摘要:
A surveillance system detects potential hazards and alerts the pilot to them. The alerts can be modified to indicate proximity to the predicted path of the aircraft. An autopilot receives instructions from a flight management system (FMS) regarding a planned path and is subject to constraints preempting the planned path. The surveillance system selects which of the planned and a constrained path will be followed for alerting and hazard coding purposes. Means are disclosed to determine when the constrained path will be followed by evaluating the current position of an aircraft, the planned path, and the constraint data.

A method, computer program product and apparatus for locating aircraft with respect to airport runways, generating and annunciating imminent landing situational awareness advisories as a function of aircraft height above runway.
摘要:
Systems and methods for alerting a flight crew when the vertical situation display may be providing incomplete information due to the presence of a non-computed trajectory segment in the flight plan. A processing device in signal communication with a flight management system, a position measuring system, and a velocity measuring system receives a flight plan from the flight management system and determines if the flight plan includes any non-computed trajectory segments. If at least one of time or distance to the beginning of a next non-computed trajectory segment is less than a threshold value, the processing device generates an alert that information displayed on a vertical situation display may be incomplete. An output device outputs the generated alert.

A method, computer program product and apparatus for locating aircraft with respect to airport runways and environs, generating a graphical display of the aircraft position, heading and ground speed information relative to the aircraft runways and environs, and annunciating situational awareness advisories as a function of aircraft information relative to the airport runways and environs.
摘要:
A terrain clearance signal generator particularly usable with ground proximity warning systems provides a signal representative of terrain clearance when the radio altimeter signal is unreliable, such as in the case of excessive pitch or roll, out of track or other conditions resulting in invalid readings. The system monitors such conditions and takes a sample of the last valid radio altitude reading prior to sensing an invalid condition and, upon sensing an invalid condition, updates the sample utilizing barometric altitude signals or integrated barometric altitude rate or inertially-derived Z-velocity signals.
