CWS.
Useful in the L1011.
On all L10 aircraft (except those that were on the British register, or those that were used by GF) CWS can be selected on the ground, and is useful for low level turns immediately after takeoff, where maximum allowed bank angle is desired, due to noise abatement procedures, or obstacles in the takeoff flight path.
Very smooth operation on the 'ole Lockheed tri-motor.
