L-1011 Autoflight: CWS Pitch and Bank Limits (22-17)

When an autopilot is engaged in CWS, the airplane will maintain the existing pitch attitude if it is less than 18 degrees and the existing bank angle if it is less than 35 degrees. If pitch or roll are more than 18 degrees respectively, the autopilot will return the airplane to these limits and then hold it there.

Therefore, pitch and bank limits can be manually exceeded through the control wheel. When control wheel pressure is released, the aircraft will automatically return to the maximum limits.
