What is the difference between proportional and non-proportional controls?
Non-proportional controls are the standard for smaller thruster systems. When operated these controls provide full thrust, either to Port or Starboard. When thrusting toward the dock, a quick, offsetting burst away from the dock is typically sufficient to decelerate the bow. Fully proportional controls provide finer operator control. These controls allow zero to full throttling up to the thrusters maximum output for complete control of the bow. These controls make docking virtually effortless since the bow can be manipulated with a touch of the operators finger.
