CONTROL CABLE TRAVEL

737 Classic Flight Deck instrument panel

Making the measurements:
Before removing all the flight control cables I measured the travel of the Elevator, Aileron and Rudder flight control cables, and the angular displacement of the primary flight controls. The travel was measured from mechanical control travel stop to mechanical control travel stop. The cables were rigged as outlined in Boeing's publication "Flight Control Rigging". The tools used to assist in making the measurements are, Starrett DIGITAPE® 16' digital tape measure, for linear measurements and Macklanburg-Duncan SmartLevel® Pro-Series for the angular measurements.
