First Claim
Patent Images
1. A method for communicating engine status of an aircraft during climb to a pilot, comprising:
- a) accepting from a human a designation of a target range of exhaust gas temperature and a designation of a reference cylinder of the engine;
b) sensing the exhaust gas temperature of the reference cylinder while the aircraft is climbing;
c) communicating to the pilot the sensed exhaust gas temperature and its relation to the target range of exhaust gas temperature.

Abstract
A computer-implemented function monitors and displays exhaust gas temperatures (EGT) in a plurality of cylinders in an engine. The invention provides an easy way to read exhaust gas temperature on a specific cylinder, and to provide a means for leaning the engine while in a climb. Efficient leaning in a climb reduces fuel consumption and reduces the chance of harmful conditions that can lead to engine failure.

2. A method of communicating exhaust gas temperature to a pilot of an aircraft, comprising:
-
a) accepting an indication of a temperature display range, where the temperature display range is within a predetermined range comprising a high temperature alert limit and a low temperature alert limit; b) accepting from a human a designation of a reference cylinder; c) sensing the exhaust gas temperature of the reference cylinder while the aircraft is climbing; and d) displaying to the pilot an indication of the sensed temperature relative to the display range. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)

11. An apparatus for the communication of exhaust gas temperature to a pilot of an aircraft, comprising:
-
a) a plurality of exhaust gas sensors, each mounted with an engine of the aircraft such that the sensor provides a signal representative of exhaust gas temperature corresponding to a cylinder of the engine; b) a display; c) a pilot input system, configured to accept a request for an exhaust gas temperature display and a designation of;
(i) a reference cylinder, and (ii) a target exhaust gas temperature; andd) a controller, configured to use the display to present to the pilot the exhaust gas temperatures provided by the sensors while the aircraft is climbing relative to a predetermined range of temperatures, where the predetermined range comprises a high temperature alert limit and a low temperature alert limit. - View Dependent Claims (12, 13)
