Abstract: A method for monitoring airplane noise and emissions may include receiving a predetermined set of engine performance data for an airplane and receiving a predetermined set of airplane flight data for the airplane. The method may also include predicting at least one of a noise level and an emissions level from the airplane at each of a plurality of ground based noise and emissions monitoring stations based on the predetermined set of engine performance data and the predetermined set of airplane flight data. Each of the plurality of ground based noise and emissions monitoring stations is located at a predetermined geographic location along an expected flight path of the airplane.

Abstract: The present invention relates generally to barriers for architectural openings, in particular to a screen apparatus and method for screening off an architectural opening. The screen apparatus includes an elongated overhead frame member, a transverse fixed side frame member, a displaceable side frame member, and an elongated articulated bottom frame member. A screen member extends between the frame members, the screen member being interchangeable between a collapsed condition when the screen is open and an extended condition when the screen is closed by movement of the displaceable side frame member.

Abstract: Guiding an aircraft to follow a four-dimensional flight path during a descent with a nominal thrust setting corresponding to idle thrust or non-idle thrust includes monitoring actual along-track position and actual vertical position of the aircraft relative to corresponding desired positions on the flight path, generating control commands based on deviations of the actual vertical position of the aircraft from the desired vertical position, and generating elevator commands based on the deviation of the actual along-track position from the desired along-track position, wherein generating control commands includes, if the deviation of the actual vertical position from the desired vertical position indicates that the aircraft is too low, generating a throttle command to increase the thrust setting to above nominal thrust, and generating a speed brake command to deploy speed brakes when the deviation of the actual vertical position from the desired vertical position indicates that the aircraft is too high.

Abstract: A method for controlling one or more of engine thrust cutback and engine thrust restoration is described which is related to aircraft environmental emissions abatement. The method comprises receiving aircraft location data from at least one navigational sensing system, comparing the aircraft location data against location data identifying an environmental emissions abatement area, and controlling at least one of thrust cutback and thrust restoration of the aircraft engines based on the comparing of aircraft location to the location of the environmental emissions abatement area.
