摘要: Systems and methods for enabling charged (ionized) air mass measurement for reliable air data computation onboard an aircraft. Ionic charge sensing may be used to derive air data having improved reliability. The systems and methods for ionic charge sensing employ an emitter electrode and two or more collector electrodes, which electrodes are disposed in proximity to the exterior skin of the aircraft and exposed to ambient air. The emitter electrode is positioned forward of the collector electrodes. The system further includes a solid-state ionic air data module that converts currents from the collector electrodes into air data parameter values. More specifically, the ionic air data module is configured to sense currents induced in the collector electrodes in response to corona discharge produced by the high-voltage emitter electrode.

摘要: A landing marker area light system includes a housing, a first light source, a plurality of second light sources, an optics assembly, a tunable lens, and a controller. The first light source emits a first light beam. The second light sources surround the first light source and each emits a second light beam. The optics assembly receives the first light beam and shapes the first light beam into a first geometric-shaped light beam having a first perimeter. The tunable lens receives the first geometric-shaped light beam and, in response to lens control signals, shapes the first geometric-shaped light beam into a second geometric-shaped light beam having a second perimeter that is different than the first perimeter. The controller supplies the lens control signals to the tunable lens, to thereby control the second perimeter of the second geometric-shaped light beam.

摘要: A system having components coupled to an aircraft in operation processes sensor-derived data, performs a localization cross-checking procedure, and dynamically generates updated analyses of the position and orientation of the aircraft. Based on the updated analyses, the system can generate instructions for flight control of the aircraft and can update flight control instructions as new data is received and processed. The system functions to reduce the “worst-case” bounds on a localization estimate for the aircraft to a low enough level that is appropriate for completing a flight operation.

摘要: A method for controlling a landing gear of an unmanned aerial vehicle (UAV) includes detecting whether a relative-to-ground height of the UAV is greater than a height threshold, where the relative-to-ground height is a vertical height of the UAV with respect to an object; and in response to the relative-to-ground height being not greater than the height threshold and the UAV having not lowered the landing gear, adjusting the relative-to-ground height to the height threshold or above, and lowering the landing gear.

摘要: There are provided systems and methods for providing a barometric altitude monitor that assist pilots by providing alerts when a barometric altitude of the ownship aircraft is may be incorrect. Various embodiments of the present invention determine whether significant errors in barometric altitude occur though comparisons to alternate altitude information sources. Through aspects of the present invention, errors arising from manual entry of barometric pressure information by a pilot may be identified before safety issues arise, thus helping to prevent events such as controlled flight into terrain (CFIT).

摘要: A method for determining position of an aircraft with reference to a location on the ground includes transmitting an acoustic signal from a position on the aircraft to an array of spaced apart acoustic sensors proximate the location. The method includes at least one of (i) determining a time difference of arrival of the acoustic signal between each of the acoustic sensors and a reference acoustic sensor and (ii) determining an arrival time of the acoustic signal at each of the spaced apart acoustic sensors. The position of the aircraft is determined from the time differences of arrival and/or the arrival times.

摘要: A circuit device includes a comparator and a flag signal generation circuit. The comparator includes a first voltage-time conversion circuit to which at least a first input signal is input and which outputs a first time information signal, a second voltage-time conversion circuit to which at least a second input signal is input and which outputs a second time information signal, and a determination circuit that determines magnitude relation of the first input signal and the second input signal, based on the first time information signal and the second time information signal. The flag signal generation circuit generates a flag signal indicating that a voltage difference between the first input signal and the second input signal is a predetermined voltage or less, based on the first time information signal and the second time information signal.
