Abstract: A system and method for providing automatic from-waypoint updating includes determining when a flight plan has been received that includes rendering a lateral map image that includes an aircraft icon and a flight leg to be captured. A variable position user input device supplies a signal representative of its position. A processor processes the signal from the variable position user input device and commands a display device to render a trajectory line graphic that (a) extends from the aircraft icon in a direction that corresponds to the position of the variable user input device and (b) intersects the at least one flight leg to be captured. The flight plan is automatically updated to designate the waypoint at the start of the at least one flight leg as a from-waypoint.

Abstract: A system method for providing aircraft lateral navigation system capability feedback to a pilot includes determining, in a processor, when a flight plan has been received that includes a flight leg that needs to be captured by the aircraft. A determination is made, in the processor, when an armed signal has been received, where the armed signal indicating that an aircraft autopilot navigation mode (NAV) has been armed. The processor is used to command a display device to render the flight leg using a first display paradigm when the armed signal has not been received, and to render the flight leg using a second display paradigm when the armed signal has been received.

Abstract: A method and system for maintaining visual vertical reference on a rotorcraft display during rotorcraft landing is provided. The method generates vertical poles and positions them on the rotorcraft display such that vertical reference as well as roll information may be quickly and easily comprehended by a pilot.

Abstract: Methods and apparatus are provided for an azimuthal equidistant projection (AEP) aircraft navigational display. The apparatus comprises a generator providing the aircraft's current latitude and longitude (?1,?0), a user input for providing the desired map radius R, a display for presenting the navigational information, a map data source providing topographical information associated with geo-spatial coordinates, and a controller and memory coupled to the generator, data source, input and display for providing data transformations. Map data containing topographical information associated with each geo-spatial coordinate is obtained from the map data source for an area of approximately radius R from (?1,?0). Using the controller and memory, the geo-spatial coordinates are converted to AEP spatial coordinates so that the topographical information is now associated with such AEP spatial coordinates.

Abstract: The combustion control system described herein is the top assembly of a combustion chamber. It was developed as part of an efficient wood burning fire place. The assembly presumes that there is some sort of baffle above the fire directing the flames to the front and a non-airtight glass door. The object is to burn cleanly, efficiently, with a minimum of creosote on the glass and with a relatively low cost non-airtight construction. A single damper blade regulates the flue opening, the combustion air supply and dilution air for the chimney. The blade also acts as a deflector to provide a long combustion path and heat extraction. A bimetal element automatically adjusts the damper as the combustion process changes.

Abstract: A gas and solid fuel burning chamber is provided with a control system for the safe and efficient operation of a gas burner. The simple control system uses multiple thermocouples in series to permit the safe operation of the gas burner in a vented device without the need for a draft hood. A combination of gas and solid fuel is demonstrated where gas can be used to start the solid or as an independent source of heat. The control system comprises generally of thermocouples for measuring the flame temperature, the combusted gas temperature and the overall chamber internal temperature and producing signals to regulate the flow of fuel to the gas burner in response thereto.
