Manual flight implies direct control input- i.e via the yolk in a Boeing, and that would NOT be a normal input while the A/P was still connected
It could be argued the above comment is in contradiction to the flight technique for severe turbulence.
The B737 Supplementary Procedures recommends the autopilot be set to CWS mode. The pilot then is required to manually "fly" the aircraft through the CWS mode. Control forces are slightly higher than in no automatic flight, which in turn decreases the potential for over-controlling in gusts. This is especially important at high altitude where rapid use of aileron causes spoiler actuation and the scene is set for over-controlling by the pilot.
