A prototype hybrid terrain database is being developed in conjunction with other databases and with hardware and software that constitute subsystems of aerospace cockpit display systems (known in the art as synthetic vision systems) that generate images to increase pilots’ situation awareness and eliminate poor visibility...

Power User Interface 5.0 (PUI) is a system of middleware that is an alternative to the computer program described in the immediately preceding article. Written for PUI enables expedited ordering of data granules on the basis of specific granule-identifying information that the users already know or can assemble. PUI also...

Monolithic focal-plane arrays of photodetectors capable of imaging the same scenes simultaneously in multiple wavelength bands in the visible and infrared spectral regions have been proposed. In prior visible/infrared imaging systems, it has been standard practice to use separate optical...

An algorithm processes cloud-physics data gathered in situ by an aircraft, along with reflectivity data gathered by ground-based radar, to determine whether the aircraft is inside or outside a cloud at a given time. A cloud edge is deemed to be detected when the in/out state changes, subject to a...
