Abstract: A system and method of shifting a premature descent protection envelope for an aircraft has been developed. First, a premature descent protection envelope (PDP) is determined including a first boundary at a first distance from the runway. Next, a nominal approach path is determined for approaching the runway and an approach path angle. Also, a flight path angle of the aircraft is determined. The first boundary is shifted in an upward direction from the runway in response to the aircraft being below the nominal approach path, and the flight path angle being greater than the nominal approach path angle.

Abstract: Methods and systems are provided for automatically predicting a surface movement path of an aircraft. The method comprises collecting historical aircraft trajectory data from an empirical aircraft path database. Next, aircraft trajectory paths for a designated airport are mapped based on the historical aircraft trajectory data and map data for the designated airport. Different aircraft trajectory paths are each assigned a weight for the designated airport. A graphical display is then generated for each of the aircraft trajectory paths for the designated airport along with a table that identifies a most probable terminal area and entry node for use by the aircraft at the designated airport.

Abstract: 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.

Abstract: A system and method for passively detecting aircraft wingtip strikes includes generating a digital base map represented by a plurality of aerodrome cells. A numeric value representative of the specific wingtip is assigned to each of the aerodrome cells. An index count array is generated that has a separate entry for each numeric value. A digital aircraft structure representative of an aircraft is generated, and is represented by a plurality of aircraft cells. A determination is made as to whether a portion of the aerodrome cells are or would be replaced with the plurality of aircraft cells. Each numeric value of the aerodrome cells that are or would be replaced is counted to determine a replacement count associated therewith and that is entered into the separate entry in the index count array for that numeric value. One or more potential aircraft wingtip strikes are detected based on the replacement counts.

Abstract: A system and method provide an alert to a pilot of an aircraft aurally with a given volume and inflection, and/or visually with a text message which includes color, font, and pitch (size). The alert is rendered in distinct fashion for the expected and unexpected cases, e.g., an intended runway and an unintended runway. In a preferred embodiment, the alert for the intended runway is changed to a confirmation level, or one that is less likely to interfere with other information flow, while the alert for the unintended runway would be provided in a more conspicuous manner.
