    摘要: Systems and methods for intelligently alerting the flight crew of a cabin depressurization. An example system includes a cabin altimeter that generates a cabin pressure value, an alerting device, such as a speaker system and a processing device in data communication with the cabin altimeter and the alerting device. The processing device determines if there is a problem with the cabin pressure received from the cabin altimeter, determines rate of change of the cabin pressure, and sets at least one of an alert volume or an alert frequency based on the cabin pressure and the rate of change of the cabin pressure if it was determined that a problem exists with the cabin pressure. The processing device also issues a cabin depressurization alert over the alerting device based on at least one of the set alert volume or alert frequency, if there is a problem with the cabin pressure value.

    摘要: Systems and methods for outputting instructions when a vehicle is not responding to a roll-angle alert. An example system includes one or more altitude sensors that determine one of altitude above ground level or barometric altitude, one or more roll-angle sensors that determine the roll-angle of the vehicle, and a processor. The processor receives the altitude and roll-angle information, determines if an excessive roll-angle condition exists based on the received altitude and roll-angle information, and generates a roll-angle alert signal if a roll-angle alert condition exists. The processor generates a roll-direction signal based upon vehicle position relative to the horizon and outputs the determined roll-direction signal via the one or more output devices, if one of the condition still exists after the time delay, the vehicle roll-angle has deteriorated away from the desired threshold, or the roll-angle rate is greater than a roll-angle rate threshold.

    摘要: Methods and systems for providing a depressurization alert. An example method includes receiving a cabin depressurization discrete signal, determining if the cabin depressurization discrete signal is valid, and issuing a cabin depressurization alert, if the cabin depressurization discrete signal was determined to be valid. In accordance with further aspects of the invention, a time delay is executed before the receiving, determining, and issuing steps are repeated. The cabin depressurization discrete signal is determined not valid if uncorrected pressure is not greater than a predefined altitude. The uncorrected pressure is a raw pressure value produced by a Pitot-Static system. Also, the cabin depressurization discrete signal is determined not valid if the aircraft's altitude above an intended runway is not greater than a first predefined value. Additionally, the cabin depressurization discrete signal is determined not valid if an aircraft's altitude above terrain is not greater than a second predefined value.

    摘要: A system and method for selectively alerting a pilot of an aircraft about distance remaining to the end of a runway. A position of the aircraft is received. A position of a runway is retrieved from a runway database. The retrieved position of the runway is compared to the received position of the aircraft to determine if the aircraft is within an alert envelope relative to the retrieved position of the runway. The position of the runway is subtracted from the position of the aircraft to determine a distance to the distal end of the runway. An alert to the pilot is generated based upon the distance to the distal end of the runway.

    摘要: A method, system, and computer program product for rendering an image to available display area based on parameters of one or more unusable display areas. The method includes determining one or more trapezoids for defining the available display area based on the parameters of the one or more unusable display areas. After an image is generated, the method determines if the generated image is within the determined one or more trapezoids, and renders the components of the generated image that are determined to be located within the one or more trapezoids.

    摘要: Systems and methods for generating an alert if a rotary wing aircraft is approaching a hazardous situation. In an example method a processor receives a wind value and a rate of descent value. An alert signal is generated if the received wind value is greater than a tailwind threshold value and the rate of descent value is greater than a rate of descent threshold value. The generated alert is outputted to an output device, such as a display device or speakers. The alert signal is further generated if the rotary wing aircraft is on approach to landing, a rate of change of heading is less than a predefined value, or a rate of change in speed is less than a predefined value.

    摘要: Systems and methods for determining if an aircraft is approaching a atmospheric pressure at field elevation (QFE) airport and for alerting if any errors that might affect the production of an accurate altitude value. In an example method a global positioning system (GPS) altitude value is compared to a corrected barometric altitude, if an airport that the aircraft is proximate to (approaching) is a QFE airport. The field elevation of the proximate airport is added to the corrected barometric altitude to generate an adjusted barometric altitude, if the comparison between the GPS altitude and the corrected barometric altitude is greater than a predefined threshold. The adjusted barometric altitude is sent to relevant aircraft systems, such as an Enhanced Ground Proximity Warning System.
