541. - PLT304
To stop pitch oscillation (porpoising) during a winch launch, the pilot should
A) release back pressure and then pull back against the cycle of pitching oscillation to get in phase
with the undulations.
B) signal the ground crew to increase the speed of the tow.
C) relax the back pressure on the control stick and shallow the angle of climb.
