System and methods provide information to an operator of an engine such that the engine operates with optimal performance, such as maximal fuel efficiency. Such a system may include a plurality of sensors adapted to measure operating parameters of the engine; an engine management system adapted to receive measured operating parameters from the sensors and to generate signals indicative of a current operating performance of the engine and signals indicative of performance-increasing adjustments to current operating parameters; and a display adapted to present symbols in response to signals from the engine management system. The symbols guide the operator to increase or maintain engine performance.
