摘要:
A system and method monitor aircraft state parameters, for example, aircraft movement and flight parameters, applies those inputs to a spatial disorientation model, and makes a prediction of when pilot may become spatially disoriented. Once the system predicts a potentially disoriented pilot, the sensitivity for alerting the pilot to conditions exceeding a threshold can be increased and allow for an earlier alert to mitigate the possibility of an incorrect control input.

A system and method are provided for modifying the position or shape of a premature descent protection envelope with regard to a runway when an aircraft making an approach to the runway is below the nominal approach path and has a flight path angle greater than the nominal approach path angle.

A system and method for selecting a runway, comprises retrieving runway feature data and aircraft data including aircraft heading with respect to the bearing of first and second runways. Runway boundary envelopes are created for each of the first and second runways, each having a predetermined score. A total score for each of the first and second runways is compared to determine which of the runways is selected.

An improved stable approach monitor (SAM) system 100 provides an audible advisory to a pilot when an aircraft is on a final landing approach. More specifically, the SAM system 100 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.

Systems and methods that alert the pilot of the unusual negative pitch attitude. Additionally, the system can bias a "sink rate" envelope toward a more sensitive direction, such that the pilot can be alerted while (or before) a large sink rate is built up during an unusual negative pitch attitude condition.
摘要:
Systems and methods for performing V speeds verification. An example system determines if during a takeoff roll there is enough runway left for the aircraft to stop with a predetermined braking force. If an incorrect "too small" weight had been used to previously compute Vspeeds (e.g., V 1 ) and engine takeoff setting, the predicted point (based on the actual aircraft acceleration) to reach V 1 provides not enough runway length remaining to stop. If such a situation is determined, an alert is outputted to the flight crew.
摘要:
A flap advisory system 100 provides an advisory to a pilot informing that a speed of the aircraft should be attended to because of a current or desired flap setting. More specifically, the flap advisory system compares a measured airspeed of the aircraft either directly to a flap placard speed or to a marginal speed range set below the flap placard speed for a given flap setting. If the measured airspeed is determined to be excessive then the system provides an advisory indicating the airspeed is too fast. Further, the system may provide an advisory when a movement of a flap handle is detected such that continued movement of the flap handle would place the flaps in a setting that is inappropriate for the measured airspeed.
摘要:
Method and corresponding system for improving sink rate alerting for rotary wing aircraft (12). In one example, the system (10) includes a radio altimeter (28) that produces an altitude value, a processor (20) that is in signal communication with the user interface device and the radio altimeter. The processor receives an altitude value, a position value for the aircraft and landing zone information. The processor determines if the aircraft is on an approach to land at a landing zone that is raised above surrounding terrain based on the received position value and landing zone information. The processor receives sink rate information for the aircraft and generates a sink rate alert based on the received sink rate information and the aircraft altitude value if the sink rate information is greater than a sink rate value adjusted according to the landing zone information. An output device (22, 24, 34) outputs the generated sink rate alert. The landing zone information includes an altitude value.
