  • Chapter 13: Transition to Multiengine Airplanes › Short-Field Takeoff and Climb

    rotation and lift-off, the airplane should be allowed to accelerate to VX, making the initial climb over obstacles at VX and transitioning to VY as obstacles are cleared. [Figure 13-8] Figure 13-8. Short-field takeoff and climb ... recommended for short-field takeoffs, many light-twins have a strong tendency to become airborne prior to VMC plus 5 knots. Attempting to prevent premature lift-off with forward elevator pressure results in wheel barrowing. To prevent this, allow…

  • Chapter 11: Aircraft Performance › Performance Charts › Sample Problem 3

    find the corresponding takeoff speeds at lift-off and over the 50 foot obstacle, refer to the table on the top of the chart. In this case, the lift-off speed at 2,600 pounds would be 63 knots ... over the 50 foot obstacle would be 68 knots. Figure 11-21. Interpolating charts. Figure 11-22. Density altitude chart. Sample Problem 3 Refer to Figure 11-24. This chart is an example of a takeoff distance table for short…

  • Chapter 11: Aircraft Performance › Performance › Climb Performance

    increases power to perform the climb. As an example of factor 2, an aircraft is flying level at 120 knots. The pilot leaves the engine power setting constant but applies other control inputs to perform a climb. The climb, sometimes ... called a zoom climb, converts the airspeed (KE) to altitude (PE); the airspeed decreases to something less than 120 knots as the altitude increases. There are two primary reasons to evaluate climb performance. First, aircraft must climb over obstacles…

  • 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 ... 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-out at VX until the obstacle…

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

    allow the airplane to lift off in ground effect and then reduce pitch attitude to level until the airplane accelerates to VX with the wheels just clear of the runway surface. This method is preferable to forcing the airplane ... ground unnecessarily puts excessive pressure on the nose-wheel and may result in “wheel barrowing.” It also hinders both acceleration and overall airplane performance. Initial Climb On short-field takeoffs, the landing gear and flaps should remain in takeoff position…

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

    until reaching the appropriate VX attitude to ensure a smooth and firm lift-off, or rotation. Since the airplane accelerates more rapidly after lift-off, the pilot should apply additional back-elevator pressure to hold a constant airspeed. After becoming ... airborne, the pilot will maintain a wings-level climb at VX until all obstacles have been cleared, or if no obstacles are present, until reaching an altitude of at least 50 feet above the takeoff surface. Thereafter, the pilot…
