot ... flies the aircraft at VY so as to achieve a maximum gain in altitude over a given period of time. Maximum ROC expedites a climb to an assigned altitude. This gains the greatest vertical distance over a period of time…
