Abstract:
Methods and apparatus are provided for generating a runway landing alert for an aircraft. The method comprises establishing an altitude parameter and a safety envelope for a designated target runway of the aircraft. A track of the aircraft is monitored with reference to a centerline of the target runway. Any deviation by the aircraft from the centerline of the target runway is detected and determined if it is within a margin of error. If the deviation is within the margin of error, an altitude parameter is increased. If the aircraft is determined to still be maneuvering with respect to the centerline of the target runway, the altitude parameter is decreased. Otherwise, an alert is generated if the aircraft is outside of the safety envelope.
Abstract:
Methods and apparatus are provided for generating a runway landing alert for an aircraft. The method comprises establishing a Runway Awareness Advisory System (RAAS) envelope for the designated target runway of the aircraft. A track of the aircraft is monitored with reference to a centerline of the target runway. Any deviation by the aircraft from the centerline of the target runway is detected and determined if it is within a margin of error. If the deviation is within the margin of error, an altitude parameter of the RAAS envelope is increased. If the aircraft is determined to still be maneuvering with respect to the centerline of the target runway, the altitude parameter of the RAAS envelope is decreased. Otherwise, an alert is generated if the aircraft is outside of the RAAS envelope.

Abstract:
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.
Abstract:
A method for providing alerts or indications to an aircrew of an aircraft that is in-flight and approaching a destination airport includes receiving an aircrew runway selection from the aircrew of the aircraft, automatically generating a probable runway selection by the aircraft, and determining a position of the in-flight aircraft with reference to a threshold point. If the aircraft is prior to the threshold point, the method includes generating alerts and indications to the aircrew based solely on the received runway selection into the FMS from the aircrew of the aircraft and not on the automatically-generated probable runway selection from the aircraft. Alternatively, if the aircraft is past the threshold point, the method includes generating alerts and indications to the aircrew based solely on the automatically-generated probable runway selection from the aircraft and not on the received runway selection into the FMS from the aircrew of the aircraft.
Abstract:
A method and system are provided for generating a low airspeed warning in an aircraft. This method creates a scale factor that is a factor of engine thrust and aircraft altitude. A low airspeed threshold is determined that varies according to the aircraft altitude with respect to a predetermined altitude band and the engine thrust with respect to a predetermined engine thrust band. A low airspeed alert is generated in response to the determination of the low airspeed threshold. This method provides a pilot with earlier knowledge of low airspeed conditions when the aircraft is in a target altitude band, increasing the pilot's response time and thereby enhancing overall aircraft safety.
Abstract:
A system and method are disclosed for indicating to an aircrew of an aircraft a normalized runway icon to ensure visualization of a predicted touchdown point, runway length, stopping distance, energy state marking, and threat conditions, where normalization is referenced to typically available length for landing. Indications of present aircraft locations relative to the icons as well as alerts when thresholds are exceeded are provided.
Abstract:
A system and method are disclosed for indicating to an aircrew of an aircraft an unstable approach to a desired landing. When the energy state of the aircraft exceeds a threshold, a suggested airspeed in consideration of the energy state is displayed. Additionally, a landing spots on a displayed runway are shown indicating where the aircraft would land in view of the energy state and where the aircraft is recommended to land in view of the current aircraft type and weight. A text message may also be displayed that conveys the ability of the aircraft to land.
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.
Abstract:
Embodiments of a flight deck display system deployed onboard an aircraft are provided, as are embodiments of a method carried-out by a flight deck display system. In one embodiment, the flight deck display system includes a cockpit display device and a controller. The controller is configured to: (i) establish the speed trend of the aircraft over a predetermined time period; (ii) generate a primary flight display on the cockpit display device including a speed trend vector graphic representative of the established speed trend; and (iii) alter the appearance of the speed trend vector graphic in a first predetermined manner if a low speed change condition is detected during at least one of aircraft takeoff and landing.
