Abstract: Disclosed is a system and method for diverting from a flight plan without adjusting an autopilot by treating a heading change as the new leg of a flight plan. The present invention allows the pilot of an aircraft to enter a heading to follow into a flight management system, which treats the heading as the current leg of a flight plan otherwise being followed by the flight management system. The present invention graphically displays the heading leg as the predicted track so that the pilot is able to see the airplane's expected path. Such a change allows the autopilot to continue following commands from the flight management system rather than being changed to a mode in which the autopilot follows heading commands directly from the pilot.

Abstract: A computer implemented lean assist function monitors exhaust gas temperature in a plurality of cylinders in an engine along with fuel flow. The lean assist function automatically detects whether the pilot is leaning for best power or best economy and provides an indication to the pilot when the desired fuel mixture has been achieved based on the monitored temperatures.

Abstract: A method, computer program, or apparatus for determining with various degrees of precision the power delivered by an engine, typically, an aircraft engine. The disclosed invention uses a variety of parameters, such as the rotation rate, manifold pressure, outside air temperature, and fuel flow to determine or approximate the power delivered by the engine. The engine's altitude does not have to be involved in the calculations.
