- Chapter 6: Takeoffs and Departure Climbs › Normal Takeoff › Lift-Off
Lift-Off Since a good takeoff depends on the proper takeoff attitude, it is important to know how this attitude appears and how it is attained. The ideal takeoff attitude requires only minimum pitch adjustments shortly after the airplane lifts ... attain the speed for the best rate of climb (VY). [Figure 6-3] The pitch attitude necessary for the airplane to accelerate to VY speed should be demonstrated by the instructor and memorized by the student. Flight instructors should…

Establishing a Climb A straight climb is entered by gently increasing back pressure on the elevator flight control to the pitch attitude referencing the airplane’s nose to the natural horizon while simultaneously increasing engine power to the climb power ... setting. The wingtips should be referenced in maintaining the climb attitude while cross-checking the flight instruments to verify performance. In many airplanes, as power is increased, an increase in slipstream over the horizontal stabilizer causes the airplane’s pitch…

airspeed indicator when making these pitch changes, but should continue to scan outside to adjust the airplane’s attitude in relation to the horizon. In accordance with the principles of attitude flying, the pilot should first make the necessary pitch ... change with reference to the natural horizon, hold the new attitude momentarily, and then glance at the airspeed indicator to verify if the new attitude is correct. Due to inertia, the airplane will not accelerate or decelerate immediately…

airplane to lose lateral alignment with the runway centerline and to "skip." [Figure 6-5] The pilot uses rudder pressure to keep the airplane’s longitudinal axis parallel to the runway centerline. This “skipping” is usually indicated by a series ... runway. During these bounces, the crosswind also tends to move the airplane sideways, and these bounces develop into side-skipping. This side-skipping imposes severe side stresses on the landing gear and may result in structural failure. During a crosswind…

more difficult in two ways. The smoothness of the surface has the effect of increasing drag, making acceleration and lift-off more difficult. This can feel as if there is suction between the water and the floats. A little surface ... bubbles between water and the float bottoms. The intermittent contact between floats and water at the moment of lift-off cuts drag and allows the seaplane to accelerate while still obtaining some hydrodynamic lift, but glassy water maintains a continuous…
