Index

More right-rudder pressure will be needed during the
climbing turn to the right than in the turn to the left
because more torque correction is needed to prevent
yaw from decreasing the rate of turn. In the left
climbing turn, the torque will tend to contribute to the
turn; consequently, less rudder pressure is needed. It
will be noted that the controls are slightly crossed in
the right climbing turn because of the need for left
aileron pressure to prevent overbanking and right
rudder to overcome torque.

The correct power setting for the lazy eight is that
which will maintain the altitude for the maximum and
minimum airspeeds used during the climbs and
descents of the eight. Obviously, if excess power were
used, the airplane would have gained altitude when the
maneuver is completed; if insufficient power were
used, altitude would have been lost.

Common errors in the performance of lazy eights are:
• Failure to adequately clear the area.
• Using the nose, or top of engine cowl, instead of
the true longitudinal axis, resulting in
unsymmetrical loops.
• Watching the airplane instead of the
reference points.
• Inadequate planning, resulting in the peaks of the
loops both above and below the horizon not
coming in the proper place.
• Control roughness, usually caused by attempts
to counteract poor planning.
• Persistent gain or loss of altitude with the
completion of each eight.
• Attempting to perform the maneuver
rhythmically, resulting in poor pattern
symmetry.
• Allowing the airplane to "fall" out of the tops of
the loops rather than flying the airplane through
the maneuver.
• Slipping and/or skidding.
• Failure to scan for other traffic.
