摘要:
Systems and methods are provided for controlling a multiple degree-of-freedom system. Plural stimuli are provided to a user, and steady state visual evoked response potential (SSVEP) signals are obtained from the user. The SSVEP signals are processed to generate a system command. Component commands are generated based on the system command, the plurality of components commands causing the multiple degree-of-freedom system to implement the system command.

Systems and methods for identifying ownship deviation from assigned taxi-clearance in the area of taxiway intersection. An exemplary system provides alerts in the event of a significant deviation from the assigned clearance, but does not give unwanted alerts when the flight crew is performing normal turning maneuvers in the area of an intersection.

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.

Systems and methods for advising a flight crew member that an enhanced ground proximity warning system (EGPWS), for example, may continue to provide terrain alerts, cautions, warnings, or the like because an intended landing site for the aircraft is not recognized within a database of airports. An unknown airport advisory is generated and broadcast after the aircraft is in a landing configuration, when the aircraft is greater than a threshold distance from the nearest landing site in the database, but before the terrain alerts are broadcast. The pilot may actuate a “terrain inhibit” selection device after receiving the advisory. The inhibit device may deactivate or mute subsequent alerts generated by the EGPWS during that particular landing sequence.

Methods and systems for determining reliability of Global Positioning System (GPS) ground speed. An example system receives GPS track information and GPS ground speed, determines a change in GPS track information and determines reliability of the GPS ground speed based on the determined change in GPS track information relative to the GPS ground speed. The system sets a GPS ground speed based on the determined reliability. A GPS ground speed output is set to zero, if the GPS ground speed is determined unreliable and the GPS ground speed output is set to the GPS ground speed, if the GPS ground speed is determined reliable. The system sends the GPS ground speed output to a Runway Awareness and Advisory System (RAAS). Also, the system sets the GPS ground speed output to zero, if a received GPS ground speed validity signal or a received GPS track validity signal indicate invalid.
摘要:
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.

摘要:
An improved stable approach monitor (SAM) system provides an audible advisory to a pilot when an aircraft is on a final landing approach. More specifically, the SAM system compares a measured airspeed of the aircraft to a predetermined flap placard speed. If the measured airspeed exceeds the predetermined flap placard speed then the improved SAM system provides an audible advisory indicating the airspeed of the aircraft is too fast. Advantageously, this audible advisory should prevent the pilot from attempting to deploy the flaps at an excessive airspeed and in turn focuses the pilot's attention on the problem at hand, which would be to reduce the airspeed of the aircraft. Once the airspeed is equal to or below the predetermined flap placard speed, the improved SAM system may provide another audible advisory informing the pilot to commence deployment of the flaps.
摘要:
A system implementable in an aircraft for generating a warning includes a processor, a first component configured to receive from a user a desired aircraft control-surface takeoff configuration, a second component configured to provide to the processor a first signal indicative of a current control-surface configuration of the aircraft, and a third component configured to provide to the processor a second signal indicative of the position of the aircraft. The processor may be configured to compare the aircraft position to the contents of a database, determine, based on the comparison, whether the aircraft is on a departure runway from which the aircraft is to depart, and generate an alarm if the aircraft is on the departure runway and the current control-surface configuration is different from the desired control-surface takeoff configuration.
摘要:
A terrain awareness system and method which provides increased warning times to the pilot of an aircraft of a hazardous flight condition while minimizing nuisance warnings. An important aspect of the invention is that the terrain background information as well as the terrain advisory and warning indications may be displayed on a navigational or weather display, normally existing within an aircraft, which reduces the cost of the system and obviates the need for extensive modifications to existing displays, such as a navigational and weather radar type display.
